LIFTGATE GLOSSARY




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.
