Service Body Valve Maintenance Skid VMS, Diesel

Wachs Service Body VMS Valve Maintenance Skid is used in conjunction with the custom Knapheide service body.  Assembled by Wachs and shipped direct to Knapheide, it is upfitted following installation of the custom service body to your furnished chassis cab.

To begin, order your cab chassis fleet vehicle 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 300 amp or dual alternator arrangement is highly recommended. Upfitter switches and an in-cab reverse camera are also vehicle requirements.

The Service Body VMS Skid, Diesel is equipped with a long lasting Kubota 4 stoke diesel, matching the choice of engine in the chassis cab. It draws its fuel supply from the truck, eliminating the need for separate fueling of the SB Skid's diesel engine. Like our other skid platforms, all Wachs valve maintenance components such as the vac system, water supply, spoils tank and HPU come preinstalled and prewired to a steel skid, ready to bolt down to the custom service body, complete with all mechanical, fluid and electrical connections to the truck chassis cab.

The Service Body Skid can be optioned with a wide range of valve exercising machines, vacuum systems with powered spoils tanks, hot water systems and more. Typical equipment includes a powerful 500 CFM-11in Hg vacuum, a 250 gal spoils tank utilizing Wachs exclusive hydraulic slide, tilt & rear discharge, with a power latching rear door. Also standard is a 2.5 GPM@3000 psi pressure washer system and 80 gallon water tank, with an optional hot water system for colder climes.

A HPU (Hydraulic Power Unit) with a HTMA Class II circuit is included, with a 10 gal reservoir, and a fan cooled heat exchanger, producing up to 8 gpm @ 2000 psi to operate the ERV-750 and optional TM-7 and accessory hand tools such as breakers. A 50 foot hydraulic hose reel and programmable arrow board and work lights round out the equipment list of this utility workhorse.
