Product Introduction
The Puhua 640 Wheel Loader is a high-performance 4-ton loading machine designed for efficiency, reliability, and operator comfort. Equipped with a Weichai WP6G175E22 Euro II engine delivering 129 kW of rated power and 640 N·m of torque, this model provides strong power output with excellent fuel economy.
The loader features a central articulated frame for outstanding maneuverability and lateral stability, making it easy to operate even in narrow working areas. Its full hydraulic steering, power shift transmission, and pilot hydraulic control system ensure smooth and responsive handling during operation.
The twin-pump hydraulic system intelligently merges the flow of the working and steering pumps, enhancing lifting and breakout forces while maximizing fuel efficiency. A robust air-over-hydraulic braking system with disc brakes on all four wheels ensures reliable stopping power and high safety in any working environment.
The steel engine covers offer durability, ease of maintenance, and a sleek exterior appearance suitable for demanding job sites.

Application Scenarios
The 640 Wheel Loader is widely used in multiple industries, including:
Construction – for loading, unloading, and earthmoving on urban construction and infrastructure projects.
Mining & Quarrying – for material handling, stockpiling, and ore transportation.
Agriculture – for handling feed, grain, and other bulk materials.
Road Maintenance & Municipal Works – for clearing, leveling, and snow removal tasks.
Logistics & Material Yards – for loading bulk cargo and gravel in ports, warehouses, and freight terminals.
Its high breakout force, strong traction, and durable structure make it ideal for both heavy-duty and medium-intensity operations.
Packaging & Shipping
To ensure safe and efficient transportation, the Puhua 640 Wheel Loader is carefully prepared for export according to international shipping standards:
Each unit is cleaned, inspected, and securely fastened before shipment.
Main body and bucket are fixed to prevent movement and abrasion during transit.
Key components are protected with anti-rust coating and waterproof wrapping.
Standard loading options include one unit per 40HQ container (partially disassembled) or bulk shipment/Ro-Ro vessel for large orders.
All packages are clearly labeled with model, serial number, and shipping details for easy identification and customs clearance.
This packaging and shipping method ensures that each loader arrives in excellent working condition and is ready for quick assembly and operation upon delivery.
