HU Series Ultima Hydraulic Dock Leveler

Other dock leveler manufacturers boast of individual components as though they were unrelated to each other in strength. Little thought is given to the overall structural balance of the combined load-bearing components.

Many dock leveler manufacturers fail to realize that, in many respects, the combination of structural components is similar to a chain and a chain is only as strong as its weakest link.

Through the use of state-of-the-art finite element analysis software, Pentalift components are designed and sized to maintain structural balance and harmony throughout, assuring maximum dock leveler life by eliminating any weak links.

Pentalift HU Series Ultima Hydraulic Dock Levelers are designed to provide superior product value through prolonged, trouble-free performance. Convenient push button activation and proven hydraulic technology increase the efficiency and safety of the loading/unloading process. Pentalift HU Series Ultima Hydraulic Dock Levelers provide superior performance in high frequency loading/unloading, heavy load and abusive environment applications. All Pentalift dock levelers are factory tested before shipping.

Operation
When the operator pushes and holds the raise button, the deck rises to its full height. The lip then extends into position. When the button is released, the deck and lip lower until the extended lip rests on the truck/trailer bed. If there is no truck/trailer present or the truck/trailer departs, the deck lowers, contacting the below level stops. The lip automatically drifts into the pendant position behind the dock bumpers. On units equipped with automatic return-to-stored position, the deck returns to the stored position with the lip behind the night lock. Deck lift and lip extension are controlled through the Pentalogic Hydraulic Manifold.

• Self-retracting, hydraulic lip cylinder is standard on all models for fully hydraulic operation. 
• Top-fed, forward-positioned hydraulic lift cylinder. 
• Full-range, telescopic toe protection assures total dock attendant safety. Section features a “bend relief” to maximize strength. 
• Fixed rear hinge remains flush with the rear of the pit to eliminate potential pinch points and surface obstructions. Design allows 4” of lateral deck compensation to accommodate canted truck/trailer beds. 
• Hydraulic power unit incorporating internal filtration system, 1½ Hp TENV motor. 
• Maintenance stand supports deck and lip during maintenance and service.

• High-strength safety checker plate deck and lip assembly, 55,000 psi yield. 
• Full-width, self-cleaning, heavy-wall hinge tube, 65,000 psi yield. 
• Gussets on lip and headboard hinge maximize support. 
• 50,000 psi yield headboard with bridged gaps and radii on all inside corners for maximum strength 
• Structural “I" beams. Structural "I" beams allow Pentalift to create and build the deck support with optimal strength-to-weight ratio for a dock leveler. Utilizing six (6) beams assures an even load distribution and maximum deck support. 
• Central deck beam for added support of three-wheeled vehicles.
• Full-width, structural channel tailboard and one-piece, full-width rear hinge complete with heavy steel gussets. Pentalift’s unique, welded assembly provides a box section for superior support.
• Rear frame assembly features eight points of even support for the full-width rear hinge. 
• Heavy-duty front frame provides full-width, cross-traffic support and superior building aesthetics. 
• Night lock prevents unauthorized entry when overhead door is locked on top of dock leveler.
