Tiger PROCB14 Chain Block

The PROCB is manufactured from the highest quality steel materials precisely machined in our own factory, offering a lightweight, compact and rugged construction, producing an exceptionally strong product resistant to impact damage.

The especially low headroom allows for easy installation in the most restricted environments. The unique design features - including our patented Quad Cam Pawl System - give it significant safety advantages over standard chain blocks and make the PROCB chain block the ideal tool for long term use with low maintenance and servicing costs.

These units meet and exceed all the requirements within BS EN 13157: 2004+A1:2009, ANSI/ASME B30.16, AS 1418.2 and SANS 1594.

The PROCB with overload protection is DNV GL Verification tested according to NORSOK R-002.

Tiger patented Quad Cam Pawl System guarantees permanent engagement of at least one of the two reciprocating cam pawls fitted to the PROCB, ensuring the pawl only just clears the ratchet wheel, with the minimum of clearance as required under BS 4898:1973. But most importantly, in the unlikely event of a pawl spring failure, this design will ensure the brake is still fully functional and the load is sustained without damage to the mechanism.

Key design features such as our patented brake pawls and deep pocket design hand wheel along with the full and comprehensive testing regime we have submitted our PROCB hoist to provide the evidence that allows us to state that these units can be safely used for “fleeting”, “drifting” and “cross-hauling” applications up to 45° from the vertical without deration.

Tiger uses an 8 point multi start thread pinion shaft which has also increased brake reaction times.
