Electric ladders are generally inclined, and the pedestrians who automatically walk on one end of the escalator will be automatically taken to the other end of the escalator, and the steps will be kept level all the way. Ladders are provided on both sides with handrails that move synchronously with the steps for users to hold. So what is the price of the villa escalator? Take a look at the introduction below.
Villa escalator price
The price of the villa elevator depends on many price factors such as brand, floor height, function, configuration, landing and decoration. In the international market, the price of villa elevators in the international market is the price of basic functions in the international market. For example, the price of the villa elevator with a load of 300kg and the floor of the second floor is between $ 35,000 and $ 45,000. -Including equipment price, sea and land freight and installation costs, one-year quality warranty period maintenance and repair costs and replacement parts costs; in the Chinese market, there is no exact standard to measure the price of home elevators or villa elevators, the same as above The all-inclusive quotation of the technical specifications of the villa elevator is from 100,000 yuan to 250,000 yuan, which can be described as a mixture of fish and dragons. It cannot be generalized, but customers can focus on safety.
Escalator composition
The escalator is composed of a ladder road (a modified plate conveyor) and handrails on both sides (a deformed belt conveyor). Its main components include step, traction chain and sprocket, guide rail system, main transmission system (including motor, deceleration device, brake and intermediate transmission link, etc.) drive spindle, ladder tensioning device, handrail system, comb board, escalator skeleton and Electrical systems, etc. The staircase gradually forms a staircase after horizontal movement at the passenger entrance (to facilitate passengers to climb the ladder); the staircase gradually disappears near the entrance, and the staircase again performs horizontal movement. These movements are realized by the main wheels and auxiliary wheels of the step walking along different step guide rails.
Reasons for escalator reversal
1. Electrical risk sources
Out-of-phase, open-phase, and loss of voltage of the power grid cause the motor to reverse or lack of driving force, which causes the upward escalator to reverse, especially under heavy-load upward working conditions; short-circuit, adhesion, open circuit and other failures of low-voltage components or devices, Or the safety circuit, brake control circuit, etc. malfunction, making it invalid, it cannot play the role of protection, control, stop, etc., and reverse the escalator.
1. Mechanical risk sources
The broken chain of the drive chain between the drive device and the cascade sprocket causes a reverse rotation; the chain of the drive staircase breaks the chain and causes a reverse rotation. The escalator is overloaded severely, causing the motor to run short due to insufficient torque, and the drive between the drive device and the cascade sprocket The used belt slips and causes a reverse rotation. The escalator and moving walkway suddenly break down during operation and cause an emergency stop, while the working brake cannot provide enough braking torque to cause a reverse rotation.
Precautions for using escalator
1. Hold the armrest firmly.
2. Don't stand on the level.
3. Do not stick your head or hands out of the ladder, otherwise you may hit the ceiling or the adjacent escalator.
4. Don't run and play.
5. Do not use escalators to carry goods. Baby strollers, cargo carts, etc. should use lifts.
6. Passengers who use wheel leaning and crutches should use elevators as much as possible.
7. Take care of children and the elderly.
8. The escalator will have an emergency stop button for use in case of an accident.
