New Automatic Hydraulic-Operated Lumber Truck UnloadingDevice

An entirely new, fully automatic, hydraulic-operated lumber truck unloading device which allows lumber to be unloaded quickly, with precision and complete control has recently been announced by Paul Penberthy, president, Penberthy Lumber Company, Los Angeles, California.

The use of the unloader arm allows lumber loads to be deposited exactly where they are wanted (even on carrier blocks) without the customary thunderous crash and needless, costly breakage.

In successful operation at the present time, the new unloader arm, which may be installed easily on any lumber truck, is an extra roller supporting the tail end of the load and is part of a cranked arm pivoted under the rear end of the chassis. ft is maintained in position by a hydraulic cylinder attached to a bel crank on the unloader hinge tubes. To unload, the lumber is rolled back to a point of balance between the last fixed roller and the unloader arm. A hydraulic control valve is then opened from a remote control unit on the rear of the left body panel, or from a unit on the steering column in the cab. This action allorvs fluid to escape from the cylinder, permitting the cranked unloader arm to descend in an arc, tilting the snubbed load until it rolls gently, rear end to the ground.

The truck is then moved forward until the front end of the load rests solidly on the unloader arm, which is then allowed to continue its descent to the ground. Power for the unloader arm return is supplied by an aircraft seven cylinder hydraulic pump operated by a six volt electric motor. Switch buttons are located at both remote control stations. Micro-switch over-travel interrupters are used to protect the electric and hydraulic circuits.

The truck itself is unique in the lumber field. Designed by Wellington Everett Miller and built by Bohman & Son, Pasadena, the new truck has metal oak-lined body sides three-quarter cab high the complete length of the truck.

J. W. (Jim) Steele, formerly with Pope & Talbot, Inc., Lumber Division, and Twin Harbors Lumber Co., has joined Atkinson-Stutz Co., and will cover Washington and a portion of Oregon, calling on the mills. W. J. (Bill) Ryan, of the Grants Pass office of Atkinson-Stutz Co., is norv calling on the mills in Southern Oregon.

'Ihese sides swing open from the center to allorv conventional loading methods. Complete fenders front and rear, roller pillar blocks and floor pans are a close knit unit that protects loads from dirt, grease and rvater. A further innovation is an extension tail light mounted on an Appleton "Reel-lite" 25-lool cord with a "C" clamp for attaching to load for after-dark operations.

Harry W. Aldrich, of H. W. Aldrich Lumber Co., Ettgene, Oregon, was a recent San Francisco and Fresno visitor on his way to Arizona, Texas and Louisiana. He will also call on a number of hardrvood mills in the south. He is accompanied by his wife and daughter on the trip, which is being made by automobile.
