■ Hoisting Motor
Motors are classified according to the potentially explosive atmospheres which are present at the place of installation. The rotor brake motors are 3 phase AC squirrel cage induction motors. The hoist motor are 2/12 pole. Type of Protection IP66, 40% ED, F protectors as standard
■ Flameproof Brake
Our brakes meet the requirement of ATEX Directive ATEX 94/CE-ATEX 95, Group II 2GDcategory, in compliance with the norms norme EN 60079-0:2006, EN60079-1:2004, EN61241-0:2006 and EN61241-0:2004. VIS brake are certificate INERIS 06 ATEX 0047/01.
■ Limit Switch
Compliant with IEC Standard, our explosion-proof limit switches are electro-mechanical devices that consist of an actuator mechanically linked to a set of contacts. When an object comes into contact with the actuator, the device operate the contacts to make or break an electrical connection.
■ Trolley Wheels
The standard wheels on EX trolley meet ATEX requirements. For off-standard applications or if the customers particularly requests for non-sparking area, brass wheels can be provided.
