Service Body Trucks

Signature-Series-1-leftsideSince 1976, Maintainer Corporation of Iowa, Inc. has developed its products to be the best in their class. We have continued to be the industry leader in manufacturing and sales of heavy duty customized service bodies, service body cranes and lube bodies. Over the years, new products have been introduced and existing products have been improved…all with the common goal of offering only the very highest quality, value priced, products to our customers…dealers and end users alike.

Our very first body design was called a BMT (Basic Maintainer Body) and was a flatbed with a behind cab mounted fixed boom crane. It was designed to fulfill a specific customer need to service equipment in the field.

The first one-ton pressurized storage system (PSS) Maintainer service body with 6,000 lb. capacity full hydraulic telescoping boom crane was introduced in the fall of 1981. In 1984, as a result of increasing demand, the company introduced a two-ton version with an 8,000 lb. capacity crane.

As our company continued to grow, its reputation for high quality market driven custom products led to the development of a two-ton lubrication body. The crane product line was expanded to include lift capacities of 3,000 through 14,000 lbs. and state of the art closed-center hydraulics were added to provide simultaneous multiple function operation. Since then, the list of product enhancements and custom options available has literally exploded.

Maintainer is truly a one-stop-shop with an enormous capacity to satisfy its customers…giving them what they want, at a fair price and superior return on investment. Maintainer is an exciting company with excellent products and committed people ready to serve you.


Maintainer’s Signature Series are models that have been configured to include Maintainer’s most commonly requested features. Although these models do not allow for much customer configuration as in a new custom body, the Signature Series bodies give the customer the best value on popular features as well as reduced lead times as many are being constructed for inventory.

The Signature Series bodies #1, #2 and #3 are all Mechanics Service Trucks featuring our premium quality Maintainer cranes with wireless controller. Each comes with an hydraulic 40-CFM air compressor with air kit, two DuaLock roll-out drawer sets, rear workbench push bumper, exterior flood lights (one permanent and one remote), interior compartment LED strip lights, and many other useful options and features. Each come with two hydraulic up/down outriggers for safety while performing the job.
