What should be considered when using a speed differential device to protect goods

When conducting high-altitude maintenance operations, electric power maintenance personnel often use fall arresters to protect themselves. In addition, some factories, warehouses, and other places also use Guanhang fall arresters to prevent goods from falling during cargo lifting. When using Guanhang fall arresters to protect goods, users need to be careful to avoid misusing the fall arresters and causing heavy objects to fall.

When using a speed differential device to protect heavy objects, it is essential to first estimate the weight of both the heavy object and the lifting machinery. Based on the combined weight of the heavy object and the lifting machinery, a speed differential device of an appropriate tonnage should be selected. Subsequently, the user must suspend the speed differential device directly above the heavy object to prevent it from falling and being locked by the device, causing it to swing back and forth and potentially hitting nearby objects and causing damage. After selecting the appropriate suspension position for the heavy object, the user must also choose a suspension point that is structurally stable, resistant to deformation, has a high load capacity, and features blunt edges. This is to avoid deformation or even fracture of the suspension point when the speed differential device locks the heavy object, which could result in the heavy object falling.

By using the speed differential device correctly, users can ensure that the Guanhang speed differential device can lock up in time when heavy objects fall, preventing injuries to nearby workers caused by the falling objects.
