Valve Maintenance Truck Package

Knapheide Custom Service Body with Integrated Wachs Valve Maintenance Skid (SB Service Body VMS)

Wachs has partnered with Knapheide to create the most efficient and complete valve maintenance truck, equipped with maximum storage and delivering unparalleled power and versatility.

To begin, order your cab chassis fleet vehicle from GM, Ford or Ram with a minimum rating of 19,500 GVRW, and a cab to axle length of 84 inches. When specifying your vehicle, a 220 amp alternator is the minimum requirement to operate the custom service body's included power invertor. To run the invertor to its full capacity, a high capacity or dual alternator arrangement should be considered. Upfitter switches and a reverse camera are also vehicle requirements.

Drop ship your truck to Knapheide in Quincy, IL, upon delivery of your vehicle Knapheide will upfit the custom service body onto your cab and chassis. They will then install Wachs Valve Maintenance Skid for Service Bodies (Standard SB VMS), available with diesel or gasoline power, to the custom service body, complete with all mechanical, fluid and electrical connections, ready for pickup. Wachs Utility Products has no involvement with the truck chassis cab itself, beyond truck ordering recommendations and specifications.

Choose from the options that best fit your needs. Wachs Standard SB VMS Skid, combined with Knapheide's customized service body professionally upfitted by Knapheide, creates the industry's most advanced valve maintenance truck. You specify and order your truck cab and chassis, have it delivered to Knapheide and we do the rest. Note the service body and upfitting, as well as the Standard SB VMS (skid system) is unique to each truck brand and engine type.
