About the Tiger SS11 Subsea Lever Hoist

Tested and verified above international standards the SS11 subsea lever hoist can be used in salt water multiple immersion operations, providing the usage procedures are strictly adhered to, these are found in the immersion manual supplied with the hoist. Testing has been completed beyond the ASTM B117 environment condition requirements with over 1300 hours of continuous exposure to a generated test programme in subsea environments.  The SS11 meets and exceeds all necessary requirements. For this reason you can be sure of a quality lever hoist which is capable of multiple lifting tasks whilst immersed in sea water.

Key Features of the SS11 Subsea Ratchet Lever Hoist

There are 7 models in the range of subsea lever hoists with safe working lifting capacities ranging from 0.8 to 20 tonne.  The patented quad cam pawl brake provides optimum safety by ensuring there is always one pawl engaged. If a pawl spring fails, the load will still be held securely and the brake will still be operational. The brake operates with a unique inertia driven torsion switch brake; together with the auto-engaging free-wheeling device which engages at the slightest resistance you can be assured of maximum safety. The marine friction discs are bonded and free of asbestos, perfect for subsea use. An eight part multi-start thread pinion shaft is used to further increase the brake reaction times; rotational brake engagement works together with the load sheave direction, therefore giving high brake ratios of up to 50% when compared to a hoist with a 4 point pinion thread.

The special brake system on the SS11 offers light load failure protection with a 2 step process which puts the hoist into neutral when under load at 2% of the rated capacity. This gives high efficiency whilst ensuring high safety levels and easiness of use for the user.

These lever hoists come with safety latched top and bottom hooks although these can be changed out for a range of other connectors (see image). The hooks use the ‘EZ’ check system for easy checking for previous overloading.
