DMJ140H Tracked Mobile Jaw Crusher: Flexible and Cost-Effective Primary Crushing Solution

DM Dual-Power Track-Mounted Primary Crushing Plant for On-Site Rock & Waste Processing, Rapid Site Mobility to Cut Operational Expenses

The DMJ140H tracked mobile jaw crusher is a high-performance dual-power mobile crushing unit developed by DM (Shanghai Dongmeng Heavy Industry) for primary crushing tasks. It is widely used in quarrying, tunnel muck disposal, construction waste recycling and aggregate production.

Unlike stationary crushing plants requiring lengthy foundation construction and expensive relocation, the DMJ140H is equipped with an innovative **diesel / mains dual power system**. Where grid electricity is available on site, the machine switches to electric drive to cut fuel expenditure, reduce noise and carbon emissions. In remote mine sites without power supply, the onboard diesel engine takes over to sustain continuous crushing. The two power modes can be switched easily, balancing mobility for remote sites and low-cost eco-friendly operation for electrified work zones.

The machine features a fully hydraulic tracked chassis and European high-efficiency jaw crusher. It requires no complex site preparation and starts operation immediately upon arrival, enabling on-site crushing and eliminating high haulage costs for bulk raw stone. Wireless remote control allows a single operator to maneuver the crawler for relocation on rough terrain and loading/unloading from flatbed trailers. Its deep V-shaped crushing chamber offers large feed capacity to process hard rock such as granite and basalt. Hydraulic wedge CSS adjustment is safe and convenient, minimising downtime. Heavy-duty frame, forged heavy eccentric shaft and robust spherical roller bearings guarantee stable performance under heavy loads and lower maintenance frequency, delivering excellent long-term economy.

As an original equipment manufacturer, **DM owns full in-house R&D, machining, assembly and testing capabilities**. As a high-tech & specialised enterprise, DM holds independent intellectual property rights for core crushing components. All key parts are processed internally and inspected under ISO quality management standards, avoiding quality risks from simple outsourced assembly. Custom upgrades are available for cold, rainy or high-dust environments. The modular structure enables easy containerised shipment for global projects. A large spare parts warehouse and worldwide field service team support commissioning, regular maintenance and rapid breakdown response to reduce customer downtime.
