JET L-100 series manual chain hoists combine a true rugged industrial design with highly refined quality culminating in the last manual hoist you may ever need to purchase. The attention to detail in the design of this series is second to none. The drop forged, carbon steel hooks are quenched and tempered to increase strength and will slowly stretch to indicate an overload situation. Cast steel safety latches, attached with Allen head screws and lock nuts, outclass the industry standard of stamped safety latches. The induction hardened, 100 grade load chain provides 20% more strength then the common 80 grade load chain found on inferior hoists. The double enclosed brake cover keeps dirt and debris away from the brake mechanism. While the sealed ball bearing supported load sheave provides efficient and smooth operation. The investment cast anchor plate, and all other internal parts are fully heat treated and quenched for added strength and reliability. Finally, all the internal parts are Zinc coated for additional corrosion protection. The triple spur gear drive train features alloy steel gears that have been heated treated, quenched and then case hardened for a life time of service. Finally, the patented fused brake disc design means little to no maintenance is required to keep these hoists operational. All L-100 series hoists are factory tested and certified. Each hoist comes with a completed test certificate from the factory. Don't settle for anything less.
