The CR240EG plateau mining dump truck, independently developed by CRRC Datong, is a 220-ton electric drive mining truck specifically customized for plateau environments. The frame features a cast-welded combined box section structure, with key stress points designed as a cast structure. The carriage features a welded structure with lightweight design, and both sides of the bottom plate are of "U"-shaped structure, which reduces the weight of the carriage and prevents the adhesion and retention of goods. The hydraulic system uses an electric brake pedal to control the dual-circuit hydraulic proportional valve, realizing accurate brake pressure control and quick response of front and rear axles. The front suspension is of MacPhersan type, and the rear axle adopts a four-link connecting structure. The CR240EG mining dump truck features key components such as the converter cabinet, resistor cabinet, wheel reducer, main generator, and traction motor, all designed and equipped internally by CRRC. It includes a plateau-type engine capable of operating at altitudes of 5,500 m, paired with a reliable electric transmission system. With a rated load of 220 tons and a top speed of 55 kilometers per hour, it delivers high mobility and efficiency, meeting the transport demands of open-pit mines and large-scale water conservancy and hydropower projects in plateau environments.
