Positech’s pneumatic LodeArm® (LA) lightweight industrial manipulator* provides excellent maneuverability of payloads up to 640 pounds, increasing workers’ capacity to perform physically stressful, repetitive lifting tasks. Easily adjustable to fit almost any work cell, the ergonomic lift assist is a high-capacity lift system in a compact package. Great for low-headroom applications, this manipulator provides rigid support and reach-in capability. This ergonomic lift assist is available in eight model configurations. It provides up to 72 inches of vertical lift and flexible mounting options.  Many safety features are available for this manipulator arm including a pneumatic safety circuit to prevent the accidental release of the part.
