Description
- The invention is comprised in the technical field of lifting loads with cranes, including on site tower cranes, derrick cranes or any other type of crane.
- Currently, jobs for leveling a load suspended by a crane are performed manually by shortening or lengthening the chains or slings holding the part to the crane hook. The suspended loads are rested as many times as there are chain or sling shortening or lengthening operations necessary for the purpose of carrying the load with the inclination necessary to its final destination.
- There is no machine on the market which performs these operations mechanically and remotely in a completely autonomous manner and capable of working in special conditions.
- The object of the invention is a machine which, connected to the crane hook, is capable of shortening or lengthening the chains or slings mechanically and remotely, preventing the continuous handling of the suspended load by operators, thus making the load leveling operation a safe and fast operation.
- The object of the invention is to also provide a radio control-operated autonomous load leveler for cranes capable of working in explosive environments, environments with radio interferences, underwater environments, sterilized environments, for the food, hospital, laboratory fields, etc.
- The remote control autonomous load leveler is a machine designed for being suspended from a crane hook. Provided with an electric generator and a radio control system which assure complete autonomy and allow operating the blocks and tackles remotely, it thereby achieves that the load suspended from the four hooks is handled at the desired position and at a distance that is safe for operators, all with the suspended load.
- The invention can be used in assembling rebars and inclined column formwork for bridges, viaducts, etc. It can also be used in assembling inclined structures, allowing doing the work of two or three cranes with just one. The load leveler especially further allows the assembly of any part needing beckets having different lengths, since the load leveler allows performing this operation with the suspended load.
- The use of a remote control load leveler in traffic accidents would substantially simplify the tasks of hitching, hoisting and subsequently placing the damaged vehicles in the transport position, equally reducing the time that the road is closed.
- The present invention can also supply electric power, hydraulic power or both to several crane accessories which up until now were manually operated. For example, it allows supplying electricity to a pump for bailing out water which, suspended from the leveler, prevents having to use electrical extension cords in flooded areas and even an operator having to go to each pumping point to place the pump.
- When building retaining walls, the footings or the walls are often prepared for pouring concrete, and due to rain or the appearance of cracks the batter becomes unstable and dangerous for workers. The leveler can supply electricity to a concrete bucket opened electrically and to an electrovibrator. It can likewise have both suspended, concrete and vibrate the concrete without operators on the formwork, which is not safe due to the proximity of the batter.
- The autonomous load leveler provides another series of advantages:
- It is capable of suspending a part or structure from the transport position to its final destination, being adjusted to the angle of inclination required and thereby preventing the operators from continuous handling the load, lengthening or shortening the anchoring chains as needed.
- Due to its versatility, the load leveler entails optimizing tasks which would have been carried out by more than one crane; the precision necessary for assembling certain structures often makes it necessary to use three or even four cranes. A single crane would be enough with the use of the load leveler.
- It provides considerable savings by reducing both the number of necessary crane and essential personnel hours for the leveling tasks.
- It allows automating instruments which, to date, have been manually operated (concrete bucket, concrete vibrator, water pump, etc.), supplying them the electric and/or hydraulic power necessary to operate, these being handled at a safe distance.
- In terms of on-the-job safety and hygiene, the load leveler also provides a series of advantages:
- At construction sites, one of the jobs to be performed by a tower crane is transferring and turning over the debris containers and boxes. This operation is performed by the crane operator moving to the unloading point, supporting resting the container, to release the two front chains and lift the box again so that it is tipped and unloaded. It is very common in such sites for the unloading point to be very hard for the crane operator to access and even dangerous when providing internal reinforcement for the walls of the site since the chains have to be released at the unloading point with the box supported on the wall. By using the load leveler, not only is the movement of the crane operator through non-conditioned areas prevented, but also the crane operator or any other operator handling the box for unloading it is prevented.
- When operating a forklift with a safety cage, the cage can be lifted with the leveler, which therefore allows releasing the load without any operator having to go to the unloading point for the purpose of lifting the cage and thus recover the lift.
