Yale ITG SR Spark Resistant Chain Hoist with Built-in Geared Travel Trolley
Similar to the Yalelift 360 SR chain block, but with and integral geared (hand chain driven traverse) travel beam trolley as opposed to the standard hook suspension. The advantage of this built-in design rather then hooking the chain hoist in to the trolley suspension eye of a manual trolley, the hoists headroom (bearing point of wheels, to raised hook of the hoist unit) is reduced, allowing more versatility in low headroom applications where space is precious or restricted. There are 2 main disadvantages to the trolley being in-built, which are; the hoist and trolley must be handled and installed as a single piece, which means that the trolley-hoist combination would be heavier to install than a trolley alone, which the hoist could then be hooked in to afterwards. The second dissadvantage being that with an permanently fitted trolley, the hoist could not then be used for other applications, such as hooking in to beam clamps. If your preference is a seperate hoist and trolley, then the Yale HTP / HTG SR beam trolley will probably be of interest.
This product is provided with the following for extra spark protection:
- Stainless steel hand chain
- Zinc plated load chain
- Units completely corrosion resistant
- Bronze-plated suspension and load hooks
- Solid bronze trolley wheels
- Rubber Buffers
- Chain containers
Spark Resistance
In nearly all industrial areas, there are workplaces which need to be protected against explosions. 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 chain hoists helps to make the workplace a safer environment.
Corrosion protection
- Corrosion starts on the surface of components due to environmental influences. This affects the mechanical properties of the components, e.g. breaking strength and total ultimate elongation.
- Many components are supplied in black (unmachined),bright (machined) or painted condition.
- This offers certain protection but doesn't prevent corrosion
- With the application of a protective coating, the onset of corrosion can be reduced and delayed, thus extending the service life of the treated components.
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.
MEDIUM (Zone 1/21 & 2/22)
ATEX II 2 G Ex h IIB T4
ATEX II 2 D Ex h IIIB T135°C Db
- Unit special coated.
- Load chain galvanic zinc-plated, stainless steel hand chain.
- Top hook and load hook copper plated.
- Trolleys special coated with buffers.
- Bronze trolley wheels.
- Brake with cooling element
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
- Chemical industry
- 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
- Pharmaceutical industry
- Refineries
- Recycling companies
Here we have a geared travel manual hand chain hoist for use in a Zone 2 environment where there is a risk that a spark could ignite explosive gasses in the atmosphere. Check Yale specification or contact us to ensure this hoist meets your requirements. This is a quality product at a good price, only achievable though utilising an existing Yale design.
