LB-SC Heavy Duty Lever Hoist with Overload Protection

Protect your people and your investment.

With all the benefits of the standard Kito LB and also equipped with an integrated slip clutch, the LB-SC is guaranteed to help prevent injuries or damages on the job site. The slip clutch engagement is smooth and seamless with no erratic motion to make sure the load remains steady while lifting. Your people are safer and your hoist lasts longer with less down time for maintenance. That’s why the LB-SC is increasingly becoming the trusted choice for heavy industry.

Unique Slip Clutch

Protecting the hoist and operator are essential. The unique slip clutch on the LB will engage when an excessive overload is detected keeping the load stationary and secure regardless of any additional hand force applied.

Failsafe Freewheel System

Our widely acclaimed fail-safe freewheel system closes the gap between operator safety and load control. Developed in-house 30 years ago, the freewheel mechanism was intentionally created as a two-step process to eliminate the risk of accidental free chaining. The result is dramatically improved functionality and operator safety.

Safety Tip Hook and Latch

Taking a hoist off-duty because of a damaged or broken hook latch is unacceptable. That’s why the LB-SC latch was specifically designed to protect it from damage. The notch on the end of the latch is engineered to engage the tip of the hook to protect against lateral impact damage. The latch is also constructed of heavy gauge steel and secured by a widened anchor at the base to increase its rigidity.

State-Of-The-Art Chain Technology

Kito has successfully established a world-renowned reputation for manufacturing a lighter-weight, ultra-strong, high-performance load chain. What’s more, the LB Grade 100 chain uses a shorter and narrower link profile for greater surface area contact, which improves wear resistance and overall tensile strength.

Structural Steel Side Plates

Regionalized heat-treated side plates provide extreme rigidity to maintain proper body shape and operational efficiency, no matter what the load is. This heat treatment process also prevents abrasion to the load chain during contact with the side plates. This functionality is another example of how Kito is committed to keeping the LB-SC working longer.

L5LB Freewheel Function

LB Series

The L5LB forged an entirely new, industry-leading benchmark by being smaller, lighter, and stronger than any other lever hoist on the market. Its proven strength and durability stand up in an endless array of grueling applications, including environments where temperatures drop to a bone-chilling -40 ˚C.
