Landoll Launches New "H.O.S.S." Hydraulic Operating Systems on Next Generation Trailers

The Landoll Trailer Line is leaping forward with the introduction of the Next Generation Landoll Trailer, which features new hydraulic operating systems, nicknamed H.O.S.S., and High Visibility Lighting package. The 400 “A” Series Traveling Axle trailers will be the first models with these added standard features.

H.O.S.S., the quick, quiet and quality hydraulic system offered by the Landoll Corporation, cuts the overall operational time in half. The axle travelling forward has increased by 36% and moving back by 58%. Tilt deck positioning has increased to nearly 63%, while winch in and out speeds are closer to 66%. This improvement will 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 eliminates considerable back pressure, resulting in cooler operational 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 centre 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. Jim Ladner, Landoll Corporation’s National Trailer Sales Manager, explained “the Italians are world-famous for their expertise in hydraulics. We are bringing world knowledge and technology to the Landoll trailer.”

“For several years we’ve needed to clean up the system to be more user friendly,” commented Dwerlkotte. The control panel is at chest height, encouraging ergonomic and visual improvement, versus 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.
