Waltco Truck Equipment Co. designed its Waltco Direct Lift (WDL) Extra Tough (XT) rail-type liftgate for the most demanding applications. The Waltco WDL-XT is available in four weight capacities: 3500, 4500, 5500 and 6500 pounds, and in both steel and aluminum platforms. Waltco says the WDL-XT has a number of new design features for enhanced performance and reliability, ease of use and reduced maintenance.
According to the company, closed-circuit, volume-balanced lift cylinders ensure an even lift under any loading condition, without the use of a flow divider valve; and the self-bleeding lift cylinders, which are matched to gate capacity, also help reduce installation time. All wiring and connections feature a plug-and-play design, Waltco says. The hydraulic system, which incorporates 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, according to the company, include hardened steel rollers mounted on tapered roller bearings that minimize friction and drag and improve overall performance of the lift; sealed roller bearings to reduce contamination and extend bearing life; a gravity and spring-actuated Positive Transit Mechanism (PTM), which is automatically released when the gate is lowered; and pneumatically assisted deck opening.
Lower columns are reinforced with a one-inch steel wrap to help reduce the potential of damage caused by backing into loading docks, while LED lights are fully recessed to help reduce the potential for both damage and theft. Hinged covers on the columns are designed to make it easier to access key components for service and maintenance. To minimize wear and tear, the operating switches are fully weather-sealed and protected, while the wiring harness is designed to stay completely stationary while the liftgate is in operation.
