product description

Extreme Cold Version

1.All critical structural plates use Q355D and Q355E grade steel. Q355E steel plate provides excellent low-temperature performance,maintaining good toughness and ductility even at-40°C, making it ideal for cold regions or applications subject to low-temperature impact loads.

2.The electrical system is supplemented with heaters; all cables inside the cabinet are replaced with low‑temperature‑resistant cables; the cabinet structure uses Q355ME cold‑resistant steel plate.

3.The power pack uses Q355ME cold-resistant steel plate;the motor is a low-temperature motor; the cable is a low-temperature cable; the seals are cold-resistant seals; the pressure gauge is a cold-resistant silicone oil pressure gauge; the level gauge is made of cold-resistant acrylic; the radiator plate is low-temperature resistant; the hydraulic oil tank is equipped with a heater; the hydraulic lines are equipped with heating tape; the electrical cabinet is equipped with a cabinet heater; and the engine is equipped with a water jacket preheater and a diesel preheater.

Product characteristics

01

Efficient Crushing

The feeder system utilizes variable-frequency speed regulation to ensure higher crushing efficiency and stability of the main unit. The crusher motor features variable-frequency start-up and an independent air intake/exhaust system, fully considering dust protection, heat dissipation, vibration isolation, and waterproofing for fail-safe electrical circuitry. The dual-cavity crusher unit provides a high crushing ratio and excellent product gradation, suitable for medium-hard materials such as limestone and sandstone.

02

Intelligent Walking System

A heavy-duty crawler chassis adapts to complex terrain, enabling autonomous mobile operation without fixed installation. The walking system is controlled by load-sensing pumps and proportional valve groups, achieves automatic deviation correction and stepless speed control during movement.

03

Dual-Power Supply

Supports both mains power and generator sets, accommodating different working conditions to ensure continuous production.

04

Remote Intelligent Control

The CFS (Constant Feed System) provides fully automatic crushing process control, significantly reducing equipment maintenance time while maintaining high output. Wireless remote operation minimizes the need for on-site operators. The intelligent, automated electrical control system includes self-diagnostic functions and safety interlocks to ensure safe and reliable equipment operation.
