Smooth transmission

Resource recovery specialist Suez has purchased seven Heil Farid front-end loader refuse trucks with Scania chassis, equipped with Allison Transmission’s fully automatic transmissions.

Allison’s 4000 Series is designed to make heavy-duty vehicles operate smoothly and efficiently, offering close- or wideratio gearing and up to seven speeds, including two overdrive ratios and a second reverse gear.

The 4500 model is rated up to 2,102Nm gross input torque and 500hp (373kW) gross input power.

“A fully automatic front-end loader was vital for us because of the high amount of close-quarter manoeuvring our refuse trucks have to do, with lots of shunting backwards and forwards during each 16-hour day,” said Brian Juffs, general fleet manager at Suez.

Allison transmissions use a patented torque converter instead of dry clutch, meaning that clutch repairs and replacements required by manual and automated manual transmissions are eliminated. The torque converter multiplies engine torque at launch, providing exceptional startability and improved acceleration.

Maximum efficiency between engine and transmission is also achieved because Allison’s transmissions change gear without power interruption.
