One of the products we manufacture is Twin-Path® high performance slings which have revolutionized lifting industries allowing users to handle heavy loads without the inconvenience of very heavy wire rope slings. These super strong and yet very lightweight products are 1/10th the weight of steel but up to ten times stronger. 

Testing Facilities

Our testing facilities are capable of testing wire rope slings, Twin-Path® slings, and braided wire rope slings to capacities over 600 tons. Fall protection is a very important aspect of our rigging business as we supply harnesses, lanyards, lifelines and all types of tie-off hardware and shock absorbers for all applications.

In 2009, The Carpenter Group completed the installation of a 1,200,000 pound, 120 ft. horizontal test machine. Built by Chant Engineering, it features elongation measurement while having cycle and break testing capabilities from a low of 150,000 lbs. force to a high range of 1.2 million lbs. force. The machine is calibrated to ASME-E4 standards and includes updated software which prints a certificate with a graph tracing the actual low value to the high value of the load test.

We will pull test any assembly or fixture up to 600 tons. We provide certification with traceable calibration to Spec E4 National Standards. And Reliable Delivery... on the job, on time, anywhere — from California's largest inventory of supplies to lift, pull, push, or place anything.
