Car-A unit for passenger elevator, consisting of a car frame, a car bottom, an enclosure and a car door. Handrail-(1) A moving belt installed on the top of the escalator handrail for passengers to hold. (2) A ribbon used as a support. Armrest frame-a bracket usually made of rubber, which is installed at the joint of the armrest and the armrest belt to prevent the fingers of the passenger from being caught in the gap between the armrest and the armrest. Holding brake-An electromechanical device that prevents the elevator from moving when the elevator car is stationary and the motor is in a de-energized state. In some forms of control, it brakes the elevator when the motor is powered off. Brake shoe-the moving part of the brake, the surface is a friction surface. When the brake drum pushes it, it will brake the elevator in the leveling state. In some forms of control, it brakes the elevator when the motor is powered off. Layout drawing-a drawing drawn to scale, showing the elevator plane, shaft elevation, machine room space, relative size and location of installed equipment. Guide rail-A T-shaped steel rail whose surface is machined.It is installed vertically in the hoistway and is used to guide the movement of the elevator car or counterweight. Guide wheel-Use a rolling wheel instead of a guide shoe to slide and guide on the surface of the guide rail. Brush-usually made of carbon or graphite, used to connect the rotor of the motor and generator.It passes current to the stator. Counterweight-used to balance the weight of the car plus approximately 40% of the rated load. Generator-A device that converts chemical energy into electrical energy (usually direct current). Handrail-the part of the side of the escalator above the rungs, which includes the skirt board, the inner board, the cover board and the handrail. Specification-a set of standards for the design, manufacture, installation and maintenance of elevators, dining ladders, escalators and moving walkways. Specifications-documents detailing the plan, materials, dimensions and all other requirements and purposes of each equipment to be installed.
