4-Ton Compact Crawler Excavator PX-40

Product Overview

The PX-40 is a 4-ton compact crawler excavator that bridges mini-class agility and mid-size productivity for confined and continuously worked sites. Its compact structure keeps the machine productive in narrow jobsites while delivering the power needed for heavier earthmoving. With flexible configuration options and a range of available attachments, the PX-40 adapts to contractor fleets, municipal projects, utility work, and cab-operation conditions that demand all-day reliability and low operating cost.

Product Description

The PX-40 is engineered around a reinforced compact body that keeps the machine within a machine width of about 1700 mm, allowing it to work alongside walls, fences, and traffic lanes where larger excavators cannot fit. The powerhouse configuration includes Changchai 490 class diesel options around 34 kW, giving the compact chassis enough torque reserve for continued loading and trenching cycles without frequent rest or over-speeding.

With a maximum digging depth of approximately 2545 mm and a dumping height of approximately 3050 mm, the PX-40 is capable of productive trench and foundation work for a machine of its class. Its 0.20 m³ class bucket, optional attachment packages, and cab-oriented layout support reinforced, continuous earthwork in demanding site conditions, while service access and simple maintenance routines reduce downtime for contractors running multiple machines.
