1.1 GENERAL DESCRIPTION
The DMF ROTO 180 system is a rotating dump body that allows the operator to deposit its load
anywhere within a 180° arc. Between the dump body and the truck chassis lays the
hydraulically actuated subframe. This two-piece structure contains a ball bearing that lets the
dump body rotate about the truck frame. Within the subframe are the hydraulic cylinders used
to lift and rotate the dump body. The standard ROTO 180 has a 12' long, 10-12 cubic yard
dump body; however there are also options for 10' long, 5-7 cubic yard and 14' long, 12-14
cubic yard models. Two control options are offered for the ROTO 180 system. See the following
sections for a description on both.
1.1.1 HydraForce Manifold ROTO 180 System Controls
The HydraForce ROTO 180 system is operated by a manifold mounted within the subframe.
Toggle switches, mounted in the cab, active 12 VDC solenoid valves to control the operation of
the manifold. The manifold controls the lift, rotation and tailgate functions of the dump body.
1.1.2 PVG Valve ROTO 180 System Controls
The PVG Valve ROTO 180 system uses a PVG valve block, mounted to the exterior of the
subframe, to control the hydraulic system. Proportional valves are used to smooth out the
movement of the lift cylinder and the rotation of the dump body. The system is controlled from
a keypad and joystick within the cab of the truck. It can also be controlled externally through
an optional wireless remote. All signals from these devices are routed through a PlusOne
control module. All major electronics and hydraulics are mounted outside of the subframe for
easy access and serviceability.

1.2.4 Safety Features
The ROTO 180 system has built in safety features to keep personnel safe and equipment
functioning properly. The tailgate is set to automatically release at 22° to prevent sudden
shifts in load that could tip over the truck. This function may be overridden by the operator at
any time however at their own risk. The dump body is restricted to a 40° lift angle to prevent
overextending the hoist cylinder and damaging the rear of the truck and rear Railgear. A swing
alarm sounds whenever the dump body is rotated. A safety strut is provided for use when
servicing the dump body.