- In construction sites for building retaining walls, it is very common due to rain for cracks to appear; for the, ground to show little resistance, etc., thereby compromising the stability of the batter. When the formwork is ready for concreting and the batter becomes unstable and dangerous for the operators who are responsible for pouring the concrete (on the formwork) and vibrating it, the load leveler can be used as follows: the electric-driven concrete bucket is suspended from the leveler support, and an electric concrete vibrator is suspended from the block and tackle. The load leveler supplies electricity and drive at a safe distance for both tools, which thereby allows precisely pouring the concrete and then lowering the vibrator to allow it to perform its function. Areas in which safety prevents site personnel from working as it would involve assuming personal risks can thus be concreted.
- When assembling structures, slings are commonly used. Their elasticity causes differences of several centimeters in length from one to the next. This is because some are subjected to a greater load than others, the more weight they support the more they are stretched. In other cases, the sections surrounding slings have different thicknesses, the anchoring points are not symmetrical, the structure is placed with a slight inclination, etc. For this reason, the attempt is usually made to correct these small differences with very rudimentary and dangerous methods, either by operators swinging, prying or handling the load with operators when it is still suspended. The load leveler absorbs any length difference of the slings, giving the structure assembly operation the precision necessary to prevent the suspended part from being handled by the operators in a dangerous situation.
- A series of drawings aiding to better understand the invention and expressly related to an embodiment of said invention presented as a non-limiting example thereof is very briefly described below.
-
Figure 1 shows an embodiment of the autonomous load leveler. - In a first preferred embodiment, the present invention comprises four fundamental parts:
- An electric generator with a radio control start responsible for supplying the electricity necessary for operating the remaining electric parts.
- At least one electric or hydraulic block and tackle and a maximum of as many blocks and tackles as there are leveling points required, a maximum of four blocks and tackles being the most common. This block and tackle or group of blocks and tackles is responsible for placing the suspended part in the desired position.
- An industrial radio control receiver/emitter with dual buttons, one for starting/stopping the electric generator, one for starting/stopping the electrohydraulic pump if there is one, and at least one for each block and tackle installed, the function of which is to operate the electric blocks and tackles or the electrovalves if hydraulic blocks and tackles are installed.
- A structure or support the purpose of which is to house the blocks and tackles, the electric generator, the industrial radio control receiver and the electrohydraulic pump with its electrovalves, there being as many of the latter as there are hydraulic blocks and tackles if there are any installed, allowing the assembly to be suspended from a crane and in turn suspending from such crane the load that must be leveled.
- The generator can thereby be started and the blocks and tackles can be individually operated, all radio control-operated, thereby handling a suspended load, leveling it at the desired position remotely. The load can thereby be handled and included for adapting it to any position by lengthening and shortening the chains of the blocks and tackles from a safe distance with respect to the suspended load.
- In another preferred embodiment, the radio control-operated autonomous load leveler for cranes allows configuring a previous autonomous load leveler so that it can work in different particular working environments. A radio control-operated autonomous load leveler for cranes can be configured so that it can perform its function both underwater, in inside sites without ventilation, in the mining industry, food industry, pharmaceutical industry, etc. It comprises a radio control-operated autonomous load leveler for cranes similar to that of the first embodiment but with one or several of the following modifications:
- A power source replacing the electric generator, said source being able to be solar, wind, batteries, accumulators, a fuel cell or a combination thereof.
- One or several electric, hydraulic or pneumatic chain, steel cable, belt or synthetic cable blocks and tackles which replace the original ones.
- An infrared, Wi-Fi or Bluetooth remote control system which replaces the original radio control system as needed.

Theoscillating base 5 is particularly useful when using three or more blocks and tackles or winches. - An
electrohydraulic pump 6, the purpose of which is to send the hydraulic oil under pressure from the tank 7 to the distributor 8, formed by at least one electrovalve 9 (electrohydraulic valve) for each block andtackle 3, is also placed on the support 1. - To operate the
electrovalves 9 the support is equipped with an industrialradio control receiver 10 with: - A channel for starting/stopping the
electric generator 11 also installed in the support 1. - A channel for starting/stopping the
electrohydraulic pump 6. - And a channel for each
