Komatsu has introduced its WA700-8 wheel loader, featuring advanced engine technology and an updated 12-cubic-yard bucket that enables it to fill a 70-tonne haul truck in just four passes.

Weighing 214,069 pounds, this loader is powered by a 773-horsepower Tier 4 Final diesel engine, delivering 8 per cent more gross power, 8 per cent better fuel efficiency, and 15 per cent more torque compared to its predecessor.

The automatic transmission comes with an electronically controlled modulation valve, adjusting the gear selection based on travel speed, engine speed, and other factors. Operators also have the option to use manual shifting mode.

Komatsu’s SmartLoader Logic engine control system optimises engine torque in different work phases, helping minimise fuel consumption. For instance, digging in V-shaped loading requires higher torque, while driving with an empty bucket requires lower torque.

The new Hensley bucket has been redesigned for easier loading and reduced material spillage. The added spill guard improves operator visibility, and sweeper wings protect the front tires, resulting in a 6% increase in lifting force and rated load over the WA700-3.

On challenging terrains, the variable traction control system prevents tire slippage, enhancing safety and extending tire life, especially in wet or slippery conditions.

Sebastian Witkowski, product manager, commented, “The WA700-8 is ideal for quarry operations, offering improved productivity and efficiency with a heavier operating weight, higher tipping load, and larger breakout force.”
