③ balance hanging crane known as balance, it is the use of four-bar linkage principle makes load and the counterweight constitute a balanced system, you can use a variety of spreader flexible and easily lifting loads in three-dimensional space. Balanced crane lightweight and flexible, and is an ideal lifting small items of lifting equipment, has been widely used in factory floor machine loading and unloading, inter-process, automatic line, production line of the workpiece, lifting sand box, parts assembly, and overload limiter technology stations, docks, warehouses and other occasions cantilever crane overload limiter installation requirements are important parts jib cranes and other lifting equipment, jib cranes for running a great help. Cantilever crane is a crane, hoist rings in the construction industry to use more, with some security risks, when used to pay attention to safety, rail crane, preferably install some protection. Technical requirements cantilever crane overload limiter installed as follows. ① mechanical overload limiter integrated error should not exceed 8 percent, crane turntable, electronic overload limiter integrated error should not exceed 5%. When ② when the load reaches 90% of rated capacity weight, should be able to alert of an alarm signal. After ③ Lifting overload limiter settings, it should be based on their performance and adjust or calibrate precision, when from the weight of more than nominal weight, lifting can automatically cut off the power source, Liling crane and send warning signals prohibitive. ④ bridge type cranes, railway cranes, portal cranes, overload limiter should be installed; tower cranes, lifts and electric hoist can be installed according to actual needs. Running jib cranes and other lifting equipment must be in accordance with the rules, you can not violate the operation, otherwise it will have serious consequences, for some protection devices installed must meet the corresponding technical requirements for the job.
