A lift truck having horizontal arms straddling the kettle it is to lift, carry, and tilt. On the outer end of each arm is a tilting unit, one being a drive unit, and on the other an idler unit. These units grip the handles of the kettle. They are symmetrical, but otherwise identical. Each includes a swinging pendant latch, which yields on engaging the kettle handle, and then swings back into latching position. The units in the arms have interengaging elements preventing sliding of the kettle when it is in tilted position. Two sets of proximity switches are included for shutting off the tilting driving motor when the movable parts of the gripping units are not in safe position.
