Definitions

  • the invention relates to a hoisting winch slide system used in machines with folding booms or telescopic booms.
  • the invention particularly relates to a slide system that enables the high lifting capacity hoisting winch to be mounted on a machine with a folding boom or a telescopic boom without the need for shortening the jib boom length, eliminating the mounting space constraint.
  • a conventional folding boom machine basically comprises a tower (100), a main boom (200) connected to on the tower (100), the folding main boom (300) connected to the main boom (200), the hoisting winch (400) connected under the folding main boom (300) and the jib boom (fly jib) (500) attached to the end of the folding main boom (300).
  • the aforementioned jib boom (500) is independent from the main machine and it is demountable.
  • the said jib boom (500) also called the second folding boom, becomes compact by folding under the main folding boom (300) in the driving configuration.
  • the hoisting winch (400) is usually mounted under the folding main boom (300) in machines with folding booms and remains fixed where it is mounted, as seen in Figure 1. Due to the compact nature of folding boom machines, there is not much space between the jib boom and the hoisting winch in the driving configuration. In other words, the mounting space is limited. This causes some problems. The first of these problems is the winding of the rope on the cylindrical body of the hoisting winch. As the lifting capacity of the hoisting winch increases or the length of the rope wrapped around the body gets longer, the diameter of the winch's body increases. Due to the limited mounting space in folding boom machines, there are limitations in the selection of hoisting winch. Hoisting winch selection depends on the lifting capacity of the folding boom machine and the maximum boom height. When it is desired to use a hoisting winch with a high lifting capacity, will take up more space, because the diameter of the drum of hoisting winch will increase.
  • the second solution method is to mount the folding boom machine on a longer transporter truck without shortening the jib boom. In this way, both a high lifting capacity hoisting winch can be used and the lifting height of the folding boom machine is not compromised.
  • this solution method due to the fact that the transporter truck on which the folding boom machine is mounted is too long, maneuverability becomes limited. This makes it difficult to enter and exit narrow areas; therefore it limits the usage areas of the folding boom machine.
  • the jib boom operates as an external additional boom and can be dismounted and transported externally at any time.
  • the jib boom is transported externally (for example, with a different carrier vehicle), this way a high lifting capacity hoisting winch can be used and at the same time, it is not necessary to extend the length of the carrier truck on which the folding boom machine is mounted.
  • the crane can easily enter and exit narrow spaces, and the folding boom crane can reach its maximum height capacity since the jib boom is not shortened.
  • the jib boom is transported externally, a great loss of time occurs and the operating costs of the folding boom machine increase. For this reason, in the known state of the art, a need has arisen for a system that eliminates the problems mentioned above, by allowing the high lifting capacity hoisting winch to be mounted on the folding boom machine.
  • the present invention relates to a hoisting winch slide system that eliminates the disadvantages mentioned above and provides new advantages to the related technical field.
  • the main aim of the invention is to provide a slide system that allows the high lifting capacity hoisting winch to be mounted on a folding boom or telescopic boom machine without the need for shortening the jib boom length and eliminates the mounting space constraint.
  • the aim of the invention is to enable machines with folding booms or telescopic booms to be mounted on a compact carrier truck, thus enabling the carrier truck to have better maneuverability in tight spaces.
  • Another aim of the invention is to reduce the curb weight of the vehicle, by means of the carrier vehicle having a more compact structure.
  • Another aim of the invention is to slide the hoisting winch sideways or backwards during transportation, to ensure that the height of the folding boom or telescopic boom machine in the transportation configuration is lower than the normal machines and to provide fuel saving for the carrier vehicle.
  • the invention relates to the hoisting winch slide system, which allows the hoisting winch connected to the main boom, which provides for lifting of the load in the folding main boom in machines with folding booms or telescopic booms, to be mounted on the machine with folding boom or telescopic boom without the need to shorten the length of the jib boom connected to the end of the folding main boom
  • the system comprises,
  • Figure 2 shows the slide system of the invention in the demounted state.
