AI Technical Summary
Existing steel profile hoisting equipment lacks a fall protection structure when hoisting long steel profiles, which makes the steel profiles prone to tilting and slipping, posing a safety hazard.
A steel profile hoisting device including a hoisting crossbeam and a fall protection mechanism was designed. The fall protection mechanism consists of a rotating hole, a rotating shaft, a steel cable pulley, a throttle, a steel cable body, a connector, a C-hook, a check tooth, a connecting rod, a check plate, a lever, a fixing plate, and a spring. Through the locking of the check tooth and the check plate, the steel cable pulley is prevented from automatically releasing the line without manual intervention, thus limiting the slippage of the steel profile.
It effectively prevents long steel profiles from tilting and slipping during hoisting, provides operators with time to retrieve the falling steel profiles, and improves hoisting safety.
