KIWI ingenuity has helped resolve a safety issue faced by industry on both sides of the Tasman - how to ensure the ongoing safety of chains used in a huge variety of lifting, pulling, securing and heavyweight materials handling tasks.

Hydraulic engineering specialist Kasco has delivered to Steel and Tube Distribution New Zealand three mobile chain test rigs installed in vans which visit companies to help them comply with new occupational safety and health (OSH) requirements.

The rigs - powered by an Enerpac RCH 306 hollow cylinder especially constructed for testing, maintenance and tensioning applications - apply forces significantly exceeding the load expected on the chains, to ensure they won't break and are continuing to perform with a wide safety margin.

Kasco uses the RCH 306 cylinder to provide up to 155mm of stroke, with the hollow plunger design allowing a threaded rod to pass through the cylinder for fast adjustment of chains and strops.

The single-acting, spring return cylinder (which can apply both push and pull forces) is powered by an Enerpac P 392 handpump, with two-speed operation and lightweight, carbon fibre body construction.

Forces generated by the high-pressure (700 Bar, 10,000psi) hydraulic equipment are precisely checked with a digital gauge. Applied Power Australia 02 9743 8988.
