Cantilever crane parts crane boom height limiter fitting height limiter device will trip the switch and pull the strip-type structure punch combination, simple, sensitive and effective to suppress the occurrence of significant personal injury, make sure the Construction site safety. After several years of using a cantilever crane beams, the effect is significant. Structure and installation: The limit switch bolted sheet steel semi-enclosed box-like protection. Protective case with two slide seat bottom weld, punch-type brace can be moved around within the seat slide chute. At one end of the punch-style pull drilled a small hole for fixing thin rope or nylon rope. Cantilever crane slickline Viagra nylon rope used to set the height limit. Cantilever lift lifting height limiter can be installed next to the hoist can also be installed in the distribution cabinet. When installed, the thin rope or nylon rope wear firmly fixed in the hole punch style brace person end and the other end is fixed to the top of the cage. Limit switch lead connects to the distribution cabinet AC contactor. How it works: When the construction of the lift cage upward run, the small wheel on the trip switch in the punch-type brace pits - energized position. When the cantilever crane lifts a mechanical failure or operator misuse, the cage has been increased to limit the height of a small jib cranes, lifting height limit that is set at the height due to the fine wire rope hoists and beams affects punch style brace, Meanwhile, the small wheel on the trip due to switch on the external force to move hump punch style brace, the small wheel is powered from the mouth of the point position to bump, make the trip switch power off cantilever spreader, cut up the power winch motor stop operation, the cage stops running. Manual lifting height limit from the punch-type brace to make the trip from the small wheel on the switch is reset to pit bump energized position, to make the cage starts. Crank series cantilever crane has a novel structure, flexion freely, flexible operation, energy efficient features. Cantilever crane operation, pressing a button will load material lifted by bending and rotational motion of the beam, avoidance of objects within the control of the work area to maximize the working area. Gently push and pull, can attain a position in any work area. Gantry crane lifting capacity of up to 2000 kg, all using a crane hanging impossible or uneconomical place can easily use. Gantry crane can simply split into several easily transportable parts can be used in another place quickly assembled, this feature beneficial on many occasions. Trackless beam gantry crane lifting capacity of up to 2000 kg.
