Wheel Loader JINGONG JGM857E

Performance Characteristics

The machine has a wheelbase of 3300mm and a rear overhang of 1685mm, with a reasonable front and rear axle load distribution for excellent stability. The frame, based on years of market validation of traditional loaders and combined with finite element simulation analysis, significantly improves reliability. “High-performance permanent magnet synchronous motor technology is mature and highly reliable. The dual-motor system drive scheme separates the oil pump motor and the travel motor for independent control, delivering stronger power and higher energy efficiency. Compared to traditional diesel engines, the motor drive responds faster, operates more efficiently, and produces zero emissions, zero pollution, low noise, and minimal vibration.” The motor torque far exceeds that of traditional diesel engines, with ample power reserve. It directly connects to the transmission to drive the travel system, ensuring high efficiency and energy savings. The machine adopts a 60 loader fixed-shaft transmission with multiple gears, enabling different travel speeds and traction forces through various transmission ratios to meet diverse operational speed and working condition requirements. It features an upgraded Jin Gong heavy-duty 50E drive axle with four planetary gears, offering high structural strength, exceptional load capacity, long service life, and high reliability. The electronic control handle integrates gear-shifting functionality: the handle outputs position signals to the controller, which adjusts the working motor speed based on different actions. Fast charging technology supports 240kW charging piles, enabling a full charge in 1 hour. The brake pedal is equipped with analog electrical signal output, feeding braking actions back to the controller for energy recovery during braking, reducing brake system wear and improving energy utilization. The battery includes built-in heating and cooling systems with intelligent temperature-controlled liquid cooling to maintain optimal operating temperatures in real time, extending battery life. The newly upgraded Jin Gong cab features a large curved front windshield for a broad field of vision. Enhanced cab rigidity, improved sealing, optimized damper characteristics, and sound-absorbing materials effectively block dust and reduce noise. It comes equipped with air conditioning, a radio, and more. In addition to traditional combination lights, LED lights are added at the front of the cab and the rear engine cover. A reversing camera combined with an anti-collision bar further ensures battery pack safety.
