Cantilever crane overload limiter technical requirements for installation overload limiter is an important accessory jib cranes and other lifting equipment, jib cranes for running a great help. Cantilever crane is a crane, use more in the construction industry, with some security risks, Xilinhot electric cranes, pay attention to safety when used, it is best to install some protection. Technical requirements cantilever crane overload limiter installed as follows. ① mechanical overload limiter integrated error should not exceed 8 percent, 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. ③ after lifting machinery set overload limiter, small electric hoist, should be based on their performance and accuracy adjust or calibrate, when from the weight exceeds the nominal weight, mini electric hoist, lifting can automatically cut off the power source, and issued ban of the alarm signal. 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, household electric cranes, otherwise it will have serious consequences, for some protection devices installed must meet the corresponding technical requirements for the job. 1.3 hoisting rope hoist section 1.3.1 can not have rust and yarn breakage; hook surface can not have cracks. 1.3.2 Lifting pulley block to be flexible operation, no jam phenomenon.
