Caterpillar launch new H-series wheel loaders

Earlier this year Caterpillar replaced their mid-size (18–26 tonnes) G-Series II wheel loaders with new H-series models — the 950H, 962H, 966H and 972H — designed to handle a wide range of tasks in construction, aggregates and bulk materials handling.

The new machines feature a number of key changes to enhance productivity and reduce owning and operating costs. Among these changes are new EU Stage IIIA emissions-compliant Cat engines featuring ACERT technology, together with a new load-sensing hydraulic implement system, which works more efficiently giving up to 7% improvement in fuel consumption and a 20% increase in lift force over the previous models.

As well as improved efficiency, the H-series wheel loaders also offer enhanced operator comfort, serviceability and reliability. Key changes include electro-hydraulic implement controls with simultaneous lift and tilt capabilities, a 5° forward-inclined left access ladder, a new cooling system, centralized hydraulic and electric service centers for improved maintenance, and ground-level access to daily and regular maintenance points.

Meanwhile, in the heavier size range, Caterpillar’s 31-tonne 980G Series II wheel loader has now been replaced by the new 980H featuring improved drive-train control and ACERT engine technology.

The 980H employs electronic clutch pressure control (ECPC) for precise control of pressure and timing, resulting in smoother transmission shifts, extended component life and enhanced operator comfort. Serviceability has also been improved with filter porosity reduced from 33 microns to 6 microns and an extended trans-mission filter change interval of 1,000h.

The machine also features a new next-generation modular radiator (NGMR), which replaces the advanced modular cooling system (AMOCS) used on the previous model, as well as a full-width, swing-out air-conditioning condenser and oil-cooler core.

The 980H is powered by an EU Stage IIIA-compliant Cat C15 ACERT engine, which delivers a gross power output of 261kW (351hp) and is electronically configured to provide a constant net horsepower throughout the operating range for enhanced productivity and fuel efficiency.

Fuel efficiency is further improved by an engine idle management system (EIMS), which allows users to change idle speeds to best suit the application. The system, which has four settings – hibernate, work, warm-up, and low voltage mode – is said to reduce fuel consumption by up to 40% when idling.

Operator comfort has also been enhanced on the 980H with improved cab sealing and access, and reduced sound levels within the cab. Additional sound insulation reduces the exterior sound level from 111dB to 108dB.
