By:SourceFactoriesShandong Yunqi machinery sales Co., LTD is now offering the ZL50 transmission planetary gearbox for excavators to global buyers. The unit, priced from US$1,300 to US$1,350, is engineered for 154 kW input power and rated input speed of 2200 r/min…
Applications & Markets
Excavator fleets operate under punishing cycle loads, where a transmission failure can idle a machine for days and inflate total cost of ownership. Buyers sourcing replacement drivetrain components for ZL50-class wheel loaders and excavators weigh three factors heavily: torque capacity, oil pressure stability, and supplier responsiveness. The ZL50 planetary gearbox from Shandong Yunqi machinery sales Co., LTD enters this market as a direct-fit transmission option for earthmoving equipment. The unit’s rated input speed of 2200 r/min and 154 kW specification align with mid-size excavator power requirements, while forward and reverse ratios of 0.578/2.155 and 1.577 support controlled low-speed digging and higher-speed travel. Applications listed by the supplier span machinery, agricultural machinery, marine, and vehicle powertrains, but the ZL50 nomenclature points to wheel-loader and excavator duty cycles. With a stated monthly production capacity of 30,000 units, the company signals readiness for volume replenishment programs.
Product Description
At the core of the ZL50 is a single-step planetary gear set with a three-ring/cycloidal/coaxial layout. Hardened tooth surfaces extend wear life under repeated torque reversals. The vertical installation type suits compact engine bay layouts, while the torque converter manages power distribution and direction changes. Buyers evaluating this gearbox should note the following supplier-listed parameters:
