The Hitachi ZX135US-5 SRF excavator is designed for tough applications in tight spaces
233 Hitachi says that its new ZX135US-5 SRF excavator is a tough and durable machine designed for safe working in difficult conditions. This robust excavator is designed with a short tailswing that allows it to work in tight spaces. Meanwhile it also has a short stick and boom made from heavy duty steel. The machine is more compact than a conventional excavator and suits use in tunnelling projects. It can be lowered into position on sites below ground level using a crane and has lifting brackets provided as standard on the boom and counterweight. The machine is also said to be easy to transport.

The short boom and arm of the ZX135US-5 SRF, and a reinforced bucket linkage, enables it to be fitted with attachments that are suitable for 20tonne machines.

The front end has been beefed up to protect it from falling objects. The cylinders are located under the boom and arm, and an integrated cylinder guard on the arm protects the bucket cylinder. It has a ROPS pressurised cab and good all-round visibility with help from a rear-view camera.
