CablePrice introduce Enerpac plastic cribbing system to optimise load safety


A safety initiative by CablePrice NZ Ltd has seen it introduce a new system of plastic cribbing blocks designed to optimise safety when stabilising heavy loads after they have been lifted for maintenance and access.

The Enerpac plastic cribbing system – developed as a more stable, longer-lasting and easily cleaned alternative to wooden blocks – was provided by Enerpac distributor Jonel Hydraulics for use with machinery widely used in the construction, forestry, transport, agriculture, quarry, mining and demolition industries.

The blocks, available throughout Australia and New Zealand, feature an aggressively patterned slip-resistant pyramid locking surface for superior stability in cribbing, chocking and shoring. Unlike wood, plastic offers a stable, predictable and high load capacity which ultimately deforms only slowly under extreme load, because of the homogeneous material used.

“We have had up to 30 tons sitting on them – we use them for everything. It is all about safety,” said CablePrice Rotorua Equipment Workshop Team leader, Chase Murphy. CablePrice, a subsidiary of Hitachi Construction Machinery Co, is the country’s only authorised dealer for Hitachi construction machinery, Scania trucks and buses, and John Deere construction and forestry equipment.

“Previously we used wooden blocks, but this is the way of the future for an industry leader. Sometimes we could hear wooden blocks cracking under load. We are always obsessed with safety, so we sought a better way to ensure it when lifting up machinery for service inspection and maintenance,” said Chase.

Enerpac NZ Territory Manager Mr Neville Stuart said that after he went on-site to demonstrate the blocks, CablePrice ordered 24 x LPC6701-B, 6 x 7 inch blocks from Jonel Hydraulics’ range of Enerpac cribbing systems, which can support up to 60 tons in two-box cribs and 100 tons in three-box cribs.

“They were very impressed with the block’s safety, performance and versatility and ordered more for themselves and another 100 for other branches. This product, like other Enerpac globally proven technology, is extensively proven and backed in the field by companies such as Jonels with strong expertise in lifting and safety.”

The cribbing systems complement Enerpac’s broader ranges of powerful but compact lifting and load handling technologies including heavy duty load skates, low clearance machine lifts and vertical lifting wedges requiring only 10mm tip clearance to apply 700 bar hydraulic force.

Enerpac is the recognised global leader in high-force tools and 700 bar hydraulic equipment used in industrial markets, where its technologies are used to safely hoist loads as large as turbines, ships, railway locomotives, bridges, mining shovels and entire buildings.

“Our total ranges are keyed to safety and cost-efficiency, which is the case with plastic cribbing systems being used when maximum crib stability and material durability is required by industry leaders such as CablePrice NZ Ltd,” says Mr Stuart.


“Enerpac’s cribbing system won’t splinter, doesn’t absorb most fluids (subject to chemical compatibility tests) and can be used for interlocking box cribs, parallel cribs and triangle cribs.”

Available in three sizes of cribbing blocks and two sizes of wedges, the system, made from recycled plastic, is available in different combinations of wedges and blocks.
