A lift truck clamp for handling stacked loads of different sizes has a pair of opposing clamping assemblies, one of which has a pair of clamp arms movable selectively toward and away from the other clamping assembly under the control of a pair of fluid power actuators. A linkage mechanism interconnects the pair of clamp arms so as to permit relative movement therebetween to enable the clamp arms to move asynchronously toward the other clamping assembly. The linkage mechanism includes a stop assembly preventing more than a predetermined misalignment of the pair of clamp arms, and a spring assembly imposing a yieldable biasing force biasing the pair of clamp arms toward alignment with respect to each other.
