BENEFITS & FEATURES
|
- ACERT™ Technology maintains engine performance, efficiency and durability while reducing emissions
- Heavy duty components withstand all operating conditions
- Strong, solid structures built to last
|
RADIATOR
Brazed aluminum construction provides a stronger joint for maximum durability and resistance to leaks. The 6-fins-per-inch, square-wave core design decreases the chance of blockage and plugging.

EPA TIER 3, EU STAGE III COMPLIANT C7 ENGINE
ACERT Technology combines proven systems with innovative new technologies to precisely deliver fuel to the combustion chamber. It maintains engine performance, efficiency and durability while dramatically reducing emissions.
The Cat C7 with ACERT Technology is a 7.2 L displacement, 6-cylinder, electronically governed engine. Electronic fuel injection is provided through the well-proven Caterpillar hydraulically actuated, electronically controlled unit injection (HEUI) system. A wastegate turbocharger, equipped with a titanium wheel for improved durability, combined with air-to-air aftercooling (ATAAC) provides consistent high horsepower with increased altitude capability.

Control Throttle Shifting
Control Throttle Shifting regulates engine speed during high-energy directional changes for smoother shifting and longer component life.
|
POWERSHIFT TRANSMISSION
The IT62H continues to use heavy-duty powershift transmission technology proven on previous models and currently used up through the largest wheel loader built by Caterpillar - the 994F.
The planetary powershift transmission features heavy-duty components to handle the toughest applications. Built-in electronic controls enhance shift quality, productivity and durability.

Electronic Clutch Pressure Control
Electronic Clutch Pressure Control (ECPC) system modulates clutches individually to improve shift quality, component life and operator comfort. Adjustment is simplified with all solenoid valves externally mounted on top of the transmission housing.
|
AXLES
The IT62H axles are designed by Caterpillar for durability in all operating conditions. The front axle is rigidly mounted to the frame to support the weight of the wheel loader and withstand internal torque loads as well as external forces encountered throughout operation.
The rear axle is designed to allow ± 13° oscillation. All four wheels remain on the ground over uneven terrain providing excellent stability and traction.
|
Integrated Braking System
The Cat exclusive Integrated Braking System reduces axle oil temperatures and improves transmission neutralizer smoothness. IBS has a direct impact on durability of the axles and brakes especially in applications involving long distances and/or heavy braking.

STRUCTURES
The articulated frame design of the IT62H features a durable box-section engine frame and rigid four-plate loader tower that is robotically welded. Robotic welding creates frame joints with deep plate penetration welds and excellent fusion for maximum strength and durability.
|
Engine End Frame (EEF)
A full box-section engine end frame with hitch plates at the front end provides a strong, rigid structure that resists twisting and impact loads. The result is an extremely solid mounting platform for the engine, transmission, axle, ROPS and other accessories.

Spread Hitch
The distance between the upper and lower hitch plates is an important contributor to machine performance and component life. The Caterpillar spread hitch design provides excellent load distribution and bearing life. Both the upper and lower hitch pins pivot on double tapered roller bearings - improving durability by distributing both vertical and horizontal loads over a larger surface area. The wide opening also provides excellent service access.

Non-Engine End Frame (NEEF)
The non-engine end frame provides a solid mounting base for the front axle, lift arms, lift cylinders and tilt cylinders. The fabricated, four-plate loader tower absorbs the forces associated with loading, twisting and penetration.

Counterweight
The one-piece counterweight is integrated into the IT62H design and styling. This 4389 lb (1991 kg) counterweight incorporates the rear lights into the top of the structure.

8-Bar Linkage
This linkage provides parallel lift to keep the load level throughout the lift cycle - particularly important when using forks. Parallel lift allows the operator to concentrate on placing the load, instead of retaining it. Visibility to the work tool is excellent.
Larger tilt cylinders and a more robust linkage design improve breakout force and overall rackback capability. Rotary sensors for the lift circuit let the operator electronically set detent positions from the cab.
