New XCMG LW300M Wheel Loader

Product Introduction

Energy-saving power transmission system

 

Engine: Yuchai, turbocharged with intercooler, electronically controlled high-pressure common rail, ECU intelligent control engine; equipped with a desert air filter with three-level filtration, capable of adapting to dusty working conditions; this engine not only has high reliability and adaptability, but also has the advantages of low fuel consumption and low emissions, and can be optionally equipped with a low-temperature start-up device. The emissions meet the Chinese Stage IV standards, and it is a high-quality product specially designed and manufactured for the working conditions of construction machinery.

 

Transmission and torque converter: The fixed-axis power shift transmission is connected to the single-stage single-phase three-element hydraulic torque converter, featuring four forward gears and two reverse gears, capable of meeting the speed requirements of different working conditions. This fixed-axis transmission has the advantages of high reliability, long service life, high transmission efficiency, simple structure, convenient manufacturing and maintenance, smooth shifting, and smooth engagement.

 

Hydraulic system

 

By adopting reliable single-pump分流 and load-sensing steering technology, using a high-pressure and large-displacement working pump， the time for three operations and time consumption are shortened. The integrated distribution valve is manually operated, with high system efficiency and energy saving and fuel economy.

 

In addition， based on the advantages of the hydraulic system of the LW300FV loader， the piping has been optimized and improved to facilitate installation and connection， while reducing pressure loss in the piping and the heat generation of the entire hydraulic system， thereby reducing faults.

 

Electrical System

 

The electrical system uses fully sealed connectors， significantly improving dustproof and waterproof performance. A centralized fuse box is adopted， making inspection and maintenance more convenient and efficient.

 

The CAN bus instrument seamlessly connects with the engine； key electrical components are arranged in the driver's cab， the same as international知名品牌.

 

Cab and Control System

 

A full-view driver's cab with spacious interior and wide field of vision.

 

A brand-new digital combined instrument with fault diagnosis and alarm functions， with the control lever within easy reach， providing comfortable and convenient operation of the entire machine.

 

Frame

 

The hinge joints of the frame are equipped with ball bearings to ensure the reliability of the connection between the front and rear frames.

 

The rear axle has a large swing angle, which effectively avoids the phenomenon of wheel suspension on uneven road surfaces.

 

An additional fuel tank guard plate is added to prevent the fuel tank from deforming under harsh working conditions; the fuel tank is placed at the rear, significantly enhancing the stability, overturning load capacity, and digging force of the entire machine.

 

Continuing the structural characteristics of XCMG products, the rear frame still adopts a reliable single beam frame structure. Through finite element analysis, the structural strength is improved, stress concentration is reduced, and local weaknesses are eliminated, making the entire machine safer and more reliable.

 

Working device and bucket

 

The working device has been optimally designed, adopting a Z-type reversed six-link structure with a single rocker arm, short pull rod, and horizontal moving arm cylinder. It has superior working performance and efficiency.

 

The bucket type design is reasonable, with low insertion resistance, high full bucket coefficient, and features a high-position discharge leveling indicator and a transport position stop block function, which can reduce the spillage of materials during operation.

 

The crossbeam of the arm is of a rectangular tube structure, which can effectively avoid stress concentration, welding defects, etc., and improve the structural strength.

 

Various pin shafts are made of special materials with special heat treatment processes, featuring high strength, good wear resistance, and long service life.

 

Brake system

 

The vehicle is equipped with both driving and parking brakes. The driving brake adopts an air-driven oil cylinder disc brake for four wheels, which has the advantages of smooth braking, safety and reliability, simple structure, and convenient maintenance. The dust-proof large-flow respirator is applied to the booster pump, facilitating maintenance and upkeep and improving the cleanliness of the internal components of the booster pump and other parts.

 

Repairability and maintainability

 

The engine hood adopts a large side door and an up-folding frame structure design. The side door opening angle is large, and the rear cover can be opened. Maintenance and upkeep of the engine and radiator are easy and convenient.

 

All maintenance points such as oil level checks, oil addition, and grease injection are arranged at easily accessible locations. The inspection and replacement of air filters, electrical equipment, etc., can be carried out conveniently; the warm air heater is placed on the right side of the driver's cabin, making maintenance and upkeep more convenient.
