The
DMF ROTO 180 is a rotating dump body that permits its user to deposit
the contents of the bed anywhere within a 180° arc. Between the dump
body and the truck chassis lies its hydraulically actuated sub-frame
which is the heart of the ROTO 180. It is a two piece structure that
joins the truck and dump body by means of a massive, durable 43"
industrial roller bearing. The sub-frame also houses multiple hydraulic
cylinders and a custom designed manifold that controls the lift, swing,
and tailgate release functions via an in-cab panel. The standard ROTO
180 is a 12' long, 10-12 cu yd dump body, however there are also options
for 10' long, 5-7 cu yd and 14' long, 12-14 cu yd models.
The following information is furnished to
establish the general chassis guidelines for installation of a DMF ROTO
180 rotating sub-frame. However, it is not intended to be a complete
truck specification sheet. Consult with DMF or your truck equipment
dealer to assure that all equipment will operate safely with the chassis
you are ordering.
When purchasing a chassis for a DMF ROTO
180 please keep the following information in mind:
For a standard 12' long 10-12 cu yd body to be mounted on a chassis
having a standard tandem rear suspension, a minimum CT of 87" is
required. The truck will also need sufficient after frame to mount the
rear railgear bracket.
The truck will also require a PTO and
hydraulic pump capable of producing approximately 21 GPM of flow at
2,000 PSI. The truck should also have a 30 gallon hydraulic reservoir
and a suction filter to keep the system clean. An underframe exhaust
system is preferred. However, some stack systems are acceptable if they
do not obstruct the cab shield and allow rotation of the dump-body past
the cab.
Raildogs are
required when the DMF ROTO 180 is used in conjunction with RW-1630 railgear. Manual raildogs
require one foot of clear frame in front of the rear tires for mounting
and operation. Hydraulic raildogs need 24” of clearance. Battery boxes
and/or fuel tanks may need relocation to accommodate raildog
installation.
