Top quality, heavy duty, compact and lightweight lever hoist, equipped with the twin brake mechanism of the Tiger SS11 for added safety. Available with Optional Top and Bottom 'Adaptor' Fittings.

Lightweight, compact and rugged construction with the handle, gear case and brake cover made entirely of pressed steel, producing strong resistance to impact damage.

Using only the highest quality materials precisely machined throughout ensures the PROLH is the ideal hoist for long term use with less maintenance and servicing costs.

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

A subsea version of the ProLH is also available, see the Tiger SS11 lever hoist for further information.

Tiger Prolh Lever Hoist
Dual Brake Mechanism

Quad Cam Type Brake Pawls

This latest development in brake efficiency guarantees permanent engagement of at least on of the two reciprocating pawls fitted to the PROLH, ensuring the pawl only just clears the ratchet wheel, with the minimum of clearance as required under BS 4898:1973. Most importantly, in the unlikely event of a pawl spring failure, this new design will ensure the brake is still fully functional and the load is sustained without damage to the mechanism.

One Piece Construction Pinion Gears

PROLH gear boxes contain one piece pinion gears. This revolutionary process in gear manufacturing uses drop-forged raw material, precision machined and heat treated with precise ratios between teeth and body.

Light Load Protection

The unique brake system designed for the PROLH guarantees a light load protection at 2% of the rated capacity.

Overload Protection

The PROLH lever hoist can be fitted with a slipping clutch overload mechanism to protect it from overload. When the load limit is exceeded, the clutch in the chain wheel will slip, allowing the handle to be operated whilst not engaging the gear box. The prevents further lifting of the load, though lowering is still possible.

Chain Stripper

The new chain stripper is specifically designed to guide the load chain safely onto or off the load sheave without snagging or jamming. The fluted chain stripper allows the safe use of the PROLH when used in any orientation.

Brake Efficiency

Tiger uniquely uses an 8 point multistart thread pinion shaft which has measurably increased the efficiency in brake reaction times.

Load Chains

Tiger only use the highest quality alloy, calibrated load chains in Grade 80 (T) or 100 (V) conforming to EN818-7 and ISO 16872. The PROLH comes as a 1.5m standard Height Of Lift (HOL), but can be chained up to whatever length required. Stainless steel load chain is available on request.


The Tiger Lever Hoist handles are ultra strong, with strengthening side ribs which protects again impact damage, protects the ID badge / label, increases robustness and longevity, and eliminates torsion.


The hooks incorporate "EZ Check" (Patent Pending GB1420387.1) feature which allows operators and inspection engineers to easily check to see if the hoist has been previously overloaded or shock loaded, by simply measuring between the triangle of pop marks.

The alloy hooks are drop forged and heat treated and are furnished with heavy duty latch kits that fully engage into the nose of the hook offering maximum load security. The swivel hooks are attached to the yoke using high grade nuts & socket head bolts allowing for complete inspection during any statutory inspection or written scheme maintenance. Also available with spark resistant hooks.

Mechanical Efficiency

All major components are heat treated and precisely machined to ensure long term smooth operation. High gear ratios keep physical effort to a minimum.

Safety Brake

The PROLH comes equipped with a unique dual brake mechanism that automatically engages when the lever hoist feels the slightest resistance on the bottom hook. This key feature means that the PROLH will raise, hold, and lower the lightest of loads without slipping. The two stage process protects against accidental light load failures caused by putting the hoist into neutral whilst under load.

The bonded friction discs are free of asbestos and achieve highly efficient braking.


Chain end stops

User friendly heavy duty end stops make it easy for the operator to position the chain while "freewheeling”, but most importantly the standard "end stop" will hold a load of at least 2.5 times the rated capacity when supporting the full load without restraint from other components e.g. brake or gearing.

The PROLH lever hoist has undergone a full test program that includes:

Type Testing

  • Ultimate strength test, at least 4 times the Working load limit (WLL)
  • Chain end anchorage test, passing at least 4 times the WLL without any restriction of the brake or gears.

Test on every hoist

  • Proof loading at 1.5 times the rated capacity
  • Light load testing at maximum of 2% rated capacity


High performance premium quality grease allows the PROLH hoists to be certified for use within a temperature range of -40°C to +50°C far exceeding the requirements of current standards.


The PROLH is finished in our high quality powder coat paint offering excellent corrosion protection.
