Above Floor Travel
On specific rail-type models, this option allows your cargo to travel above the floor level of the truck or trailer based upon the bed height of your application.
Bed Height
The vertical distance from ground level to the floor surface of the vehicle.
Bed Height Range
When specifying a liftgate, the lesser dimension refers to the bed height when the vehicle is loaded to maximum weight capacity. The greater dimension refers to the bed height when the vehicle is empty.
Below-Bed-Height Storage
Option found on many railgate models that allow the liftgate platform to be stored so its highest point is below the bed height of the vehicle, thus allowing unobstructed access to the rear of the vehicle without having to operate the liftgate.
Cart Stops
A device used to prevent wheeled cargo from rolling off the ramp end of the liftgate platform.
Conventional Liftgate
A liftgate that is welded or bolted to the frame of the vehicle chassis. In the stored or travel position, the lifting platform is in the vertical position at the rear of the vehicle.
Dock Bumpers
Optional protective steel structures used commonly with Flipaway models that are welded below bed level at the rear of the vehicle to protect the liftgate from damage caused by loading dock impact. May have the capacity to also house the vehicle tail lights.
Flipaway Liftgate
A liftgate that is welded to the frame of the vehicle chassis. The loading platform is designed with two or three folding sections. In the stored or travel position, the platform is folded and stored beneath the body floor allowing access to the cargo area without activating the lift.
Cantilever Lift
A Cantilever liftgate is a self-adjusting platform that stays level relative to the truck bed throughout the entire raise and lower cycle. Options are also available to convert the platform to a dock board or for use as a rear door.
Gravity Open, Power Close
Hydraulic close, torsion spring/gravity open.
Galvanization
The process of applying a protective zinc coating to steel or iron, in order to prevent rusting.
Load Capacity
Maximum amount of cargo weight that a given liftgate is rated to handle during one cycle. Full rated capacity is based on the cargo being centered on the platform as close to the vehicle as possible or the weight being evenly distributed over the entire platform surface.
Mount Frame Clearance
Distance required between the rear-most obstruction on the chassis and the end of the vehicle body in order to mount a liftgate.
Power Open, Power Close
Hydraulic operation of the liftgate platform during the open and closing portion of the cycle, which allows for consistent opening and closing speed regardless of the climate conditions.
Power Up, Gravity Down
Hydraulic operation raises the liftgate platform, while its own weight lowers it.
Power Up, Power Down
Hydraulic operation of the liftgate platform during the raise and lower portion of the cycle, which allows for consistent lifting and lowering speed, regardless of the climate conditions.
Rail-Type Liftgate
Medium / Heavy / Bottle Gas / Pick-Up / Service Body / Dump Thru
Railgates have vertical tracks that weld or bolt to the rear frame of a truck body or trailer. The loading platform travels up and down on these tracks through the use of cables or chains in conjunction with a hydraulic cylinder, or the use of two hydraulic cylinders directly attached to the loading platform. In the travel position, the platform stores over the rear door, although an option is available to allow storage below the door.
• Medium Rail-Type Liftgate – References the lift capacity. • Heavy Rail-Type Liftgate – References the lift capacity. • Bottle Gas (BG) Rail-Type Liftgate – Offers design features targeted to the bottle gas delivery industry.
Reduced Maintenance
Standard on all Waltco liftgate models, independently or a combination of fiberglass-reinforced Teflon™ bearings, slide pads and grease zerks to allow additional protection to the major pivot points on your liftgate.
Retention Rail
Railing around the platform perimeter that supports and restrains bottled gas cylinders during delivery. Used on MDLBG, PTBG, RBGL and WDVBG Bottled Gas models.
Sideloader Liftgate
A liftgate that is typically mounted below the side door of a truck body or trailer and can be either frame or body mounted, depending on the application. In the stored or travel position, the platform stores under the body and is either unfolded or extended out from under the door.
Snubber Kit
A structure consisting of a steel brace and a rubber bumper pad used commonly with Flipaway models. The snubber kit stabilizes the liftgate platform while in the transit position, minimizing potential for damage due to bouncing and/or road vibration.
Torsion Bar Assist
Reduces platform opening and closing forces with the use of spring loaded counterbalanced torsion bars or rods.