  • the slide system comprises an upper rail (10) connected to the bottom of a folding main boom (300), the double acting hydraulic cylinder (20) which is connected to the bottom of the upper rail (10) at one end and moves the hoisting winch (400) sideways or backwards, a cylinder connection lug (30) which is connected under the top rail (10) at one end and connects the double acting hydraulic cylinder (20) from the other end to the side wall of the hoisting winch (400) and enables the hydraulic cylinder (20) to push or pull the hoisting winch (400), a slide shoe (40), which is connected to the lower part of the hoisting winch (400) and slides within the upper rail (10) and moves the hoisting winch (400) within the upper rail (10), the motion sensor (50) that controls and commands the movements of the hoisting winch (400).
  • the upper rail (10), which forms the main structure of the slide system of the invention, is preferably connected to the bottom of the folding main boom (300) by welding method. There are slide channels (11) on the said upper rail (10).
  • two double-acting hydraulic cylinders (20) are fixedly connected under the upper rail (10) from one end facing each other.
  • the said double-acting hydraulic cylinders (20) enable the hoisting winch (400) to be moved sideways or back and forth.
  • the other end of the double-acting hydraulic cylinders (20) is movably connected to the cylinder connection lug (30), which is connected to the side wall of the hoisting winch (400) in order to move the hoisting winch (400).
  • the said cylinder connection lug (30) is connected to the side wall of the hoisting winch (400), and enables the hydraulic cylinder (20) to push or pull the hoisting winch (400), by connecting the double-acting hydraulic cylinder (20) from the other end to the side wall of the hoisting winch (400).
  • Slide shoes (40) are connected at the lower part of the hoisting winch (400) by means of fastening elements.
  • the said fastening elements are preferably bolts.
  • the said slide shoes (40) enable the hoisting winch (400) to be moved within the upper rail (10) by sliding in the upper rail (10) by means of the slide channels (11) on the upper rail (10).
  • the said motion sensor (50) activates the operating functions of the hoisting winch (400) by sending a signal to the computer-controlled system of the folding boom and telescopic boom machine when the hoisting winch (400) is brought to its operating position. If the hoisting winch (400) is not brought to the operating position correctly, the motion sensor (50) detects this and does not activate the hoisting winch (400). This ways, accidents caused by operator errors are prevented.
  • the motion sensor (50) also checks whether the hoisting winch (400) and the machine with folding boom and telescopic boom are brought to the transport position (driving position) correctly and warns the operator by means of an audible and visual signal.
  • the hoisting winch (400) is shown in the transport/drive position in Figures 3 and 4. In this position, the hoisting winch (400) has been shifted to the side by means of the slide system, which is the subject of the invention, and a space has been provided for the jib boom (500) connected to the end of the folding main boom (300) to be folded, and the machine with a folding or telescopic boom has been made ready for transportation.
  • the hoisting winch (400) cannot be used in this position.
  • the operating position and driving position of the hoisting winch (400) are controlled by means of the motion sensor (50), and it limits its use outside the operating position for safety reasons.
  • the hoisting winch (400) In the driving position of the vehicle, the hoisting winch (400) is shifted to the side with the slide system, which is the subject of the invention.
  • the motion sensor (50) checks whether the hoisting winch (400) is shifted sideways. After approval is given, the jib boom (500) can be folded under the folding main boom (300) and the folding boom machine is ready for the driving position. In order to bring the folding boom machine to the operating position with the hoisting winch (400), the jib boom (500) is opened first and brought to the operating position.
  • the hoisting winch (400) is shifted sideways to bring it to its operating position by means of the slide system.
  • the motion sensor (50) allows the hoisting winch (400) to operate after confirming that the hoisting winch (400) is in its operating position.
  • Figure 5 shows the position of the hoisting winch (400) in its operating position. In this position, lifting and lowering can be performed by using the hoisting winch (400).
  • the slide system of the invention can be mounted in such a way that the hoisting winch (400) can slide forward and backward, depending on the capacity and model of the machine with folding boom or telescopic boom.
  • the operating principle of the slide system which is the subject of the invention, is the same as the sideways shifting process mentioned above, with the only difference being that the hoisting winch (400) is shifted forward or backward by means of double-acting hydraulic cylinders (20).
  • the sliding process is controlled by the motion sensor (50).
  • the slide system according to the invention is generally applied in telescopic boom machines.
  • the hoisting winch (400) is in the transport/driving position, and the hoisting winch (400) is shifted backwards with the slide system, which is the subject of the invention.
  • Space is provided for the jib boom (500) connected to the end of the main boom (200) to be folded under the telescopic boom.
