Lift height is greater than or equal to the hand pallet truck platform should be set 2m fence

Lift height is greater than or equal to the lifting platform should be set 2m fence , fence height of not less than 1.8m. Safe distance from the fence and the lifting platform is not less than the values ​​in Appendix B .
5.4.2 Floor fence
Height greater than or equal to 2m floor or work surface should be at the wellhead platform lift access should be provided to prevent persons falling edge of the fence .
Fence height not less than 1.8m, when the horizontal movement of the fence member and the lifting platform a distance electric order picker greater than 0.5m, the height of which can be reduced with increasing distance , when the horizontal distance is greater than 2.0m, the height can be reduced to the minimum 1.1m.
Safe distance from the fence and the lifting platform is not less than the values ​​in Appendix B .
5.4.3 Fence Gate
Fencing floor or work surface Air lift table should be at the entrance is on the bench fencing door, the door is not allowed to open the lift platform direction .
5.4.4 overhaul security doors

Hoisting rope breaking caused mainly due mostly lifting angle is too large

    In addition, due to the lifting wire rope buckle fracture caused by such accidents are very common. Lifting 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 Air lift table 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.
