System Of Horizontal Travel Lifting

Lab Catalog Supply Code: EEH0005


General presentation

Coming from applications of lifting industry, this system associates the horizontal travel and lifting functions in order to transfer of a modular load, whose values are understood between 50 to 125 daN.
Intended to be a part of the systems used in electrotechnics lab, this system has been designed to make wire by students different types of asynchronous motor starting as well as a logic control.
It is built around an electrical hoist with a capacity of 125 kg associated with an electrical cabinet integrated to the whole. It answers the securities norms in force.

Teaching objectives

  • Mono speed asynchronous motor starting.
  • Bi-speed asynchronous motor starting.
  • Variation of frequency of the asynchronous motor.
  • Logic control of the brake in lifting mode, safety management.
  • Control of measurable sizes of the installation: absence or presence of voltage (system able to be used for the electric security clearance).
  • Commissioning and inspection of the good running after wiring realization.
  • Maintenance and control of the system (thermal relay, control of the travels ends).

Technical specifications

Structure:

  • Mechanically welded Frame.
  • Working area protected by a wire fencing.
  • Access to the load by a door (with closing electric contact and key locking) located on the frame.

Lifting mechanism:

Bi-speed electric hoist with chain with nominal capacity of 125 kg, mounted with electromagnetic brake for lack of energy.

  • Lifting motor: 850W, 400V three-phase, bi-speed.
  • Horizontal travel motor: 400V three-phase, bi-speed.
  • Lifting linear speed : 2 and 8 m/mn.
  • Horizontal linear speed : 5 and 20 m/mn.
  • 4 travel ends mechanics.

Horizontal axis: left and right

  • Vertical axis: high and low.
  • Load: 8 kg modular metallic masses with 11 additional elements of 10 kg, easily removable.

Control part:

  • The electrical cabinet is full part of the system. It receives the bearing plate wired by the student.
  • It consists of two distinct zones:

Cableman Area:

  • Area receiving receives the bearing plate wired by the student.
  • A fastener device and connectors allows a quick assembly of the bearing plate wired by the student.
  • The buttons and indicators are fixed on the door and are connected to the bearing plate by a fast connector.

Power supply Area:

This second area concerns the power supply of the electrical cabinet. It is already wired and the student doesn’t have an access to it.
It includes:

  • An alternative 24V power supply.
  • A 3*400V+N+T power supply protected by a 30 mA differential circuit-breaker.
  • One security logical building block.
  • One security limit switch on the door that conditions the power sequencing of the bearing plate. This security can be inhibited permitting to make measurement exercises or electric authorization.
  • The power sequencing buttons and lights.
  • A main switch.
  • An electric power supply by three phased normalized connector 3*400V+N+T 16A.

We propose, in option, several kits of components allowing the student to realize the wiring of this bearing plate ,:

  • Lot of material to wire version direct starting on the 2 axes.
  • Lot of material to wire version speed driver.

All these components are available in cabled version on removable bearing plate

General features of the system:

  • Measurements: length: 2440 mm, width of the basis: 620 mm, height 1630 mm.
  • Weight: 300 Kg.
  • Electric power supplied : 3 x 400 V+T+N – 16 A.

Feature of the confinement casket:

  • Dimensions (L x w x h) out all: 320 x 650 x 1000 mm.
  • Dimensions of the wiring zone: width: 600 mm, height: 800 mm
