There are many types of elevators and various structural forms. The common machine room exchange passenger elevator machine. The main components of the elevator system are in the machine room, hoistway, hall door, and pit. The unit used by the car for carrying is composed of the car frame, the car bottom, the fence and the car door. An electromechanical device that prevents the elevator from moving again when the elevator car is at a standstill and the motor is in a power-off state. In some forms of control, it will stop the elevator when the motor is de-energized. The surface of the moving part of the brake shoe is the friction surface. When the brake drum pushes it, it will stop the elevator in the leveling state. In some forms of control, it will stop the elevator when the motor is de-energized. Layout drawing A drawing drawn to scale, showing the elevator plane, hoistway elevation, machine room space, relative size and the location of the installed equipment.

Guide rail and guide wheel Guide rail is a T-shaped steel rail whose surface has been machined. It is installed vertically in the hoistway and used to guide the movement of the elevator car or counterweight. The guide wheel uses a rolling wheel instead of a guide shoe to slide and guide on the surface of the guide rail. Brushes are usually made of carbon or graphite and are used to connect the rotor of the motor and generator. It transmits current to the stator. The counterweight is used to balance the weight of the car plus about 40% of the rated load. The side of the escalator is the part above the steps, which includes the skirt board, the inner side board, the cover board and the handrail. Handrail is a moving belt installed on the top of the escalator handrail for passengers to hold. Used as a support belt. The armrest frame is a bracket usually made of rubber, which is installed at the joint of the armrest and the armrest belt to prevent passengers' fingers from being caught in the gap between the armrest belt and the armrest. The fire alarm operates one or a group of equipment used to: provide a specific signal to make the elevator in normal operation immediately descend to a pre-set floor; allow firefighters or other specific personnel to use the elevator. The place where one or a group of elevators, dining elevators, freight elevators or escalators are placed in the machine room. The car top inspection box is installed on the control panel on the top of the car. When it starts, the car will depart from normal operation and will only be controlled by it to run at the inspection speed. The car operating panel is arranged in a panel in the car for operating the elevator. There are floor selection buttons, door opening and closing buttons, alarm buttons and other switches or buttons needed to operate the elevator. The car counterweight is a set of weights connected to the car in the form of a drum. In actual installation, its weight is about 70% of the weight of the car. The hoistway is a passage through which one or more elevators, freight elevators or dining elevators run. It includes the space from the pit to the bottom of the machine room or the roof. The control cabinet is used to control one or a set of equipment connected to it according to a preset program. The door machine is a device that is installed on the car to drive the door to open or close by a motor. Door lock Any kind of mechanical lock used to prevent the hall door from being opened in the elevator hall door. The action of the leveling elevator approaching the hall door sill in the leveling area. Leveling refers to the process of reaching the first floor or a parking position (the plane of the car bottom is flush with the landing door) completely automatically. One or more wheels used to wind the groove of a steel wire rope mounted on a bearing. The accompanying cable is used to connect the elevator, dining elevator or freight elevator car with its machine room or hoistway signal cable. The up and down direction of the hall door indicates the signal display device installed in the elevator hall. When the elevator is approaching the floor, the direction of the elevator is displayed. A platform for carrying passengers on a stepped escalator.
