The design of this guardrail can ensure the safety of staff when performing repairs, maintenance or cleaning the elevator pit, and can also prevent accidental falls or other injuries.
[0003] The mesh protection frame used around the existing assembled elevator pit guardrail protects the ladder pit counterweight. At the same time, the mesh allows maintenance personnel to see the ladder pit counterweight through it. When the observation mesh cover is dusty after long-term use and needs to be replaced and cleaned, the observation mesh cover can be taken out for cleaning and replacement by loosening the assembly bolts. The simple and convenient installation and disassembly of the observation mesh cover helps maintenance personnel to observe the area around the elevator pit counterweight.
[0004] However, the existing assembled elevator pit guardrail has certain limitations because the shapes and sizes of existing elevators are different, but its structure is fixed and cannot be adjusted. If the elevator is too small, it cannot be accommodated. If the elevator is too large, the guardrail needs to be constantly adjusted, affecting work efficiency. Utility Model Content
