Working Arm: The national standard GB/T700-Q235B material is adopted, the tensile strength reaches 375-550MPa.

Hydraulic Cylinder: Fujian Shanli engineering machinery oil cylinders are used. The thrust of the oil cylinders can reach 4500N. The imported Parker seals are used, which have good sealing performance, long life and high reliability. Each joint adopts wear-resistant Koryo self-lubricating bushings, which have better wear resistance.

Bushing: For the bushing used in excavation, JDB solid graphite inlaid bearing (high-strength brass bushing) (ZCuZn25Al6Fe3Mn3) is selected, which has high wear resistance and good corrosion resistance, and reduces maintenance costs in terms of use and maintenance.

Hydraulic System

After several generations of manufacturing and upgrading, the overall design of the hydraulic system is much more reasonable.

The hydraulic system adopts two-stage control and is equipped with a hydraulic pilot joystick, which has characteristics of good proportional control and is easy and convenient to operate.

The hydraulic gear pump adopts the triple pump/double pump produced by Jinan 7423 Military Factory, which has strong wear resistance and pollution resistance, high efficiency and long service life.

The hydraulic system adopts a high-power air-cooled radiator to ensure that the working oil temperature of the whole system is constant.

The filter can control the pollution degree of the hydraulic system to protect the oil pump and other hydraulic components, thereby improving the cleanliness of the hydraulic system.

Conveying Part

1. Both sides of the trough, the bottom plate, and the pressure chain plate are all wear-resistant, which enhances the wear resistance of the conveying trough when conveying materials.

2. The main (/driven) sprocket is made of high-strength and wear-resistant alloy steel so as to improve the service life of the sprocket.

3. The scraper is made of Q345B material, welded and reprocessed. It is convenient to customize different types of scrapers according to customer's needs.

4. The scraper chain adopts double chains, which increases the transportation capacity of materials.

The chain adopts a chain pitch of 50.8mm, and the tensile load of this chain is 277KN; the chain plate adopts 40Mn, the pin shaft adopts 20Cr, and the roller adopts GCr15. Therefore, the life of the chain is longer than that of the belt.

Hydraulic System

1. The conveying motor adopts a low-speed high-torque motor produced by Zhejiang-Ningbo Yining, with a rated torque of 2433N·M.

2. Power leads, electrical circuit boards and the connecting wires of the electrical components are connected by wire lugs, and rubber cushioning and anti-vibration pads are installed on the electrical box and circuit boards to reduce loosening faults of the electrical circuit.

3. The electrical components used are selected from the manufacturers that meet the safety standards. The connecting wires used in each individual circuit are differentiated in color for easy maintenance.(only for non-explosion-proof models).

4. A circuit breaker is added to better control the output of the transformer.(only for non-explosion-proof models).

Explosion-Proof Electrical System

The main electrical components and electrical cables are selected from explosion-proof electric control boxes and flexible cables which are all approved by safety identifications.

Excavation Part

Pilot operation is adopted, which is more convenient and simple, and various operating joysticks are selected from Zhejiang Haihong Hydraulic.

Axle

Wheel-type walking, the walking speed can reach 1.3km/h, the transition speed is comparatively fast, and operation on multiple working surfaces is possible. Flexible turning, the front tires can be steered, four-wheel drive, and the tires are wear-resistant rubber (or solid) tires. The input joint is equipped with a buffer device, and the driving and parking are stable. The loader rear axles adopted are those made by the domestic axle manufacturer Fujian Jinjiang Liansheng Engineering Axle Factory/Isuzu.

Hammer Breaker

This machine can be equipped with an integrated breaking hammer, which can be break stones immediately when encountering large ones while removing the slag, which is convenient, fast and safe.

The hammer breaker can break stones and maintain the floor of the roadway and the bottom of the side; it can break large rocks and coal chunks after blasting without the need for supplementary blasting.

There is no need for blasting when excavating coal roadways or semi-coal roadways with hardness of f≤3.

Cable Reel

Special cable reels are adopted so they can realize the flexible and automatic retraction of cables when the equipment enters and exits the site, this saves manpower and material resources, improves safety, and has a high degree of automation, thus makes it free and more flexible for the loader to enter or exit the site. 60 meters can be installed.
