N3100 Autoloc® Container Spreader Frame

Self-actuating container lift spreader whose four twist-lock bayonets lock and unlock automatically when the sling is slackened.

Description

The Autoloc® fixed container spreader lifts ISO containers using four twist-lock bayonets that are actuated simultaneously by slackening the 4-leg (or two 2-leg/double hook) sling from a fully tensioned position. Each time, the bayonets twist approximately 90 degrees, alternating between lock and unlock. Operation is purely mechanical, with no electronics or hydraulics, and no ground personnel are needed to lock or unlock. Tandemloc designs and manufactures its equipment at its Havelock, North Carolina facility, where products are proof tested in-house.
