New from Waltco Truck Equipment is the Direct Lift Extra Tough rail-type liftgate, the WDL-XT, It’s available in
three weight capacities — 4500, 5500 and 6600 lb — and in both steel and aluminum platforms. It’s the next
generation of the WDL series, with a number of new design features aimed at enhanced performance and reliability,
ease of use and reduced maintenance.
Closed-circuit, volume-balanced lift cylinders are said to ensure an even lift under any loading condition, without
the use of a flow-divider valve. The self-bleeding lift cylinders, which are matched to gate capacity, also help
reduce installation time, Waltco says. All wiring and connections feature a ‘plug & play’ design and meet or exceed all Technology & Maintenance Council (TMC) recommended practices. The hydraulic system, with a thermally protected power unit, is designed to maximize the fluid flow rate, enhancing the liftgate’s operational performance while minimizing amperage draw requirements.
Other standard features include hardened steel rollers mounted on tapered roller bearings to minimize friction and
drag; sealed roller bearings to reduce contamination; a gravity and spring-actuated Positive Transit Mechanism
(PTM), which is automatically released when the gate is lowered; and pneumatically assisted deck opening. LED
lights are fully recessed to reduce both damage and theft potential, and the operating switches are fully weather-
sealed and protected. The wiring harness is designed to stay completely stationary while the liftgate is in
