A Comprehensive Guide to the Harrington LB Heavy Duty Lever Hoist
The Harrington LB Heavy Duty Lever Hoist stands as a pinnacle in lifting equipment, combining rugged, all-steel construction with a surprisingly lightweight design that outshines comparable aluminum models. This hoist is meticulously engineered to meet the demands of heavy-duty lifting operations, offering capacities ranging from 3/4 Ton to 10 Ton and lift options from 5' to 20'. What sets the Harrington LB Lever Hoist apart is not just its raw power – but the unique features that make it a standout performer in its class.
What Are the Unique Features of the Harrington LB Heavy Duty Lever Hoist?
1. 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.
2. 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 wide anchor at the base to increase its rigidity.
3. Structural Steel Side Plates: Regionalized heat-treated side plates provide extreme rigidity to maintain 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 side plates.
4. Certification and Corrosion Resistance: A test certificate verifies that every hoist has undergone factory load testing to 125% of the rated capacity, meeting ASME B30.21 requirements. The Grade 100 heat-treated load chain is nickel-plated for corrosion resistance, ensuring durability even in challenging environments.
What Are the Design Features of the Harrington LB Heavy Duty Lever Hoist?
1. Positive Braking Action: The Weston-style load brake incorporates two moisture-resistant brake pads with four braking surfaces, ensuring reliable and precise braking. The inclusion of two brake pawls enhances reliability, making it a trusted choice in demanding environments.
2. Enclosed Brake Mechanism: The hoist boasts a totally enclosed brake mechanism, providing protection against dirt and moisture. This feature contributes to the hoist's longevity and performance, even in challenging conditions.
3. Durable Gearing: Machined, heat-treated, split load double reduction gears ensure a long life for the Harrington LB Lever Hoist. These gears are designed to withstand heavy loads and tough operational conditions.
4. Compact Design: Operating in close quarters is made easy with a short steel handle and 15-degree recovery strokes. This design feature enhances maneuverability in confined spaces, providing versatility in various lifting applications.
5. Spring-Loaded Freewheel Mechanism: The patented spring-loaded freewheel mechanism allows for easy adjustment of the load chain while safeguarding against accidental freewheeling under load. This innovative feature adds an extra layer of safety to the hoisting process.
6. Non-Slip Operation: Equipped with a standard rubber grip, the Harrington LB Lever Hoist ensures a non-slip operation, promoting user safety and control during lifting operations.
7. Forged Alloy Steel Hooks: The forged and heat-treated alloy steel hooks open slowly without fracturing under excessive loads. Both top and bottom hooks rotate 360 degrees, providing flexibility and ease of use.
