Laboratory Stand “4-Layer Elevator Trainer”

1. Product overview

1.1 Overview This equipment has an open-type structure, with a car platform sill that features a double door design. Its transparent design allows clear observation of the internal structure of the elevator, enabling hands-on activities that help students thoroughly understand and master the basic structure and movement principles of elevators. It resolves issues related to solely theoretical teaching, providing a safer alternative to visiting original elevators where comprehensive understanding of the internal structure and operational process may be challenging.

The design of this training equipment is reasonable and adheres to international dimensions. It can be used for training students in electric skills, installation technology, fault analysis, and also for skills operation training and project design of subject experiments, covering basic, professional, and integrated skills in electrical and other relevant fields.

1.2 Characteristics

1. Adopts an industrial aluminum framework, with a transparent structure design and an open-type interface, consisting of original elevator components. It is equipped with heavy-duty universal wheels with brakes for easy movement.
2. The mechanical structure and system form are similar to those of an actual elevator, allowing simulation experiments that mimic real elevator actions, providing students with a realistic operational experience.
3. The auto-door switch uses a geared motor, allowing students to master the functional characteristics of each component, contributing to a systematic understanding.
4. Provides detection signals, control actuators, and display devices for modern elevator control functions. Detection signals include outbound signals, internal select signals, flat bed signals, location detection signals, car platform sill door open and close location signals, car platform sill anti-pinch protection signals, up/down limit protection signals, etc. The elevator car platform sill can move up and down, and the door has protective functions for switching and limiting. It also displays floor level, moving direction, and responds to outbound/internal select signals for each floor location.
5. Electrical control consists of Siemens S7-200 PLC, Siemens transducer, constant magnetism low-speed synchronous motor, decoder, and other related components.
