    LIFTING EQUIPMENT MONITORING SYSTEM AND METHOD OF CONTROLLING THE MEDIUM
    OF SUCH A SYSTEM
    GENERAL TECHNICAL FIELD AND PRIOR ART
    The present invention relates to the field of control of a hoist.
    On a construction site, including construction, many construction equipment is used including lifting equipment to move or lift loads of large masses, for example greater than several tons. Such lifting devices may be, for example, cranes, excavators, etc.
    A hoist must be regularly checked, in particular to ensure safety when lifting large masses. In practice, a control of a hoist is difficult to implement since a large mass load is not always available at the place of control (construction site, storage location of the hoist, etc ...). In addition, each lifting device can lift a different maximum load, which requires to have a plurality of different mass loads or a load whose mass is adjustable.
    In a known solution, the person carrying out the control carries, to the place of control, different elementary charges in order to form a charge having the desired mass. Such a solution has a high cost as well as a complex logistics.
    To solve these drawbacks, the patent application WO 99/27330 A1 discloses an impermeable bag which can be filled with water in order to control the lifting of a machine. Such a bag is stored and transported empty, which is advantageous. However, it is necessary to have a large amount of water at the place of control to fill the bag, which has a disadvantage. In addition, after the control, the bag is emptied and the water is thrown away, which is problematic in the current context in which taking into account the environment is more and more important. The invention therefore aims to remedy these disadvantages by proposing a new control system.
    GENERAL PRESENTATION OF THE INVENTION To this end, the invention relates to a system for controlling the capacity of a hoist to lift a test load, the system comprising at least one rigid bucket capable of being filled with aggregates so as to forming said test load, the bucket comprising suspension means adapted to be connected to the hoist to control its lifting capacity.
    Thanks to the control system according to the invention, it is easy to form the test load on a construction site or a storage location by filling the bucket with aggregates, which are easy to find. By aggregates, we mean gravel, soil, sand, etc.
    Preferably, the control system comprising at least a first rigid bucket and a second rigid bucket, the first bucket comprises fastening means to said second bucket. Thus, it is possible to increase the mass of the control system by fixing several skips together.
    According to a preferred aspect, the system comprising at least a first rigid bucket and a second rigid bucket capable of being filled with aggregates so as to form said test load, the first bucket comprises fixing means to said second bucket and means of suspension adapted to be connected to the hoist to control its lifting capacity. Thus, the adjustment of the mass of the test load is easy.
    Preferably, the fixing means comprise a clamping system which is easy to put in place. Preferably, the fixing means are configured to connect a lower portion of the first bucket to an upper portion of the second bucket to suspend the second bucket to the first.
    According to a preferred aspect, the first bucket is adapted to fit into the second bucket during its transport in order to reduce the size and thus make it easy transport and storage of the control system.
    Advantageously, the second bucket comprises securing means to a transport trailer to secure the position of the control system on the trailer during transport. Preferably, the securing means comprise a plurality of securing members, preferably distributed at the periphery of the second bucket. Preferably, each lashing member is adapted to cooperate with a securing member of the trailer. Thus, the control system is properly maintained in the trailer during transport.
    Preferably, the first bucket is adapted to be fixed above the second bucket so that the control system is stable during its lifting.
    Preferably, the first bucket and the second bucket extending longitudinally, the first bucket and the second bucket are adapted to be fixed orthogonally to further stabilize the control system during its lifting.
    Preferably, each bucket has a length less than 3m, a width less than 2m and a height less than 2m to allow easy transport and storage of the control system. The invention also relates to a set of a hoist to control and a control system connected to said hoist. The invention further relates to a method of controlling the capacity of a hoist to lift a test load by means of a control system comprising at least one bucket, the method comprising: a filling step of at least one bucket; minus a bucket with aggregates to form a test load, a step of connecting said bucket to the hoist, and a step of lifting said bucket to a predetermined height by the hoist so as to control the proper operation of said hoist.
    Preferably, the method comprises a step of weighing the dump body, in particular, by means of a load cell.
    Thanks to the control method according to the invention, the test load is easy to form on a control place because the bucket can be filled with any type of aggregates.
