What are the safety devices and controls used in a building hoist?

Building hoists, also known as construction hoists, are equipped with several safety devices and controls to ensure safe operation. These include limit switches to prevent overtravel, safety locks that engage if the hoist sways excessively, emergency stop buttons for immediate cessation of movement, overload protection to prevent the hoist from lifting more than its capacity, and interlock systems that ensure the hoist cannot operate if a safety gate is open. Additionally, there are guardrails, toe boards, and anti-fall devices to protect workers from falling. Regular inspections and maintenance are also crucial for the safe operation of building hoists.
