lift hoist accident prevention squeeze

Rope hoist accidents and prevention of extrusion has the following three conditions:
   In the first case, the lift hoist body and fixtures, squeezed between buildings. The accident occurred in the operation of the lift hoist and the lift hoist or rotate around between fixtures. As of the end beam bridge lift hoist uprights with the surrounding buildings, between the wall, tower lift hoists, mobile lift hoists rotates its tail and other facilities squeezed between the accident. Accidents are due to a smaller space, the victim dead in the driver's field of vision, or lack of observation of the driver caused. Therefore, the lift hoist and the need for proper distance between fixtures, at least 0.5m spacing, operation prohibition was adopted.
   Second case, spreader, lifting heavy objects and surrounding fixtures, squeezed between buildings. In this regard, first of all should be reasonable decorating the venue, place heavy objects. Should be properly stacked cargo clearance, a huge component and easy rolling and tipping over of the goods to be stacked reasonable, easy to handle.

Second, we should choose the lever hoist and rigging spreader goods, bundled and hanging reasonably avoid spinning in the air or off. Prohibits direct hand dragging heavy rotation, according to the original signal commanding officers commanding lifting program.
  The third case, lift hoists, lifts itself squeezed between the structure accident. Such as inspection, maintenance personnel and other components of the lift hoist turntable squeezed between the accident. Building material hoists to lift more problematic in the main protective device is incomplete, without rising limiter, no protective railings or no protective doors. Protective measures are: the position to properly manipulate the hoist; no closed cage, which channel should be closed to extraordinary; entrance channel should be set up protective railings; overhaul close to the upper limit device, pay attention to prevent head-banging; bottomless pit work , pay attention to the bridge box and counterweight falls, to avoid accidents.
