Plastic cribbing blocks from Enerpac (A Division of Actuant Corp) have been introduced as a safety initiative by CablePrice NZ Ltd for use with machinery widely used in the construction, forestry, transport, agriculture, quarry, mining and demolition industries.
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.
Developed as a more stable, longer-lasting and easily cleaned alternative to wooden blocks, the plastic cribbing blocks optimise safety when stabilising heavy loads after they have been lifted for maintenance and access. The plastic cribbing system was supplied to CablePrice by Enerpac distributor Jonel Hydraulics
Available throughout Australia and New Zealand, Enerpac’s plastic cribbing blocks 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.
According to CablePrice Rotorua Equipment Workshop Team leader, Chase Murphy, the blocks are able to support equipment weighing up to 30 tons. They were using wooden blocks previously, which ran the risk of cracking under load, compromising the safety factor. Enerpac’s plastic cribbing blocks provided an effective safety solution when lifting up machinery for service inspection and maintenance.
Following an on-site demonstration of the plastic cribbing blocks by Enerpac NZ Territory Manager Mr Neville Stuart, CablePrice placed an order for 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.
Impressed with the block’s safety, performance and versatility, CablePrice ordered more for themselves and another 100 for other branches.
Mr Stuart explains that the plastic cribbing systems will not splinter or 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 in nylon carrying totes.
The plastic 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 for industrial markets, where its technologies are used to safely hoist loads as large as turbines, ships, railway locomotives, bridges, mining shovels and entire buildings.
