The Wachs Service Body VMS Valve Maintenance Skid is designed for integration with the custom Knapheide service body, creating a powerful and efficient valve maintenance solution. Assembled by Wachs and shipped directly to Knapheide, the skid is professionally upfitted after the custom service body has been installed on your supplied chassis cab.
Step 1: Specify Your Chassis Cab
To begin, order your chassis cab fleet vehicle with the following minimum specifications:
19,500 GVRW rating
84-inch cab-to-axle length
220-amp alternator (minimum) to support the power inverter; a 300-amp high-capacity alternator or dual alternators are recommended for optimal performance.
Upfitter switches and an in-cab reverse camera are required for functionality.
Seamless Integration
The Service Body VMS Skid, Diesel is powered by a reliable Kubota 4-stroke diesel engine, matched to the vehicle’s engine type. The skid draws fuel directly from the truck, eliminating the need for separate refueling. Like all Wachs skid platforms, it comes preinstalled and prewired, with valve maintenance components such as the vacuum system, water supply, spoils tank, and hydraulic power unit (HPU) mounted on a durable steel skid. The unit is ready to bolt down to the service body with all mechanical, fluid, and electrical connections preconfigured.
