The BK2 LB288 series is a hydraulically driven solution tailored for harsh off-highway environments. It highly integrates a low-speed, high-torque hydraulic motor with a normally closed multi-disc wet brake into a compact assembly. "BK2" typically refers to its brake series, while "LB288" indicates its nominal displacement of 288 cm³/rev class. This design is specifically intended to address the safety parking and service braking needs of off-road vehicles and construction machinery on ramps and rough road conditions. It provides reliable parking, emergency braking, and failure protection functions, and is a key component for enhancing the overall vehicle safety and maneuverability.

1. Highly Integrated Safety Design
◦ Integrated Structure: Integrates driving and braking functions into a compact unit, simplifying the vehicle axle design, saving space, and improving system reliability.
◦ Fail-Safe Mode: The normally closed design means that in the event of a hydraulic system failure (such as pipeline rupture or pressure loss), the brake will automatically and immediately apply braking to prevent the vehicle from rolling, providing extremely high safety.
◦ Smooth and Controllable: The braking process is controlled by hydraulic pressure, enabling smooth engagement and release of the brake to reduce impact.

2. High-Performance Multi-Disc Wet Brake
◦ Excellent Heat Dissipation and Durability: The brake discs work in oil, and the heat generated by friction can be quickly dissipated by the oil, avoiding the thermal fading phenomenon of dry brakes. It is suitable for frequent braking and long downhill conditions with an extremely long service life.
◦ Strong Braking Capacity: The multi-disc structure provides a larger friction area, which can generate braking torque far exceeding the driving torque in a small size, ensuring the vehicle can safely park under various loads.
◦ Maintenance-Free Operation: The sealed wet environment protects the friction discs, requiring basically no adjustment, and the maintenance needs are much lower than those of drum or dry disc brakes.

3. Enhanced for Severe Working Conditions of Off-Road Vehicles
◦ All-Environment Sealing: Special shaft seal and housing seal designs ensure that the motor and brake can resist the intrusion of mud, sand, dust, and water commonly found in off-road environments.
◦ Vibration and Impact Resistance: The overall structure and bearing system are reinforced against continuous vibration and operational impact on off-highway roads.
◦ High Power Density: While integrating the brake, it can still provide the strong driving force required by the vehicle.

This integrated brake motor is an ideal choice for the traveling drive systems of the following vehicles:
• Small and medium-sized articulated dump trucks: providing drive and braking for the rear axle or all axles.
• Telescopic handlers: used for traveling drive and safety braking of the front or rear axles.
• Off-road cranes and heavy-duty forklifts: used for driving and parking braking of the chassis traveling mechanism.
• Mining and tunnel-specific equipment: such as drive units for small underground personnel carriers and material transfer vehicles.
• Special agricultural and forestry machinery: such as large sprayers, skidders and other vehicles operating on sloped terrain.
