When using two or more hoists lifting a device, how to operate? A: 1, two and two or more of the chain hoist when lifting the same weights hsvt chain hoists, the weight should not exceed the weight of each chain hoist from the weight allowed. 2, the weight determined under the center of gravity of the situation clear shz chain hoists, chain hoists can determine the appropriate setting based on their location and load calculations. How dimensional chain hoists insurance? A: 1, after use should be cleaned and coated with anti-rust gourd oil Shanghai Yan chain hoists, stored in a dry place. 2, maintenance and repair should be compared with those who were familiar with the hoist mechanism to prevent the performance of the machine do not understand the principles of free disassembly. 3, gourd after cleaning and maintenance, load test should be carried out to confirm the work, reliable braking can be delivered. Brake friction surfaces must be kept clean. Brakes should be inspected regularly part to prevent brake failure occurred since heavy fall phenomenon. 4, lifting chain open welding can not be welded, can only be replaced with new chain. If welding, chain performance different from before, fragility, easier to break. Routine inspection and maintenance hoists caveats 1. Check whether the lifting chain hoists excessive wear, corrosion, deformation and external damage. 2. Check that all rotating parts chain hoists rotation is not flexible fasteners loose. 3. Check the wear and deformation hook hook should be free of cracks, acute angle, burr chain hoists, corrosion, warping and twisting and other harmful defects. 4. lifting chain hoists should use frequently applied lubricant, dirt and other debris should glue to avoid lifting the sprocket and deposited into the recess, the impact of political engagement. 5 Use the completed chain hoists should be stored in a dry place for long-term placement should not have the proper protection and proper. Must be maintained between 6 and hoists transmission parts should be regularly greased brake friction surfaces clean and free of oil, in order to ensure reliable braking performance. 10t chain hoists, chain hoists, Shaanxi, Xinyu Xinyu lifting provided by Crane Co.
