WLL: 70,528 LBS

Proof Tested: 125% of the WLL AFTER EVERY RENTAL

Calculated Weight: 2,800 LBS

Standards: Meets ANSI B30.20-2013 and ISO 3874 Specifications. 

Operation: The Tandemloc Autoloc® operates strictly through mechanical connections-no hydraulics or electronics are required. Twistlocks will lock and unlock when the sling assembly is slackened, making the Tandemloc Autoloc® more convenient than manual spreaders. 4 Leg wire rope slings are included with each spreader for operation. 

Tandemloc Autoloc® Container Spreaders are equipped with 4 twistlock bayonets that are simultaneously actuated by the slackening of the 4 legged sling from a fully tensioned position. The bayonets twist approximately 90° each time the 4 legged sling assembly is fully slackened, which causes the twistlock bayonets to alternate between the locked and unlocked positions. 

A small diameter cable, called the activator sling, links the Tandemloc Autoloc® container spreader's gearbox arm near the center of the spreader frame to the 4 legged sling assembly's master link. NOTE: This activator sling does NOT carry any of the lift load. The Tandemloc Autoloc® system linkage operates the bayonets each time the sling is slackened.
