Wipro's stabilising NUMMI front tipping gears have been designed
not only for lifting but also for giving stability during tipping.
For this reason, they are well suited for vehicles with long bodies
or when the body alone is not rigid enough for stable tipping.
Maximizing front axle payload
In the NUMMI JTC and JTD models, the cylinder is attached to the
body with lifting arms that absorb vibrations during transport and
allow the flex between body and chassis. Because of this attachment
method only a small space is needed for the tipping cylinder
between the cab and the body. This allows the body to be brought
further forward to fully utilise the front axle capacity. The
difference between the JTC and JTD models is the type of attachment
on the bottom end.
The NUMMI DFC model is equipped with a cover tube
with which it is attached to the body. The cover tube prevents
contaminants entering the cylinder during driving. The DFC
model is suitable for long bodies and large loads because the
design and dimensions of the cylinder tubes provide a great
stabilising effect during tipping.
The NUMMI DFE cylinder is attached from the top directly to the
front wall of the body meanign the front wall needs to be sloped.
This attachment method enables the tipping gear to be lightweight,
giving maximizing payloads. The DFE model has the same
cylinder tubes as the DFC model so it is also suitable for
heavy-duty work which requires increased stability.
Tough tipping gear
NUMMI cylinder are equipped with double seals ensuring no
leakage even in freezing temperatures. Plus, all cylinder tubes in
these tipping gears have been hard chrome-plated. Because of their
reliability, Wipro's stabilising NUMMI front-end tippers are
popular on heavy-duty dump trucks as well as with semi-trailer
