Long Lasting Trailer Flooring
A unique lamination process differentiates Prolam's hardwood floor, according to manufacturer. Conventional trailer wooden floors are laminated from oak or maple, with each stick in the laminate keyed to the next in the laminating/gluing process with a simple hook joint. Prolam uses a unique Zig-Zag profiling of the ends of each stick in the flooring laminate strips
The carefully machined Zig-Zag has the ability to distribute vertical loads at both sides of the joint, evening the stress distribution of point loads such as the wheels of a fork-lift truck.
This, plus careful preparation of the maple or oak used in its floors and the use of Melamine Ureate adhesive combine to make a flooring material that is 5 to 18% stronger in direct dry and wet shear tests. It is up to 40% more durable over the life of a trailer, says Prolam.
The flooring construction also provides exceptional strength to the flooring and a highly efficient barrier to water ingress. The Zig-Zag joint swells with any water present and acts as an extra efficient barrier to the seepage of water through the joint area.
Another differentiating factor is the hand lay-up during the floor laminating process. Trained and experienced employees assemble a continuous jigsaw puzzle of advancing trailer floorboards in the gluing process. This ensures an even distribution of the joints of the randomly sized sticks, to keep all joints evenly spread over the boards in a floor for the maximum strength.
Testing shows the Prolam maple floors exceed industry shear test standards by a factor of three.
Powered Landing Gear
The Holland Group has released the PowerLeg 20K Series, an integrated, electric-powered landing gear system developed in partnership with Quest Transportation Products. The PowerLeg is driven directly through the landing gear's transmission and provides the torque necessary for quick operation. A push of the button raises or lowers up to 20,000 lbs. more quickly than manual cranking. An in-cab control option is also available.
The system also helps stabilize and adjust to varying dock heights. The floating riser nut reduces dock walk and ensures easy travel.
According to Holland, the system installs easily and offers low maintenance and reliable performance. All system components (control box, wiring harness, attachments, landing gear and back-up manual crank) are supplied, and a variety of optional mounting styles are available.
