TANDEMLOC has released the Modular Autoloc spreader frame for lifting containers. Using four twistlock bayonets, the spreaders are simultaneously actuated by slackening the four-legged sling from a fully tensioned position. The bayonets twist approximately 90 degrees each time the four-legged sling assembly is fully slackened and alternates between lock and unlock. Operation is mechanical, with no electronics or hydraulics. No ground personnel is required to lock/unlock the twistlocks.
The small diameter cable links the Autoloc arm located near the center of the spreader to the master link. This cable does not carry any of the lift load. The Autoloc system linkage operates the bayonets each time the sling is slackened.
The frame can be disassembled from its lifting footprint down to a pallet-ready square that can be shipped inside the container it has lifted. The design is scaleable and can quickly transform from a 20-foot unit to a 40-foot unit with a simple pin-together conversion kit.
Wire rope rigging has a “Flemish Eye” style termination point, which is reliable and recommended by FEMA over any other style termination point. Built-in “Indicator Flags” allow the crane operator to easily locate the spreader onto the waiting container. Tandemloc’s ratchet-style gearbox provides the user with operational confidence, as it has been field proven since 1993.
The lifter can be customized for the application, and it has been proof-tested to 125% of the working load limit.