    Preferably, the control system comprising at least a first bucket and a second bucket, the method comprises: a step of filling the first bucket and the second bucket with aggregates, a step of fixing the first bucket above the second bucket to form a test load, a step of connecting said first bucket to the hoist, and a step of lifting said first bucket to a predetermined height by the hoist so as to control the proper operation of said hoist.
    Thus, the mass of the test load is easily adjustable by fixing several bins.
    Preferably, the first bucket and the second bucket extending longitudinally, the method comprises a step of fixing the first bucket orthogonal to the second bucket so that the control system is stable during the lifting step.
    Preferably, the filling step is performed by the hoist to be controlled, preferably by an excavator. Thus, no other gear that the gear to control is necessary during the control.

    DESCRIPTION OF ONE OR MORE MODES OF REALIZATION AND IMPLEMENTATION
    A hoist is used on construction sites to lift large loads, for example greater than several tons. To do this, a load is connected to the hoist at an anchor point of said hoist. To ensure safety on the job site, the lifting gear is regularly checked, in particular by a lifting test to control the mass that can lift the lifting gear at its anchor point.
    According to one embodiment of the invention, with reference to FIG. 1, there is shown a system 10 for controlling the capacity of a hoist (not shown) to lift a test load. Such a test is performed at a control site that may be a construction site or a storage location of lifting gear. The control system 10 comprises a first bucket 1 and a second bucket 2 fixed under the first bucket 1. Each bucket 1.2 comprises suspension means to the hoist and tilting means, the suspension means and the tilting means being adapted to be connected to a hoist at its anchor point.
    The first bucket 1 is in the form of a tank, having an upper opening, and is adapted to be filled with aggregates G, such as sand, gravel, soil, etc., introduced through the upper opening so to increase the mass of the first bucket 1. The first bucket 1 is rigid and made of aluminum, steel or any other rigid material capable of allowing the first bucket 1 to maintain its shape when placed on the ground in order to The first bucket 1 comprises a bottom wall, or bottom wall, and a lateral belt extending at the periphery of the bottom wall and comprising two side walls, a rear wall and a front wall.
    Preferably, the bottom wall extends substantially horizontally, the side walls and the rear wall extend vertically and the front wall is inclined relative to the vertical. The terms horizontal and vertical are linked to the ground when the first bucket 1 is placed on said ground. The lateral belt comprises an upper edge 13 at the upper ends of the walls of the lateral belt. The upper edge 13 has a thickness greater than the thickness of the walls of the lateral belt. Such an upper edge 13 thus forms an attachment zone of the first bucket 1, for example by clamping with the aid of a jaw system 15 as will be presented later.
    The first bucket 1 extends longitudinally along a first longitudinal axis Xi and has a length less than 3m, a width less than 2m and a height less than 2m. Such a first bucket 1 thus has contained dimensions to make it easy to transport and store. Such a first bucket 1 can thus be transported on a trailer R hitched to a passenger vehicle V.
    The first bucket 1 comprises suspension means to the hoist to allow lifting of the first bucket 1. In this example with reference to Figure 1, the suspension means are in the form of four suspension rings 11 extending vertically and projecting from the first bucket 1 at the upper edge 13 and being adapted to be connected to the hoist by slings E. E slings are connected to the hoist at the level of anchor point of the hoist. When the hoist lifts the first bucket 1 via its suspension means, the first bucket 1 remains substantially horizontal so that the aggregates G remain in the bucket 1. To measure the mass of the control system 10, a peson P is, preferably, placed between the first bucket 1 and the hoist, preferably between the slings E and the hoist. Suspension means have been presented in the form of four suspension rings 11, but it goes without saying that the number of suspension rings 11 could vary. Similarly, all other forms of suspension means, for example hooks, could be suitable.
    Referring to Figure 2, the first bucket 1 comprises tilting means in the form of two tilt rings 12 extending externally and projecting from the rear wall of the first bucket 1 to empty the first bucket 1 Aggregates G. The tilt rings 12 are adapted to be connected to the hoist by slings E to tilt the first bucket 1 during lifting thereof by the tilting means. When the hoist lifts the first bucket 1 by the tilting means, the first bucket 1 leans forward which allows to empty the aggregates G of the bucket 1. When tilting the first bucket 1, the Inclination of the front wall facilitates the emptying of aggregates G. It has been presented tilting means in the form of two tilt rings 12, but it goes without saying that the number of tilt rings 12 could vary. Likewise, any other form of tilting means could be suitable.
