Omaha Standard Dump Body and Hoist Reference Guide

Omaha Standard, Inc. has been an industry leader in manufacturing quality truck equipment for more than 75 years. We feature a complete line of quality-built conventional scissor, low profile scissor, and telescopic conversion hoists. Built to professionally engineered specifications, these hoists combined with an Omaha Standard body offer a total working package superior to any on the market.

This publication is designed as a basic reference manual for our hoist and dump body products. It is intended for distributors, manufacturers, truck dealers, sales people, and truck buyers. It provides general information on the selection of Omaha Standard equipment for commercial vehicles. It is not intended as a detailed engineering guidebook. Omaha Standard believes all the information and materials in this manual are accurate and reliable. Omaha Standard reserves the right to modify, change, or revise this publication and specifications and furnish equipment so altered without prior notice. For special applications or those not covered by this manual, contact an authorized Omaha Standard representative.

Our equipment is sold and serviced by a nationwide network of factory authorized Omaha Standard distributors who see to it that you receive the finest equipment on the market and that it is properly installed. Ask them for literature and additional information on the rest of the outstanding Omaha Standard equipment line.

Omaha Standard manufactures a complete and extensive line of truck bodies and truck equipment. Products other than hoists and dump bodies include:

  • Platforms (flatbeds) and associated racks and sides including steel and wood stake racks, solid steel stake sides, contractor racks, and grain sides.
  • Service bodies (utility bodies) and accessories such as HiRoofs (canopies), low sliding roofs, bumpers, trays, and ladder racks.
  • Toolboxes including above body and under body models.
  • The Eagle Lift division of Omaha Standard is a leading manufacturer of hydraulic liftgates (tailgates) for pickups and light to medium duty trucks. Our cable type liftgates have 1,000 lb., 1,300 lb., or 1,600 lb. capacities, the direct lift (no cables) liftgates have 1,300 lb. or 1,600 lb. capacity for full-side pickups and service bodies, while the rail lift models are rated at 1,600 lb. and 2,000 lb. capacity.
  • In addition to these standard products, Omaha Standard also builds custom units such as line bodies, crane bodies, and cargo bodies.

Scissor Hoists

Omaha Standard offers seven single cylinder scissor hoists made from special high strength steel. These light weight hoists are all double acting[1] (power up and power down) with heavily chromed and polished piston rods. A P.T.O. driven direct mount gear pump is standard on all models. Electric/hydraulic, piston, or remote mount gear pumps are available as options. All pivot points have lubrication fittings for easy maintenance. A pre-installed, integral body prop automatically positions itself and stores securely out of the way when not in use. All Omaha Standard hoists have a full-width, heavy structural angle rear hinge. The “drop-hinge” design of our scissor hoists results in a very low mounting height eliminating the need to cut body cross members. Installation is fast and easy with applications covering bodies 8’ to 20’ long and cab-to-axle dimensions of 60” through 174”.

Olympic Hoists

Omaha Standard offers six different models of Olympic series telescopic conversion hoists made from high-strength steel. The unique patented design results in greater “torsional stability” than any other hoist on the market (less body twist under uneven loads). This means a safer working environment. Single acting or double acting (power up and power down), they all have high polished, hard-chromed telescopic cylinders for durability and long wear. Self-centering cylinder saddles reduce the possibility of seal or cylinder wall damage and patented frame stops prevent the cylinder from bottoming out and the hoist from going over center. A PTO driven direct mount gear pump is standard on all models. Remote mount gear or high pressure, positive displacement piston pumps are available as options. All pivot points have lubrication fittings for easy maintenance. The 144 HD is completely grease-free with composite bearings in all joints, including the rear hinge. Olympic hoists have more lifting capacity and longer reach than other stabilizer-type hoists. This means greater capacity and a far forward lift point. The low profile and reversibility (mounting in either direction) provide quick, easy, and flexible installation. Applications cover body lengths from 15’ to 28’, cab-to-axle dimensions of 120” to 174”, and cab-to-trunnion dimensions of 102” to 246”.
