Landoll Introduces H.O.S.S. Package

July marked the arrival of the Next Generation Landoll Trailer and the introduction of the 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. cuts the overall operational time in half. The axle traveling forward has increased by 36 percent and moving back by 58 percent. Tilt deck positioning has increased to nearly 63 percent, while winch in and out speeds are closer to 66 percent. This improvement will allow for more loads to take place, according to the manufacturer.

“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 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 (53 Lpm) flow. Oil now only travels through the closed center inlet and back to the tank, creating a 20 gpm (75.7 Lpm) flow.

Brad Bergman, Landoll Engineering project manager, said “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,” said 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.
