Feature

■  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 motors are 2/12 pole. Type of Protection IP66, duty cycle 40%, F protectors are standard. 

■  Flameproof Brake

Our brakes meet the requirements of ATEX Directive ATEX 94/CE-ATEX 95, Group II 2GD category, in compliance with the standards EN 60079-0:2006, EN60079-1:2004, EN61241-0:2006 and EN61241-0:2004. VIS brake certificate: INERIS 06 ATEX 0047/01   

■  Limit Switch

Compliant with IEC Standards, 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 operates 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 customer particularly requests for non-sparking areas, brass wheels can be provided. 

■  Bottom Block and Hook

The 360 swivel hook is made of high-strength and high resistance forged steel, and if fitted, swiveling crossbar.  The elegant bottom blocks are equipped with protective edging around the rope opening and are provided with an anti-drop safety latch. Bronze-coated bottom blocks or load hooks on request to reduce the possibility of sparking in the event the hook strikes steel or other ferrous metal objects.

■  Rope Drum & Rope

The rope drum is designed for high safety and long service life.  Fine machining of the drum grooves minimizes wear on the rope.  Applying the high strength galvanized steel wire rope complies with safety standards.

■  Control Panel

Explosion-proof control panels are designed to reduce or eliminate the risk of explosion in hazardous environments. Body and ribbed lid are in copper-free aluminum alloy.  Neoprene seals to prevent an accumulation of explosive amounts of hazardous dust.

■  Push Button Switch (IP65) with EMS

Certified ATEX II 2 GD, our push button switch is suitable for Equipment Group II -all other explosive areas.  According to IEC 60529, the advanced features of water-proofing and dust-prevention meet IP65 standard.  With the benefits of ergonomic design, prompt action and simple operation, users make quick and good performance decisions on movements.                             

■  Overload Protection                                                 

Mechanical overload protection cuts off the power to the motor to prevent objects lifting in case of excessive overloading.
