In many areas of industry, plants are operated with potentially explosive atmospheres. Due to the very high risk to personal and other assets, extremely strict guidelines and technical requirements are in place in explosive zones. Tiger Spark Resistant products are manufactured in accordance with ATEX Directive 94/9/EC and the Machinery Directive 2006/42/EC. Our products are lightweight and durable with a proven track record.

Note: It is the responsibility of the user to identify which explosion proof classification is required, not the hoist manufacturer or supplier. 
Subsea lever hoist SS11
The original & proven subsea lever hoist – constantly developed and improved

The SS11 has been designed and developed over a number of years for use primarily in the Subsea environment. The unique design features – including the one piece construction pinion gears and Quad Cam Pawl System – and the anti-corrosion properties incorporated in this range, give it significant safety advantages over standard lever hoists, making the hoist the ideal tool for all marine and extreme applications. 

The SS11 range is suitable for use in multi-immersion applications providing the timescales, pre-use testing, maintenance and service requirements as detailed in relevant Tiger documents are strictly adhered to. 

This model includes our unique rotational inertia driven torsion switch brake and freewheeling system. This brake system was designed by our research and design team to counter known failure modes in commonly used and copied longitudinal “push-pull” mechanisms or traditional style “Weston” type brake systems used on alternative lever hoists. This Tiger brake system is now a proven design with many thousands of hours of empirical evidence as proof of design and efficiency. This design removes the need for inefficient old style longitudinal disengagement methods of pulling the brake system apart to facilitate freewheeling. This highly efficient method of operating is not only safer but easier for the operator whilst measurably increasing the brake take up efficiency rate.

Tiger uses an 8 point multi start thread pinion shaft which has also increased brake reaction times. The rotational engagement of the brake works with the direction of the load sheave creating highly efficient braking ratios – up to 50% measurable difference compared with longitudinal 4 point pinion threads.

The continued development of the SS11 range of Subsea lever hoists is evidence of Tiger’s commitment to innovation and customer satisfaction.

Professional lever hoist PROLH
The professional’s choice incorporating our patented Quad Cam Pawl design and Torsion Brake System.

PROLH lever hoists incorporate many of the advanced safety features that Tiger has developed including one piece construction pinion gears and our patented Quad Cam Pawl System.

Like the SS11 range, this model also includes our unique rotational inertia driven torsion switch brake and freewheeling system. This brake system was designed by our research and design team to counter known failure modes in commonly used and copied longitudinal “push-pull” mechanisms or traditional style “Weston” type brake systems used on alternative lever hoists. This Tiger brake system is now a proven design with many thousands of hours of empirical evidence as proof of design and efficiency. This design removes the need for inefficient old style longitudinal disengagement methods of pulling the brake system apart to facilitate freewheeling. This highly efficient method of operating is not only safer but easier for the operator whilst measurably increasing the brake take up efficiency rate. 

Tiger uses an 8 point multi start thread pinion shaft which has also increased brake reaction times. The rotational engagement of the brake works with the direction of the load sheave creating highly efficient braking ratios – up to 50% measurable difference compared with longitudinal 4 point pinion threads.

The PROLH is ideally suited for applications in the overhead transmission industry, shipyards and offshore platforms and is also suitable for underground mining use.

These units meet and exceed all the requirements within BS EN 13157: 2004+A1:2009, ANSI/ASME B30.21, AS1418.2 and SANS 1636.

Industrial lever hoist TLH 
Lightweight, compact and rugged

The TLH is lightweight, compact and of rugged construction with the handle, gear case and brake cover made entirely of pressed steel, producing strong resistance to impact damage. We use only the highest quality materials precisely machined throughout. The hoist is finished in our high quality powder coat paint offering excellent corrosion protection. This all ensures the TLH is the ideal hoist for long-term use with less maintenance and servicing costs. 

The strong impact resistant gearbox housing, complete with close tolerance fit bearings that fully support the pinion shaft and planet gears, maintains smooth revolutions whilst under load. High gear ratios keep physical effort to a minimum. This provides maximum mechanical efficiency. 

The user friendly heavy duty end stops make it easy for the operator to position the chain whilst “freewheeling” but most importantly gives complete compliance to all known standards. 

These units meet and exceed all the requirements within BS EN 13157: 2004+A1:2009, ANSI/ASME B30.21, AS1418.2 and SANS 1636.
