Upgrade your haulage in multiple ways

Leave the constraints of cables behind with Joy battery-powered haulage carts. Agile and versatile, particularly in low seam conditions, they offer you plenty of power to get the job done. Add the lithium-ion option for even more routing flexibility.

Up to 15% productivity increase in split-air super-sections*
96+% average machine availability
Average 1.5 million raw tons before re-build

Features and benefits

Powerful torque to each wheel

Brushless AC-traction motors drive each wheel independently and are designed to deliver maximum torque. Your operators enjoy excellent steering, smooth operation and strong performance on steep inclines. Regenerative braking enhances control on descents.

Extra traction when you need it

When conditions require extra traction, operators can hold down a button on the joystick to engage the trailer wheels for all-wheel-drive. No need to worry about problems with complex drive shafts, chains or sprockets.

Nimble in tight spaces

Electronically activated steering assist for smooth-and-easy steering while relieving stress on motors, drivetrain and suspension assemblies.

Upgrade to lithium-ion technology

The first lithium-Ion battery in soft rock mining is designed to boost productivity with 75% faster charge time, and much lower maintenance versus traditional lead acid technology. Contact your Komatsu representative for availability.

Haul more, charge less

Pursue higher productivity with the Joy lithium battery charging option. Two hours from discharged to full charge. No cool down period. A partial charge still provides significant haulage ability. No ventilation required.

Manage battery power more effectively

A gauge in the cab helps your operators monitor battery capacity. In the event of low remaining capacity, the system reduces features to conserve energy, so the operator can return to the charging area.

Save time with auto bed retract

After off-loading, the ejector bed retract sequence is completely automated and takes place while your operators tram back to the miner. This simultaneous tram and retract can save significant time and allow more trips during a shift.

Stay productive in rugged conditions

Your operators will appreciate the Joy battery hauler’s 25 degrees total full-up to full-down vertical articulation between the midsection and the trailer assembly. They’ll maintain excellent maneuverability and comfort, even in rugged conditions.

Operator visibility

Operators can perform more quickly and safely when they can easily see what’s in front of and behind the hauler. Optional forward and rearward FLIR cameras, mated to monitors in operator compartment, help operators be sure of their surroundings.
