Bishop Lifting Products has completed the construction of a proof tester for testing slings, crane blocks, spreader bars, oilfield equipment and rigging gear.

Houston,TX-based Bishop Lifting Products recently completed construction of its new 3.3 million pound (1,500 metric ton) proof tester. With an overall length of 323 feet, and inside pulling length of around 275 feet, it's the most technically advanced proof tester ever built, the company claims. Designed and fabricated by Chant Engineering and Bishop Lifting, the proof tester is a 3-in-1 testing machine for proof testing slings, crane blocks, spreader bars, oilfield equipment and rigging gear.

David Bishop, CEO of Bishop Lifting Products, managed the testing equipment expansion project. "We've needed a larger proof tester for a long time, and moving to a new 13-acre facility made this dream an easier reality," Bishop said.
