Modular mount for transit concrete mixer

A method of assembling a vehicle-mounted, self-contained, independent truck-mounted concrete mixer operating system and mounting said operating system to a vehicle chassis, the method comprising:

• constructing a completely pre-assembled front modular unit and a completely pre-assembled rear modular unit, with the completely pre-assembled front modular unit comprising all hydraulic and electrical components necessary for operation thereof and a front unit support structure which supports all components of the front modular unit, and the completely pre-assembled rear modular unit comprising all hydraulic and electrical components necessary for operation thereof and a rear unit support structure which supports all components of the rear modular unit, and wherein the preassembled front modular unit and the preassembled rear modular unit are each transportable as separate units;
• positioning said front modular unit on the vehicle chassis at a desired front mounting location and subsequently connecting said front modular unit to the vehicle chassis by coupling the front unit support structure with the truck chassis, and positioning said rear modular unit on the vehicle chassis at a desired rear mounting location and subsequent connecting said rear modular unit to the vehicle chassis by coupling the rear unit support structure with the truck chassis;
• and
• connecting a vehicle power take-off to the hydraulic system of the front modular unit, and connecting a control conductor of the vehicle to a control conductor connection of the front modular unit, and completing hydraulic connections, electrical connections and air connections between the rear modular unit and the vehicle, thereby allowing the front modular unit and the rear modular unit to be fully operational.

A method of assembling a vehicle-mounted, self-contained, independent truck-mounted concrete mixer operating system and mounting said operating system to a vehicle chassis having a pair of parallel main rail members, the method comprising:

• constructing a completely pre-assembled front modular unit comprising a pair of parallel spaced front support rails, a front drum supporting structure attached to and supported by the pair of parallel spaced support rails for supporting a first end of a concrete mixing drum, and a drum drive assembly coupled to the front drum supporting structure, the drum drive comprising a self-contained hydraulic system for causing rotation of the concrete mixing drum which comprises a hydraulic motor, a hydraulic fluid reservoir and hydraulic pump for supplying hydraulic fluid to operate the hydraulic motor, wherein the preassembled front modular unit is transportable as a separate unit;
• constructing a completely pre-assembled rear modular unit comprising a pair of parallel spaced rear support rails, a rear drum supporting structure attached to the pair of parallel spaced rear support rails for supporting a second end of the concrete mixing drum, a charge hopper for receiving materials to be mixed, a discharge chute arrangement for off-loading mixed concrete and an associated access ladder arrangement wherein the preassembled rear modular unit is transportable as a separate unit;
• positioning said front modular unit on the vehicle chassis at a desired front mounting location such that the pair of parallel spaced front support rails are placed upon and coalligned with the pair of parallel main rail members, and subsequently connecting the pair of parallel spaced front support rails and the pair of parallel main rail members to one another;
• positioning said rear modular unit on the vehicle chassis at a desired rear mounting location such that the pair of parallel spaced rear support rails are placed upon and coalligned with the pair of parallel main rail members, and subsequently connecting the pair of parallel spaced rear support rails and the pair of parallel main rail members to one another;
• and
• connecting a vehicle power take-off to the hydraulic system of the front modular unit, and connecting a control conductor of the vehicle to a control conductor connection of the front modular unit, and completing hydraulic connections, electrical connections and air connections between the rear modular unit and the vehicle, thereby allowing the front modular unit and the rear modular unit to be fully operational.
