5 Ton Wheel Loader
Overview
The JGM857M is a 5-ton wheel loader designed for heavy-duty material handling in construction and aggregate sectors. It features a rated load capacity of 5,000 kg and an operating weight of 18,400 kg. The machine is powered by a Weichai engine with a rated power of 170 kW, supporting a maximum travel speed of 40 km/h. Its dimensions and turning radius are optimized for maneuverability in confined work areas.
The loader utilizes a planetary torque converter and a reinforced drive axle manufactured by JGM. It is equipped with 23.5-25 tires and offers a bucket capacity range of 2.4 to 4.5 m³. The machine achieves a maximum traction force of 165 kN and a bucket breakout force of 180 kN. These specifications support consistent performance in demanding loading and unloading tasks.
Key Features
5-Ton Rated Load Capacity
The machine handles a rated load of 5,000 kg. This capacity allows for efficient transport of bulk materials like sand, gravel, and crushed stone, reducing the number of cycles needed per shift.
170 kW Weichai Engine
Powered by a Weichai engine producing 170 kW, the loader provides the necessary torque for heavy lifting and sustained operation. This power output supports high productivity in continuous material handling tasks.
Variable Bucket Capacity
The loader accepts buckets ranging from 2.4 to 4.5 m³. This flexibility allows operators to select the appropriate bucket size for specific material densities and site requirements, optimizing payload efficiency.
Reinforced Drive Axle
The drive axle is a JGM-manufactured reinforced unit. This design enhances durability under heavy loads and rough terrain, reducing wear on critical drivetrain components during intensive quarry or port operations.
High Traction and Breakout Force
With a maximum traction force of 165 kN and bucket breakout force of 180 kN, the machine digs into compacted materials effectively. This ensures reliable performance when loading dense aggregates or hard-packed soil.
Compact Turning Radius
The minimum turning radius is 7,140 mm measured at the bucket outer edge. This dimension facilitates maneuvering in tight spaces such as stockpiles, narrow yards, and congested construction sites.
Planetary Torque Converter
The transmission uses a planetary torque converter. This system provides smooth power delivery and reduces mechanical stress on the drivetrain, contributing to consistent performance and lower maintenance demands.
Where the JGM857M Is Used
Quarry Operations
Ideal for loading crushed stone and raw aggregates from stockpiles. The high breakout force handles compacted material, while the robust axle withstands the vibration and impact of heavy-duty quarry work.
Construction Sites
Used for moving sand, gravel, and debris on large building projects. The 5-ton capacity and 40 km/h speed allow for rapid material transfer between excavation areas and processing zones.
Aggregate Yards
Suitable for blending and loading various aggregate sizes. The variable bucket options enable operators to adjust capacity for different materials, maintaining efficient yard management and dispatch rates.
Port Handling
Effective for loading and unloading bulk cargo in port areas. The machine’s traction and stability support precise positioning near vessels or storage containers, facilitating smooth material flow.
Block Yards
Used for moving heavy construction blocks and precast elements. The 5,000 kg rated load ensures safe handling of dense materials, while the compact turning radius aids in tight yard layouts.

How to Choose the Right Configuration
Evaluate the JGM857M for sites requiring 5,000 kg payload capacity. With a 2.4 to 4.5 m³ bucket range, it suits bulk materials like sand and gravel. The 170 kW engine supports continuous operation, while the 40 km/h travel speed helps move materials across larger job sites efficiently.
Check site dimensions against the machine’s 8,250 mm length and 7,140 mm turning radius. The 2,990 mm width fits standard access routes. Ensure ground clearance of 390 to 500 mm is sufficient for your terrain. The 3,460 mm dump height allows unloading into standard trucks and hoppers.
Verify transport logistics based on the 18,400 kg operating weight. The 23.5-25 tires provide stability on rough ground. Confirm that your receiving port and inland roads can handle this weight class. The reinforced JGM drive axle is designed for durability in heavy aggregate handling applications.
Daily Operation and Maintenance
Check tire pressure and tread depth daily to ensure stability and prevent uneven wear on the 23.5-25 tires.
Inspect the hydraulic system for leaks around the bucket and arm connections before each shift.
Monitor engine oil levels and check for unusual noises from the 170 kW Weichai unit during warm-up.
Clean debris from the radiator and air intake filters weekly to maintain cooling efficiency in dusty conditions.
