Lifting System

Lifting System

General introduction of:

• This system permit to wire by the students different types of asynchronous motor starting.
• It must be manufactured around an electric hoist of 125 kg capacity with a containment cabinet integrated to the whole.

Frame :

• Welded stainless steel.
• Protection of the working area by a safety grid.
• Access door to the load equipped with a security end stroke sensor and a lock key.

Teaching objectives

• Mono speed asynchronous motor starting,
• Bi speed asynchronous motor starting,
• Frequency variation of the asynchronous motor,
• Logic control of the brake in lifting mode,
• Safety devices management,
• Installation sizes control,
• Presence or not of voltage (system capable to be used for the electric authorization),
• Installation and verification of the good working after wiring,
• Maintenance and setting of the system (thermal relay, adjustment of the end stroke sensors).

Technical specifications

• Electrical bi-speed hoist with chain, 125 kg capacity with brake.
• Bi-speed lifting Motor 200 W - 400 V 3 phase.
• Linear speeds: 2 m/mn and 8 m/mn.
• Working end stroke: high and low.
• Out stroke: high and low (forcing by key button).
• Load constituted of a metallic mass of 15 kg and 11 modular elements of 10 kg.

Control part:

• 1 wired platen including all the components for a direct starting
• 1 wired platen including all the components with speed driver.
• The containment cabinet also include a differential circuit breaker, a end stroke security sensor on the door of the cabinet and one logic block security device that allows the electricity supply of the platen.
• A fast fixing device and connectors permit a fast installation of the platens wired by the students

• Dimensions (L x w x h) (basis) : 1000 x 1000 x 2300 mm.
• Power supply 3 x 400 V+T+N. 16A.
