XCMG XE135F Forestry Excavator

Overview

The XCMG XE135F is a 17.7-ton forestry excavator built for soft-ground timber and forest-site work. It combines an Isuzu BB-4BG1 engine, a 20-ton-class undercarriage and 960 mm wide single-grouser forestry tracks, giving it strong traction and better passability in muddy forest terrain.

XCMG positions the XE135F for forestry operations such as gathering, stacking, loading and unloading, with emphasis on high efficiency and fuel economy.

Key Features

• Forestry-ready undercarriage: 20-ton-class chassis, 960 mm wide single-grouser high-tooth tracks and a large-torque travel motor for muddy forest ground and climbing.
• Fuel-efficient powertrain: XCMG states that the Isuzu BB-4BG engine and large pump/valve configuration reduce engine speed into the fuel-economy zone, cutting energy use by more than 20% versus the previous generation.
• Strong traction: maximum traction force is listed at 190 kN, which XCMG describes as the highest in its class.
• Full-body forestry guarding: cab and body protection is designed to protect the operator and machine during forestry work.
• Hydraulic efficiency: double-pump constant-power negative-flow system, world-renowned main valve and instantaneous boost function for varied working conditions.
• Cooling and dust protection: advanced cooling system, plus dust-prevention nets for the engine and radiator.

Applications

Forestry gathering, stacking, loading and unloading, forest-road construction, soft-ground excavation, timber-site handling and other forestry-specific operations.
