Cat DP100N Specifications
The Caterpillar DP100N is a heavy-duty diesel-powered
pneumatic-tire forklift engineered for industrial operations requiring high
lifting capacity, consistent full-shift productivity, and long-term reliability
in harsh conditions. With a nominal load capacity of 10,000 kg (22,000 lb), the
DP100N is widely used in ports, steel mills, concrete plants, mining operations,
heavy logistics terminals, and multi-shift manufacturing environments.
Equipped here with the Perkins 1204E high-output industrial diesel engine, the
DP100N offers high torque at low engine speeds, low fuel consumption, stable
thermal performance, and compliance with Tier 4i/Tier 4 Final emissions
standards depending on configuration. The forklift incorporates a reinforced
chassis, large pneumatic tires, a heavy-duty planetary drive axle, a robust
powershift transmission, and a high-capacity hydraulic system designed for
continuous lifting.
Operators benefit from a spacious low-vibration cab, wide forward visibility,
ergonomic control layout, and smooth steering response. Maintenance technicians
appreciate the machine’s modular component arrangement, accessible engine bay,
wide-swing service doors, and extended-interval fluid systems. The DP100N is
built for continuous service in tough applications where uptime and operating
efficiency are essential.
The Caterpillar DP100N in this configuration is powered
by the Perkins 1204E industrial diesel engine, a 4-cylinder, turbocharged,
aftercooled engine engineered for high reliability and durability in
heavy-equipment applications.
