Heavy Duty Front Loader

Especially suitable for working in mine with heavy load, the JGM757-III heavy duty front loader works stably and reliably by opening up new path in the mountain and bearing heavy load in mine.

Performance Features
1. High Working Efficiency
A. The product is fitted with the automatic flat device for the working device which needs short action cycling time and enables high working efficiency.
B. The centring arrangement for the articulated position and small turning radius endow the product with high mobility and flexibility.
C. Compared with the counterpart, the product is manufactured with smaller overall length of only 7.782m and larger weight of 17.3t, leading to higher working efficiency.

2. Large Power
A. The heavy duty front loader adopts the single rocker arm Z-form reversal mechanism and optimized working device to ensure large lifting and breakout force.
B. The single-stage 4-element twin turbine torque converter, which is conducive to reducing the number of gear, matches with the transmission gearbox and engine rationally. That can ensure large traction force.
C. The high efficient and energy saving dual pump confluence hydraulic system has good dynamic property.
D. The engine of the product is the Weichai Landking Generation II low speed type having stronger power.
E. Fitted with our 50 heavy duty drive axle, the product has ultra long wheel base, large bearing capacity and good stability.

3. High Reliability
A. The single rocker arm mechanism, long wheel base, high-strength working device and frame work together for guaranteeing the reliability of the heavy duty front loader.
B. The above mentioned 50 heavy duty drive axle works with high reliability and stability.
C. The high-level electrical element, wire and sheath employ the flame retardant material for boosting the reliability and durability.
D. The added device of hydraulic oil cooler strengthens the adaptability of the product working in harsh environment.
E. The front and top cover of the cab is processed with overall profiling to maintain high structural strength and reliability.
F. The rear machine cover exploits the overall frame type structure. It has high structural strength and good reliability.
G. The negative pole of power supply switch is put into service. When the machine doesn't work for a long time, it switches off for reliable and stable operation.
H. The departure angle of the increased balance weight can get to 30°, making the heavy duty front loader go up and down the slope more easily.
I. The Weichai Landking Generation-II low speed engine plays an important role in maintaining the reliability of the product.
a. Outputting large torque and traction force, the adopted Weichai engine reduces the fuel consumption and elevates the efficiency comprehensively.
b. The fuel system protector has many functions for keeping the normal work of the engine from different aspects.
I. The engine with the same grade diesel oil relating to the temperature can work normally even under special weather and environment conditions. For example, under the environment with the temperature of 0℃ or so, the engine can still work normally even being added with the 0# diesel oil.
II. The fuel system protector can pump the oil and exhaust the air, which helps shorten the startup time of the engine and increase the lifespan of the startup elements.
III. The impurities and moisture are filtered by the trustworthy dewater filter core for bringing down the failure rate of the fuel system.
c. The electromagnetic thermostatic fan can automatically adjust the fan speed, which has the following functions.
I. The thermal equilibrium of diesel engine is improved and the replacement cycle for the piston, piston ring, piston pin and cylinder liner is extended.
II. The fan's useless power consume is effectively reduced to save fuel.

4. More Safety
The heavy duty front loader is equipped with the reversing alarm device to prevent the occurrence of accident during the reversing process.

5. More Comfort
A. The top, rear and side parts of the cab interior are constructed from the new GFP material pressed through the steel mold, creating an elegant interior environment.
B. In addition to the spacious interior and broad vision field, the operating devices in the cab are arranged rationally for convenient operation.
C. Due to the electromagnetic thermostatic fan of the engine, the vibration of the engine is reduced to improve the operating comfort.
D. The 4-point elastic suspension and bi-directional shock absorption of the cab make the damping effect attain more than 85%.
E. The floor plate of the cab is formed through the numerical control technology by using the 6mm steel plate in the overall blanking process, which can effectively keep the noise out. Meanwhile, the sound-absorbing material for noise reduction and floor mats for sound insulation are employed for weakening the reverberation in the cab. Then, the fatigue of the operator can be relieved.
F. The cab of the heavy duty front loader is also furnished with the front air conditioner with the defrosting function.

6. Easy Maintenance
A. The large maintenance space for the design of wing type machine cover side door provides more convenient access to maintenance.
B. The overall window on the cab is opened backwards for providing more convenience.
C. The accessories of the product have high universality for maintenance.

7. Long Lifetime
A. The centered articulated position and the overlapped front and rear tyres' track are propitious to the extension of the lifetime of the tyres.
B. The dustproof structure for the key articulated positions can keep a long service lifetime of the pins.
C. By using the large flow paper filter element for hydraulic oil suction and returning, the cleanliness of the hydraulic system can be maintained and the failure rate of the hydraulic elements can be reduced, thus helping increase the service lifetime of the heavy duty front loader.
D. The integral quenched cutting plate and bucket tooth are more wear resistant and can serve in a longer time.

8. Diversified Configuration
The working device with different bucket capacities for matching ordinary arm and high dumping arm is available.
A. Dongkang 6CTA8.3 or Weichai Landking Generation-II Diesel Engine
B. Meritor Drive Axle
C. Cooling or the Heating and Cooling Air Conditioner
D. Automatic Weighing Device
E. Pilot Operation
F. Automatic Centralized Lubrication
G. High-level Driver's Seat (including armrest, headrest and safety belt)
