LG933L

Product Introduction

The LG933L is a highly versatile wheel loader designed to handle bulk materials efficiently. Its compact base and impressive cost-performance ratio make it an excellent choice for a wide range of applications, including harbors, construction sites, aggregate plants, and timber yards. This machine is renowned for its large breakout force, small turning radius, and high operating efficiency, providing exceptional flexibility and performance in various working environments.

The LG933L is equipped with a Yuchai turbocharged engine that meets the China II emission standards. This engine is known for its strong power output and high reliability, ensuring consistent performance even under demanding conditions. For added flexibility, the loader can also be equipped with a Weichai DEUTZ engine, which offers similar benefits in terms of power and reliability.

The cooling system of the LG933L features an enlarged radiator and optimized air channels for both the engine and hydraulic system. This advanced design effectively reduces the temperature of the engine water and hydraulic oil, resulting in high cooling efficiency. By maintaining optimal operating temperatures, the cooling system enhances the machine’s overall performance and longevity.

The wheel loader uses an axis-fixed power shift transmission case coupled with a single-turbine three-element hydraulic torque converter. This combination provides a compact structure and high reliability, making the loader easy to maintain. Additionally, the SDLG reinforced drive axle offers increased bearing capacity and enhanced durability, contributing to the machine’s robust performance.

The LG933L incorporates a load-sensing full hydraulic steering system, which ensures light and responsive steering while also providing energy-saving properties. The mechanically-operated hydraulic system for the working device is highly reliable and easy to operate, featuring hydraulic components from well-known brands that ensure high performance and dependability.

The loader’s new steel structure cab is designed to provide a wide field of vision and a larger operational space. It also offers good sealing performance to protect the operator from external elements. An optional air conditioning system can be installed to enhance comfort, making the cab a pleasant environment for extended periods of operation.

The electrical system of the LG933L utilizes high-end components from SDLG, ensuring stability and reliability. The machine features front and rear reinforced frames that have undergone 200,000 fatigue enhancement tests. This rigorous testing guarantees strong bearing capacity, balanced load distribution, and excellent overall stability.

The bucket of the LG933L is equipped with a protruding cutting board and a thickened bottom antifriction plate. This design reduces cutting resistance, increases the coefficient of fullness, and ensures high efficiency and reliability during operation. The enhanced bucket design contributes to the loader’s overall performance, making it a dependable choice for various material handling tasks.