    In particular, as the tilting means are provided on the rear wall and the front wall is inclined, the first bucket 1 can be emptied quickly and optimally forward when tilting the first bucket 1.
    The second bucket 2 has a shape and a function similar to the first bucket 1, also the longitudinal axis Xi, the suspension rings 11, the tilt rings 12 and the upper edge 13 are respectively designated X2, 21, 22 and 23 for the second skip 2. For the sake of clarity, only the significant differences between the two skips 1.2 will now be presented.
    Thus, similarly to the first bucket 1, the second bucket 2 has tilting means on the rear wall and a front wall inclined to facilitate the emptying of the second bucket 2.
    In this example, the first bucket 1 has dimensions, in particular in length and width, smaller than those of the second bucket 2 to allow the interlocking of the first bucket 1 in the second bucket 2. This reduces the congestion of the control system 10, which further simplifies its transport and storage.
    The first bucket 1 and the second bucket 2 can be connected together in order to increase the mass of the control system 10. To do this, the first bucket 1 comprises means for attachment to said second bucket 2. The fixing means illustrated in FIG. FIG. 1 is in the form of fastening brackets 14 projecting from the side walls of the first skip 1 and towards the outside of said first skip 1. Preferably, the first skip 1 comprises four fastening fittings 14 a left front bracket and a left rear bracket, projecting from the left side wall, and a right front bracket and a right rear bracket, projecting from the right side wall. Each fixing fitting 14 comprises an orifice in which is mounted a jaw system 15 adapted to clamp a fastening fitting 14 with the upper edge 23 of the second skip 2.
    When the buckets 1, 2 are fixed together, the first bucket 1 is above the second bucket 2. Thus, the second bucket 2 having dimensions and a larger mass, the center of gravity of the control system 10 is low which ensures stability when lifted by a hoist. In addition, the first bucket 1 and the second bucket 2 are fixed orthogonally. In other words, the first axis Xi of the first bucket 1 and the second axis X2 of the second bucket 2 are substantially orthogonal. Thus, the projected area of the system 10 being higher, the distribution of the mass of the control system 10 is improved, which improves its stability.
    As illustrated in FIG. 3, the control system 10, comprising nestable buckets 1, 2, can easily be transported by means of a standard trailer R towed by a passenger vehicle V, allowing easy movement up to 'instead of control. Advantageously, the control system 10 has a mass of less than 750 kg, preferably less than 600 kg, so that the trailer R has a mass of less than 1000 kg, preferably less than 880 kg, when the system 10 is mounted on the trailer A. This allows an operator, holder of a conventional driving license, to transport the control system 10 on a trailer R. The operator does not need a specific driver's license, which is advantageous .
    According to one aspect of the invention and still with reference to Figure 3, the second bucket 2 comprises securing means to a transport trailer R to fix the control system 10 to the trailer R for transport. In this example, the securing means comprise a plurality of securing members 24, the trailer R comprising a plurality of securing members S adapted to cooperate with the securing members 24.
    The securing members 24 are in the form of hooks (not shown) distributed at the periphery of the second bucket 2 and extending projecting and externally to the walls of the side belt. Preferably, the second bucket 2 comprises four hooks: a left front hook and a left rear hook protruding from the left side wall and a right front hook and a right rear hook projecting from the right side wall . The securing members S are in the form of rings attached to the trailer R and adapted to cooperate with the hooks of the securing members 24. In practice, the trailer R comprises four rings configured to maintain, by lashing, the bucket 2 to the R. trailer
    In the following description, it will be presented an implementation of the control method of a hoist using the control system 10 described above.
    In order to control a hoist, an operator first transports the control system 10 on a trailer R to the place of control. During transport, the buckets 1, 2 are nested. Once at the place of control, the control system 10 is detached from the trailer R. To do this, the securing rings S of the trailer are loosened and then removed from the tie-down hooks 24 in order to release the second bucket 2.
