Time is money. The Gripper™ Truss Hook offers a revolutionary way to handle wood roofing trusses quickly and easily. Its patent pending design reduces labor costs, improves worker safety and helps to ensure regulatory compliance. The Gripper™ speeds up the construction process because more trusses can be set in less time. Timesavings over conventional methods of 50% or more, on average, are possible, which allows for more aggressive bidding.
Traditionally, roofing trusses are hoisted into place by cranes using slings or rigging that, according to Occupational Safety & Health Administration (OSHA) regulations, must be securely attached to the truss. Attaching and detaching the rigging takes precious time. Once the Gripper™ has been positioned on the truss, a worker pulls the trigger mechanism, causing a spring-actuated cam with serrated teeth to bite into the truss, securely holding the hook in position. After the truss is set, the worker pulls the unlocking cable, releasing the Gripper™ from the truss. While the framing crew anchors the truss, the crane operator can move to the next one.
