Push Travel option is only available on capacities less than 2000kg, over and above capacities must utilise geared travel.
Yale ATEX Beam trolley for potentially explosive environments, EX, sparkproof. Corrosion resistant with rubber buffers fitted and solid bronze trolley wheels. Options as push travel and geared travel (chain drive). Can be fitted with track clamp for locking the trolley on to the lifting beam
A beam trolley enables the exact positioning or easy traversing of large loads with either manual or powered hoisting equipment. It has excellent controlling features due to machined steel wheels mounted on prelubricated, encapsulated ball bearings.All trolleys conform to ATEX Group II, surface. Category. Zone 1. Explosion group IIB. Temperature class T4(T3)
The HTP/HTG SR beam runners are adjustable to fit a wide range of beam widths and profiles (e.g. INP, IPE and IPB). The trolley wheels are designed for a max. beam profile incline of 14%. Adjustments are made by rotating the clevis load bar which also ensure the centred positioning of the hoist in the clevis - no creeping to the left or the right. Anti-tilt and wheel fracture support devices according to DIN 15018 and the machinery directive are standard.
Optional
- Track clamp (locking device) for 500kg to 5000kg models for fixing the beam glide in a stationary position.
- Lock nuts for 500kg to 2000kg models.
- SWL up to 20 tonne SWL (20000kg)

Spark Resistance:
In nearly all industrial areas, there are workplaces where explosions are an ocurrence which needs to be protected against. Because of the great damage an explosion could cause to people, property and materials, strict legal and technical requirements are imposed. The Spark Resistant range of beam trolleys helps to make the workplace a safer environment.
Yale HTP/G - Spark resistant trolleys meet the following specifications as standard;

Yale ATEX Levels of Protection
All of Yale’s ATEX hoists meet the following standards: EN1127-1:1997; EN13463-1:2001; EN13463-5:2003, and are supplied complete with the relevant ATEX approval documentation.
Yale (Columbus McKinnon) offer three levels of protection - BASIC, MEDIUM, and HIGH.
Under directive 94/9/EC, equipment for areas with an explosion hazard are assigned to groups, categories and temperature classes. This is necessary as the requirements for equipment need not be the same for every application and for every hazard classification.
NB: It is the responsibility of the end user to identify the explosion proof classification required, NOT the hoist manufacturer or the supplier. Reference Directive 99/92/EC.

Why explosion protection?
Explosion protection for electrical and mechanical machinery is an important precautionary measure to ensure the safety of persons and all kinds of production, storage and distribution systems, when explosive mixtures of combustible gases, dusts and air may occur.
What does explosion protection achieve?
Explosion protection can mean to generally prevent the ignition of an explosive mixture. Explosion protection can also be achieved by eliminating potential ignition sources in advance, e.g. high temperatures and sparking. In many trades and industries, combustible gases, vapours and dusts are handled which have the potential to cause explosions.
Examples of explosion hazards in various industries

- Waste disposal sites
- Energy production companies
- Waste management companies
- Gas suppliers
- Metal processing companies
- Wood-processing companies
- Paint shops
- Agriculture
- Food and feed-stuffs industry
