Steering drive axle LTG27F

The LTG27F steering drive axle is designed for telescopic forks with a lifting capacity of 3-3.5 tons.This is a high-performance axle that integrates vehicle control, steering, and braking.The biggest innovation of this product is the built-in two-speed gearbox, which can work in conjunction with an engine or hydraulic motor, providing the vehicle with excellent controllability in micro-motion mode and maneuverability off-road.The general modular design allows flexible adjustment of the connection size according to the requirements of equipment manufacturers, ensuring rapid matching and adaptation to the load of telescopic forks of various brands and platforms.Whether precise alignment is required in narrow warehouse spaces or heavy-duty driving on muddy roads at construction sites, the steering drive axle for telescopic forklifts can provide stable and reliable power and maneuverability.

Product features:

An integrated two-speed gearbox, and road grip efficiency is the benchmark:

The drive axle of traditional forklift vehicles usually has only one gear ratio, making it difficult to balance low-speed creep and high-speed transitions. The LTG27 breakthrough steering drive axle is equipped with a two-speed gearbox integrated into the axle housing, allowing the engine or hydraulic motor to be directly connected to the gearbox input interface. The drive mechanism of the electric motor/hydraulic motor enables the wheels to achieve precise and controllable low-speed creep characteristics, fully solving the problem that traditional mechanical transmissions struggle to control fork load under micro-operation conditions. The two-speed gear ratio switching ensures high-speed no-load operation and high-speed heavy-load operation, achieving an ideal balance between efficiency and power. The low-speed gear provides a large gear ratio, allowing the vehicle to move smoothly through narrow areas or complex terrain, significantly easing the operator's alignment work; the high-speed gear meets the speed requirements for shifting and improves operational efficiency.

The built-in wet brakes for travel and parking ensure a high level of safety:

thanks to the built-in wet brakes for travel and parking, a large braking torque and fast response are achieved, which significantly shortens the emergency braking distance. The brake has a normally closed design, and hydraulic pressure overcomes the spring force during travel to release the brake; after parking or engine shutdown, the spring automatically compresses the friction plate to ensure reliable parking and eliminate the risk of slope slippage. The wet structure fully covers the brake components with oil, protecting them from erosion by dust and dirt, ensuring long-term stable brake performance, low wear of friction plates, and extended maintenance intervals.

The centrally mounted double-acting steering cylinder provides flexible and precise control:

The centrally mounted double-acting steering cylinder provides high torque at the steering wheel and sensitive response, and thanks to the steering knuckles with a large steering angle, the drive axle with a two-speed gearbox can achieve a much larger steering angle than conventional axles, effectively reducing the turning radius of the entire machine. When operating in narrow warehouses, construction intersections, or forested areas, the mobility and passability of the vehicle are significantly improved. At the same time, it is equipped with a medium-speed sensor, which reduces the driver's workload.

Limited-slip differential that does not slip on rough roads:

Built-in limited-slip differential that can automatically detect the speed difference between the left and right wheels. When one wheel starts to slip on muddy, icy, snowy, or gravel-covered roads, the differential automatically locks, ensuring smooth vehicle start-off. With this configuration, the LTG27 steering axle also provides excellent traction on unpaved roads such as construction sites, farmland, and mining areas.

High-quality alloy steel gears with high torque:

The main transmission gears and planetary wheel gears are made of high-quality alloy steel materials, which undergo carburizing and quenching, resulting in high tooth surface hardness and good core toughness. Through optimized gear modification, the contact stress is evenly distributed, allowing it to withstand stronger instantaneous impacts and prolonged heavy loads, enabling the telescopic forklift to operate more smoothly when climbing ramps, ascending hills with heavy loads, and overcoming obstacles, further enhancing the forklift's off-road capabilities.

Modular design, suitable for various assemblies:

The LTG27 steering drive axle features a modular design that allows for quick adjustment of installation size and shape. Equipment manufacturers only need to provide the connection parameters of the entire equipment, and we can develop an adaptation plan within one to two weeks, significantly shortening the development cycle for new models.

Main technical parameters:

• Rated load capacity: 3-3.5 tons

• Transmission gears: two gears (low-speed micro-motion gear + high-speed transition gear)

• Braking type: built-in wet normally closed brake for travel and parking

• Steering form: centrally mounted two-way hydraulic drive, large-angle design

• Differential configuration: limited-slip and non-slip differential

• Suitable power: engine or hydraulic motor (interface can be customized)

Application scenarios and technology selection

The LTG27 steering drive axle is mainly used for telescopic forklift loading (3-3.5 tons), agricultural loading and unloading, and other wheeled machinery requiring precise low-speed control and good off-road performance.

When selecting a model, the customer must specify: the maximum load of the entire machine, maximum travel speed, maximum gradeability, drive method (electric motor or hydraulic motor), interface dimensions between the motor and axles, and rated parameters. Our technical team can assist in calculating the required speed ratio, braking torque, and steering wheel angle, and recommend the most suitable special axle configuration for telescopic forklift loading.

The steering drive axle for telescopic forklifts can be used in the following configurations with various options:

Loading and unloading operations on construction sites: when driving under heavy conditions and frequently maneuvering in tight spaces, the two-speed gearbox provides low rotational speed, and with large steering angle, it easily handles stacking and unloading operations.

Agricultural production and storage: muddy warehouses or field roads, anti-slip differentials and wet brakes prevent dirt ingress and failure.

Municipal rescue and emergency services: to ensure safe parking on ramps, quick transitions and precise stops are required, with smooth shifting between high and low gears, as well as normal braking.

Mines and quarries: high-quality alloy steel gears and reinforced bearings provide long-lasting protection when operating under heavy conditions, on rough terrain, and in dusty environments.

Production and quality control

The drive axle with a two-speed gearbox is assembled on a specialized production line. Key processes include dynamic measurement of bearing preload, detection of gear tooth contact patterns, and leak testing of wet brakes. All finished products undergo testing on a load bench, covering indicators such as transmission efficiency, noise level, temperature rise, braking efficiency, and shift smoothness, and can be shipped after passing the tests. The company is certified under the ISO9001 quality management system, and its main testing equipment includes precision instruments such as coordinate measuring machines, a spectrum analyzer, a metallographic analyzer, and an ultrasonic flaw detector, ensuring reliable accuracy and stable quality for each LTG27 steering drive axle.

Professional technical services

The company has a technical support team for construction machinery drive axles, which can assist customers in selection calculations, interface coordination, and vehicle driveline simulation for the LTG27 steering drive axle. For original equipment manufacturers receiving support, it can provide assistance in conducting bench tests of axle samples and real vehicle load tests. When shipping, the axle comes with installation instructions, seals, and a list of wear parts, making it easier for customers to perform on-site assembly and subsequent maintenance. Whether it is a three-ton or four-ton telescopic forklift, we can offer the most suitable drive axle solution.
