Technical field

The utility model relates to the technical field of lifting equipment, specifically a simple purlin lifting device.

Background technique

Purlins, also known as purlins and stringers, are horizontal roof beams that are perpendicular to the roof trusses or rafters and are used to support rafters or roofing materials. Purlins are transverse bending (usually two-way bending) components and are generally designed as single-span simply supported purlins.

In the existing technology, the purlins in the factory building are lifted by installing pulleys on the beams and then using steel wire ropes and winches.

However, the fixed connection between the pulley and the beam is more difficult. Generally, the sling is wrapped around the beam, and then the hook on the pulley is suspended from the sling to achieve the suspended installation of the pulley. Since the sling itself is a flexible structure, After the hook is connected to the sling, the pulley is prone to deflection. When lifting the purlin, it is easy to cause the purlin to rotate, which poses a great safety hazard. To this end, the utility model proposes a simple purlin lifting device to solve the above problems.
