Torque. Traction.
Total Control.
The drive axle is the muscle of your Reach Stacker. We supply OEM-grade parts for Kessler D81/D91 & Rockwell axles. From planetary gears to wet disc brakes, keep your fleet moving.
HEAVY DRIVE INVENTORY
The Planetary Advantage
Port machinery requires immense torque at the wheels. The Planetary Hub Reduction system multiplies torque right where it’s needed, reducing stress on the half-shafts.
Zhenke supplies precision-forged sun gears and planet carriers compatible with Sany & Kalmar Drive Axles. Our wet disc brake kits are sintered for high heat resistance during repetitive braking cycles.
INSIDE THE HUB: KESSLER D91
REDUCTION RATIO LOGIC
The planetary gear set multiplies torque by 3:1 at the wheel hub. Worn planet gears cause “clunking” noises and vibration.
- Sun Gear: Case-hardened steel to resist pitting.
- Needle Bearings: High-load capacity for 100-ton static loads.
- Ring Gear: Precision-cut internal teeth for silent operation.
SINTERED VS. PAPER FRICTION
Drag to see 3000-hour wear test results.
*Sintered bronze withstands 400°C+, preventing brake fade on heavy descents.
AXLE DYNO TEST
Witness our differential gears handling 50,000 Nm of torque.
