Landoll Trailers Feature New Hydraulic Operating System
Landoll has introduced a new hydraulic operating system, nicknamed H.O.S.S., and High Visibility Lighting package. Its 400 “A” Series Traveling Axle trailers are the first models showcasing these standard features.
H.O.S.S. cuts the overall operational time in half, the company reports. The speed of the axle traveling forward has increased by 36 percent, moving back by 58 percent. Tilt deck positioning has increased nearly 63 percent, while winch in and out speeds are closer to 66 percent improvement, helping increase operator efficiency and allow for more loads to take place.
“The speed is the most noticeable change, but the long term value is the damage and downtime prevention,” said Gary Dwerlkotte, Landoll Trailer Sales Coordinator.
Removal of restrictors eliminate considerable back pressure, resulting in cooler operating temperatures and a quieter environment. Continuous oil encasement of valves in the control panel require less maintenance. Previously, oil circulated through the entire system before returning to the tank, allowing for only a 14 GPM flow. Oil now only travels through the closed center inlet and back to the tank, creating a 20 GPM flow.
Brad Bergman, Landoll Engineering Project Manager, stated “there was extensive field testing with three prototype valves in real life harsh environments before ever going into production.” Testing occurred in the New England Region, as well as Northern Alberta and Quebec provinces of Canada. Long term testing will continue to gather data for future development. The chosen closed-spool valve system was designed and built in Italy.
The control panel is at chest height, encouraging ergonomic and visual improvement, compared to being located on the lower arm of the gooseneck. Controls are in five predetermined hydraulic function locations, cutting out the need for modifications to the frame.
