Which 100 are included in the safety device of the lift

When the elevator is operating, it is necessary to have safety devices to protect, speed limiters, buffer springs, upper and lower limiters, upper and lower limit limiters, safety hooks, emergency stop switches, cage doors, protective fence door interlocking devices, floor access doors, communication devices, ground entrance protective sheds, and broken rope protection devices. I have bought the elevator of Aolong Machinery Equipment before, their lifting equipment, these safety accessories are available.

The following safety devices are in place:

1) Protective shed at the feeding port;

2) Floor safety door, hanging basket safety door;

3) Broken rope protection device and anti-fall device;

4) Safety docking device;

5) lifting weight limiter;

6) upper and lower limiters;

7) Emergency power-off switch, short-circuit protection, over-current protection, leakage protection;

8) signaling device;

9) Buffer.

1. Speed limiter.

In order to prevent the cage of construction elevator from speeding or falling, a kind of safety device is divided into two kinds of one-way type and two-way type, one-way speed limiter can only play the role of speed limiting along the direction of the cage descending, and the two-way speed limiter can play the role of speed limiting along the upper and lower directions of the cage. The speed limiter shall be tested for performance within the specified period.

2. a buffer spring.

The buffer spring is installed on the spring seat connected with the foundation frame, so that when the falling accident occurs in the cage, the impact of the cage is reduced, and at the same time the soft contact between the cage and the counterweight is guaranteed to be in soft contact when it is lowered and landed, and the impact of the cage and the counterweight is slowed down.

3. Upper and lower limiters.

The device that is set up to prevent the cage from exceeding the required stopping position when going up and down, or continuing to go up or down due to the driver's misoperation and electrical failure and other reasons to cause accidents, is installed on the cage and the guide rail frame, and the limiting device is made up of a limiting bumper block and a limiting switch.

4. Upper and lower limit limiters.

The upper and lower limit limiter is when the upper and lower limit does not work, when the cage runs beyond the limit switch and overstep, it can cut off the power supply in time to stop the car. The limit limit is a non-automatic reset type. After the action, the car can only be restarted by manual reset.

The limit stoppers are mounted on the car and rail frames. (Override refers to the specified safety distance between the limit light and the limit switch).

The following safety devices are available:

1.Protective shed at the feeding port;

2.Floor safety door, hanging basket safety door;

3.rope breakage protection device and fall arrester;

4.safety docking device;

5.lifting capacity limiter;

6.upper and lower limiters;

7.Emergency power-off switch, short-circuit protection, overcurrent protection, leakage protection;

8.signalling devices;

9.Bumper.

4. Safe use of construction hoist.

1.Speed limiter, buffer spring, upper and lower limiter, upper and lower limit limiter, safety hook, emergency stop switch, cage door, protective fence door interlocking device, floor access door, communication device, ground entrance protective shed, broken rope protection device.

The lift has the following safety devices:

Door lock safety device: When the door is not closed or locked, the lift cannot be operated.

Fall safety device: Once there is an abnormality in the lift system, immediately cut off the power supply to prevent the lift from falling.

Limit switch safety device: install a limit switch on the carriage or chassis position, when the compartment descends to a certain height or rises to the highest position, the compartment and chassis will automatically stop.

Safety hook and buckle safety device: A safety hook is installed above the carriage or on the support frame, and once the electric lift has an accident, they will make the carriage stay in a position with safety protection.

Buffer safety device: The buffer is usually installed at the end position of the erection of the electric lift, which is used to slow down the movement of the electric lift and prevent impact.

Chassis stall protection device: When the chassis is moving, if the chassis speed is abnormal or stalled, the system will immediately cut off the power supply to ensure the safety of the occupants.

Emergency stop device: An emergency stop device is installed above the carriage or chassis, and in the event of an emergency, the rotary button makes the carriage or chassis stop immediately.

Temperature protection device: The elevator is equipped with a temperature sensor inside, and when the internal temperature of the electric lift exceeds the set value, the system will cut off the power supply to prevent accidents.

Clause. 1. Anti-fall safety device.

The fall arrester is an important safety device for construction hoists. When the speed of the cage descent exceeds the quota speed, the action of the fall arrester will automatically open, so that the car will not go down. It is inspected once a year and scrapped every five years.

Clause. 2. Buffer spring.

There are four buffer springs at the bottom of the construction hoist cage to reduce the impulse on the cage when the cage is lowered.

Clause. 3. Upper and lower limit switches.

It is installed to prevent the car from going up and down over the required position, and it is installed due to accidents caused by the driver's misoperation or the failure of electrical equipment to continue to rise or fall. The upper and lower limit switches must be self-reset. The installation position of the upper limit switch ensures that after the cage triggers the limit, the safety distance of the upper part shall not be less than meters.

The override distance to the upper limit is meters. After its action, it must be manually reset before the cage can be operated.

Clause. Fourth, the upper and lower limit switches.

If the upper and lower limits fail, the elevator continues to go up or down, exceeding the overrun distance, the upper and lower limit limits will be triggered, and the power will be forcibly cut off, forcing the ladder cage to stop running to ensure safety.

Clause. 5. Safety hook.

If the upper limit and upper limit fail for some reason, it is set to prevent the ladder cage from continuing to rise. The safety hook is the last safety device installed on the upper part of the Zen Destroyer cage.

Clause. 6. Mechanical interlocking device.

In order to prevent the safety device of the hanging gantry and the bottom gantry from not closing and the cage running. If the cage door is not closed, the elevator cannot operate.

Clause. 7. Emergency stop switch.

In case of emergency, the driver presses the stop and emergency stop switch in time, and the elevator stops running. The emergency stop switch must be a manual resuming punch device.

Clause. 8. Floor access door.

The stop position of the cage on each floor, the safety protection door at the unloading platform. The door is required to be open to the inside of the floor and the closing latch is to be outside. As long as the cage is exited, the protective door must be closed.
