  • CR240E

  • Engine

    Features:

    ● MTU 16V4000C13L 2500HP engine

    Applicable to most of mines at present, and the power will not be reduced for the altitude of 4500m. By using MTU's second-generation high-pressure common rail fuel injection system, it has better fuel economy.

    ● Cummins QSK60-2S2500 2500HP engine

    Applicable to most of mines at present and equipped with modular common rail fuel system with dual-start electric motor and electronic precise control, it has better fuel economy.

  • Suspension

    Features:

    ● With Macpherson independent suspension structure

    ● Hybrid hydro-pneumatic suspension with advanced performance is adopted for suspended cylinder to reduce turbulence.

  • Electric wheel unit

    Features:

    ● Integrated with traction motor, wheel reducer, caliper brake and parking brake.

    ● The traction motor is designed to adapt to wind and sand environment, and the optimized bearing structure can reduce dust entry.

    ● NGW two-stage composite planetary gear train is adopted for wheel reducer.

    ● The full hydraulic caliper disc brake system meets the requirement of ISO 3450-2011.

    ● Real-time monitoring of vibration and temperature can be achieved by online monitoring system.

  • 冷却

    特点:

  • Braking

    Features:

    ● Full hydraulic caliper disc brake system

    ● The diameter of front wheel brake disc is 46 in (1168.4mm), designed with three sets of brake caliper

    ● The diameter of rear wheel brake disc is 28 in (711.2mm), two braking discs on each side, designed with single brake caliper.

    ● Integrated parking brake

    ● The service brake is used with electric wheel resistance slow braking, which is generally used when the speed is lower than 5Km/h.

    ● Front wheel brake, rear axle brake and parking brake can be used simultaneously in case of emergent braking.

    ● Meet the requirements of ISO 3450-2011 standard III and hydro-pneumatic suspension.
