Description

Technical Field

[0001] This utility model relates to the field of building materials, and in particular to a safety lifting device for building materials. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of buildings. During construction, materials need to be lifted from the ground to higher floors to facilitate workers' use in construction.

[0003] Chinese Patent Publication No. CN220098406U discloses a safe material lifting device. Addressing the problem that existing support plates for placing items are only a single plane without any surrounding obstructions, posing a risk of materials falling during lifting and creating safety hazards, the patent proposes the following solution: a base and a bracket, with the bracket fixedly connected to the top of the base, and a placement rod fixedly connected to the top of the base. However, existing devices still have some shortcomings. Current material lifting devices typically lift materials to a suitable height, and then workers pull the materials to the floor. However, this pulling process is prone to danger and accidents. Therefore, we propose a safe lifting device for building materials to solve the above problems. Utility Model Content
