Tiger SS20 Subsea Chain Block Features

With easy portability thanks to being relatively light and compact the SS20 chain block can be used across many locations easily enough, and can also be used in fleeting or cross hauling tasks for which it has been tested and subsequently certified.

The load and hand chains have corrosion protection and the brake chamber has a double cover. The brake system uses bonded, grooved marine friction discs which have a reliable braking surface area in wet conditions. The grooves help to disperse water away from the surface.

The SS20 Chain block boasts an 8 point thread pinion shaft for multi-start, doubling the lead distance and thus increasing brake efficiency; by 100% when compared to a typical 4 point system.

The quad cam pawl system with 2 reciprocating cam pawls ensures optimum brake safety.

Bearings are from phosphor bronze for optimum corrosion resistance.

On the bottom hooks the yoke forgings are recessed and provide full protection to the anchoring bolts preventing any debris from entering and subsequently restricting the load sheave.

Special chain bags are available to suit your chain length and incorporate drainage holes and a stainless frame.
