Patented Hardening Process

An advanced high-frequency heat treating process ensures uniform hardness on all key load bearing parts. The process creates a truly rugged hoist you can confidently take into any environment.

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 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

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 working longer.
