37-Ton Heavy Track Excavator XE370D for sale

Product Overview

The 37-Ton Heavy Mining Excavator is a heavy-duty workhorse tailored for high-intensity mining operations, featuring an operating weight of 36000 kg and a total power output of 210 kW. It adopts a mine-specific reinforcement design—including a thickened frame, reinforced bucket, and heavy-duty undercarriage—making it capable of withstanding the harsh conditions of open-pit mines, such as continuous rock impact and dust accumulation. The machine also integrates an intelligent fault diagnosis system that monitors key components (engine, hydraulic pump, and electrical system) in real time, sending alerts to the operator and remote management platform if abnormalities are detected, thus reducing unexpected downtime.

Product Features

Engine & Emission Compliance: Powered by a new-generation diesel engine with a large cold EGR (Exhaust Gas Recirculation) system and a DPF (Diesel Particulate Filter), it meets China’s National IV emissions standards without the need for urea injection. This design simplifies maintenance and eliminates the risk of urea crystallization in low-temperature environments. The engine also features a low-noise design (operating noise ≤85dB at 1m distance), improving the working environment for operators and nearby personnel.

Structural Reinforcement & Durability: The undercarriage is equipped with double-rib track plates made of high-manganese steel (Mn13), which have a wear resistance 50% higher than ordinary steel plates, extending track life to 3000+ operating hours. Full undercarriage guards prevent rock fragments from entering and damaging the track chain and rollers. The bucket (1.6-1.8 m³ capacity) is lined with a wear-resistant alloy layer (thickness 15mm) at the bottom and cutting edges, which can withstand 1000+ hours of ore loading before needing replacement.

Maintenance Convenience & Cost Savings: All fuel filters, oil filters, and hydraulic filters are centrally located in the rear pump room, allowing maintenance personnel to access and replace them quickly—reducing maintenance time by 40% compared to scattered filter layouts. An air pre-filter with a cyclone dust separation function removes 90% of dust from the intake air before it enters the air filter, extending the air filter’s service life by 3 times. Additionally, the machine’s hydraulic oil can be used for 5000 operating hours (with regular oil analysis), reducing oil change frequency and costs.

Applications

Large-scale open-pit mining operations, including iron ore, coal, and bauxite mining

Heavy-duty rock breaking and stripping tasks, such as removing overburden (soil and soft rock) to expose underlying ore layers

Mine waste disposal and site leveling, including transporting and stacking waste rock in designated areas and leveling mine haul roads

Auxiliary operations in mineral processing plants, such as loading crushed ore into conveyor belts and cleaning plant yards

FAQ

Q: What is the swing speed, and how does it contribute to efficient material transfer in mines?

A: The maximum swing speed is 9.8 rpm, which is 15% faster than standard 37-ton mining excavators. This fast swing speed reduces the time required to rotate the upper structure from the digging position to the dump truck, increasing the number of loading cycles per hour by 8-10—significantly boosting overall productivity in high-volume mining operations.

Q: How is operator comfort ensured during long shifts (e.g., 12-hour shifts) in mining environments?

A: The cab is equipped with a fully adjustable suspension seat (with lumbar support and heating/cooling functions) that reduces operator fatigue by absorbing vibration. Lightweight pilot controls with ergonomic design require minimal force to operate, reducing hand and arm strain. The cab also features Bluetooth connectivity for hands-free calling and a USB charging port for electronic devices. Additionally, a high-efficiency air conditioning system with dust filtration keeps the cab interior clean and maintains a comfortable temperature (18-26°C) even in extreme outdoor conditions (-30°C to 45°C).

Q: What is the ground clearance, and how does it protect the machine from ground debris in mines?

A: The minimum ground clearance is 550 mm, which is 20% higher than standard excavators in the same class. This high clearance prevents the undercarriage and hydraulic lines from being damaged by large rock fragments (up to 50mm in diameter) commonly found on mine floors. The undercarriage guards further reinforce this protection by blocking small debris from entering the track system.
