causing the safety factor is small

 broken rope accident

     Accident is the broken rope hoisting rope or hoisting rope breaking weight loss caused by the accident . Broken rope is a common one accident. Broken rope pull off mostly overloaded lifting rope ; ceiling switch failure caused from excessive volume pull off the rope ; bias caused by pulling the rope hanging oblique squeezed off ; or because of the continued use of the rope over the standard retirement caused by broken rope .

     In addition, due to the lifting wire rope buckle fracture caused by such accidents are very common. powered pallet trucks  with Shengkou rope buckle fracture mainly because inappropriate choice of specification , causing the safety factor is small ; Shengkou angle caused by too much or lifting its tension exceeds its limit and breaking pull off ; or rope buckle with heavy angular plus gasket between unprotected edges cut the rope caused by heavy buckle . Hoisting rope breaking caused mainly due mostly lifting angle is too large (> 120 °) so that the tensile strength exceeds the limit while hoisting rope to pull off .

     Hanging crane fall accident occurs mainly in the lifting mechanism extract winding system , in addition to rope off , decoupling, off the ropes and off the hook , but each hoisting rope is fixed at both ends is also very important , such as safety rope on the drum circle number is guaranteed over three laps , rope wedge plate fixed or fixed structure on the reel is safe reasonable. Another rope off the tank, off the wheel accidents also cause loss accident.
