Twin Chain Servo Hoist
Twin Chain Servo Hoist / Dual Motor
Models: KSHTC250S-2401 | KSHTC500S-2401 | KSHTCDM700S–4000S-4803
The Knight KSHTC Twin Chain and KSHTCDM Dual Motor hoists are Intelligent Assist Devices (IAD) that let the operator position or balance a load precisely along the “Z” axis (vertical) with high speed and reliability. The design suits awkward or long parts that need to be kept under control.
Both ranges include the “SDS” (Safety Drop Stop) feature. On the KSHTC, the two chains are mechanically linked and run as a single unit. On the KSHTCDM, each motor is electronically synchronised, with the option of an LMM module with OCI or LMM with pass-through.
Knight’s servo technology lets the operator simply grip the handle and move the load, with no buttons to press, improving accuracy, responsiveness, repeatability, safety and throughput. The inherent benefits include eliminating wasted motion, shortening reaction time, and reducing inertia effects with heavy loads.