    E slings are then connected, on the one hand, to the hoist at the anchor point and, secondly, to the suspension rings 11 of the first bucket 1 to move said bucket 1 on the ground where it is detached from the hoist. Similarly, the second bucket 2 is connected to the hoist, moved on the ground and detached from the hoist. A handling machine, for example an excavator, then fills the buckets 1, 2 of G aggregates available at the place of control, for example, by digging the ground. The first bucket 1 is then connected to the hoist, a peson P being placed between the slings E and the anchor point. Then, the first bucket 1 is lifted by the hoist so as to be placed above the second bucket 2 and orthogonally thereto. Then the jaws 15 are, on the one hand, mounted in the fastening brackets 14 of the first bucket 1 and, on the other hand, hooked to the upper edge 23 of the side walls of the second bucket 2 in order to secure the buckets 1, 2.
    Once the buckets 1, 2 filled and fixed together, the control system 10 is able to control the hoist. The control system 10 is then raised by the hoist to a predetermined test height. The mass of the control system 10 is then checked using the P-scale to form a predetermined mass test load. The mass of the test load is, in known manner, determined for each hoist according to its specifications. The mass of the system 10 can be modified by modifying the filling of the buckets 1, 2 or by using granules G different, more or less dense.
    Once the mass of the control system 10 is the predetermined mass for a lifting test of the hoist, the control system 10 is held at a predetermined test height for a predetermined test time. The test height is determined so as to ensure that the entire mass of the control system 10 is lifted by the hoist during the control. The test time is, in known manner, determined according to test standards. At the end of the test time, the control system 10 is placed on the ground, the first bucket 1 is detached from the hoist and the second bucket 2 is detached from the first bucket 1.
    To empty the first bucket 1, the slings E are connected to the tilt rings 12 of the first bucket 1 to be emptied via the slings E. Then, the first bucket 1 is again raised by I hoist. The position of the tilt rings 12 does not allow lifting of the bucket 1 in a stable horizontal position, the bucket 1 tilts forward which has the effect of emptying the aggregates G present inside the bucket 1. The second bucket 2 is emptied in a similar manner.
    When the first bucket 1 and the second bucket 2 are empty, the first bucket 1 is nested in the second bucket 1 thanks to the lower dimensions of the first bucket i with respect to the dimensions of the second bucket 2.
    The second bucket 2 is then connected to the hoist and then moved to the trailer R to be stowed. The step of filling the bucket 1, 2 with a handling machine is particularly advantageous in the case of control of an excavator. Indeed, in this case, the excavator is both the lifting gear to be controlled and the handling machine capable of filling the buckets 1, 2. Thus only the excavator to be controlled is necessary to perform a control.
    It has been presented the lifting of the two skips 1.2 of the control system 10, however it goes without saying that the hoist could lift only one skip if the necessary test mass is low. In particular, if the test mass of the hoist is less than 2.8 tonnes, only the first bucket 1 is lifted by the hoist, if the test mass is less than 3.7 tonnes, only the second bucket 2 is lifted.
    It has been presented a control system 10 comprising two skips 1.2, however it goes without saying that it could include more than two skips nested in each other during the transport of the system 10, and connected one above others when checking a hoist.
    Thanks to the control system according to the invention, a bucket can be filled with any type of aggregates, which makes it easy to form a test load on a control site (construction site, place of storage of fishing gear). lifting, etc ...) on which it is common to have aggregates, in particular by digging the soil near said place of control.
    Advantageously, the relative position of the buckets between them during lifting, in particular their mounting one above the other and orthogonally, allows a stability of the control system during its lifting, which improves the safety during the control.
    Advantageously, once the control is carried out, the aggregates are emptied from the bucket and can be used normally as they would have been without control. Thus there is no aggregate loss due to the control of a hoist which allows respect for the environment. When the aggregates are taken from the soil, they can be put back at the end of the test.
    Advantageously, the control system is easily transportable because of its mass. In addition, the nesting of skips reduces the volume of the control system during its transport and storage which reduces logistics costs.
    Thanks to the invention, a lifting control can be realized in a practical and fast manner.
