Hydraulic excavator ZX135US-7 SRF

compact

Overview
This short-radius compact excavator is engineered for tunnelling and other confined-space works where a reduced tail swing and short boom/arm are required. It is built for continuous underground operations and accepts a range of heavy-duty attachments normally fitted to larger 20-tonne machines. The machine can be lowered into below-ground sites by crane and can operate in tandem with clamshell telescopic-arm excavators.

Key features
