Lifting System
General introduction of:
Lifting System
- 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
Lifting Mechanism:
- 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:
The containment cabinet is an integral part of the system and is able to receive the platen wired by the student . We propose in option different set of equipments:
- 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
General features:
- Dimensions (L x w x h) (basis) : 1000 x 1000 x 2300 mm.
- Power supply 3 x 400 V+T+N. 16A.
