Final drive for PC1250

I. Input power matching

-Hydraulic motor type: 2 axial piton motors(integrated parking brake),directly driving the reducer.

-Travel circuit pressure:

34.3MPa(343Bar), providing high-torque input capability.

-Main pump flow rate: 2x494L/min, ensuring stable power supply.

II. Output characteristics

-Travel speed:

-High speed: 3.2km/h(PC1250-7/8) or 3.3km/h(PC1250-11R).

-Torque capacity:

-Designed to match machine operating weight(106500-119700kg) and maximum digging forces(bucket:48800kgf; arm:42000kgf), with rated output torque exceeding 40000N.m.

-Reduction ratio: Not publicly disclosed, but estimated at 80:1-100:1 based on low-speed travel and track dimensions(industry empirical data).

3. Intergrated braking system

-Hydrauclically released parking brake(brake pressure≥3.5MPa), ensuring safe sloe parking.
