Three New Caterpillar® H-Series Small Wheel Loaders

Three new Caterpillar H-Series small wheel loaders - the 924H, 928Hz and 930H - feature the Cat® C6.6 engine with ACERT® Technology for responsive power and low emissions.

The 924H and 930H feature the VersaLink loader linkage, which combines Integrated Toolcarrier versatility and parallel lift. The two loaders now have standard third function hydraulics for operating hydromechanical tools. The 928Hz retains the traditional Z-Bar linkage.

All three loaders also feature the H-Series cab and operator station, designed for easy access and egress and for efficient operation throughout an entire shift. The H-Series loaders also have new heavy-duty hydraulic coolers and brushless alternators for enhanced reliability and extended durability.

The Cat C6.6 is rated at 128 hp in the 924H and 149 hp in the 928Hz and 930H. It has a flatter power curve and is more silent than previous models and meets EPA Tier 3 off-highway emissions regulations.

The engine also has features to reduce maintenance requirements and increase uptime. Oil change intervals are 500 hours. The self-tensioning serpentine belt is reliable, and the electric fuel priming pump eases maintenance. All regular service points are accessible from ground level on the right side of the engine.

A single, low-effort joystick for lift and tilt functions also integrates directional and transmission control for reduced operator fatigue. An optional joystick combines lift and tilt functions with third function auxiliary hydraulic controls. This allows the operator to maintain control of the loader linkage while operating hydromechanical tools such as buckets with top clamps.

The 930H and 928Hz can be equipped with log skidder tires for improved traction and soft underfoot conditions. Underground utility contractors often use such a configuration. New wide fork carriages suitable for handling pipe and a new multi purpose bucket will be available with the skidder tire configuration.
