Construction elevators, also known as construction elevators, outdoor elevators, are commonly used in the building of manned, cargo construction equipment. In order to protect the safety of the user, set up a variety of safety devices, understand these safety devices. If necessary, you can save your life! Here's vertical man lift for sale.
1. Buffer device
The buffer spring of the construction lift is installed on the spring seat connected with the base frame. When the hanging cage falls, the impact force of the hanging cage is reduced. At the same time, the hanging cage and the counterweight are flexibly contacted when they fall to the ground, and the vibration of the hanging cage and the counterweight is slowed down.
2, electrical safety switch
Electrical interlock limit switch; construction elevator travel switch, also known as limit switch, is used to control the travel of mechanical equipment and limit protection, according to the moving parts of the travel position switch circuit electrical appliances. Principle: One group generally open, one group usually closed.
3. Mechanical interlocking device
Mechanical interlocking devices should be used in conjunction with electrical safety switches. When people and goods enter and exit, when the door is not closed or not tightly closed, the cage will stop working. When the elevator equipment is working, the door opens and the cage control circuit is disconnected. The cage stopped working.
4, anti falling safety device
An anti-fall safety device is an essential safety device for construction elevators. It is mounted in a cage. When the cage height drops due to the fault, the anti-fall safety device will brake the cage smoothly within a certain distance to prevent the cage from falling and ensure the safety of personnel. A fall test must be conducted quarterly to see if the fall preventer's detection date has expired.
6, the construction of elevator overload protector
The overload protector of the construction lift is installed at the connection between the car and the drive plate to sense the weight in the car. When the device is overloaded, it will alarm and cut off the circuit and cannot start. And the weight signal is converted into a weight limiter.
7. Safety hook
When the cage is lifted to the top of the rail frame safety protection facility, the cage shall be safely hung on the guide rail to prevent the cage from falling apart from the rail frame or the gear of the safety output end of the cage.
8. Emergency stop switch
When THE CAR IS IN EMERGENCY FOR various REASONS, the driver can press the emergency stop switch at anytime to make the car stop running.
