China 2.5 ton Backhoe Loader 388H 4 Wheels Steering With 75KW engine
China 2.5 ton Backhoe Loader 388H 4 Wheels Steering With 75KW engine
The 388H backhoe loader is an upgrade based on the mature equipment and technical performance of existing products, including engine emission upgrade, structural lightweight upgrade, working device parameter upgrade, etc., which further improves the comfort, safety, maintainability, reliability, supportability and economy of the product.
Backhoe loaders have two main steering modes: two-wheel steering, and four-wheel steering (crab walk). The difference between them is:
Two-wheel steering (2WS).
- Steering: Front wheel only.
- Turning Radius: Larger turning radius.
- Maneuverability: Not as flexible as 4-wheel steering in narrow spaces.
- Application Scenario: Suitable for workplaces with large space, such as road construction, large site leveling, etc.
- Advantages: Simple structure, low cost, easy maintenance.
Four-wheel steering (4WS).
- Same direction steering: The front and rear wheels steer in the same direction. This mode reduces the turning radius and improves maneuverability in tight spaces.
- Reverse steering (also known as crab steering): front and rear wheels steering direction is opposite. This mode allows the machine to move sideways and is ideal for precise maneuvering in confined spaces, such as near walls or obstacles.
- Coordinated Steering: The steering angles of the front and rear wheels are coordinated as needed for optimal maneuverability and stability.
Advantages of four-wheel steering.
- Smaller turning radius: improves maneuverability in tight spaces.
- Reduced tire wear: Because tires slide less.
- Increased Productivity: Faster steering speeds and more precise control increase productivity.
- Safer maneuvering: Easier to control in tight spaces, reducing the risk of collision.

How to shipping backhoe loaders?
Backhoe loaders enjoy flexible and diverse options for international due to their relatively compact size. By container and by vessel are two common options, each offering unique advantages.
By container: Due to the small size of backhoe loaders, containerized shipping is a cost-effective option. Typically, a backhoe loader with its tires removed can easily fit into a 40HQ container. If you need to maximize the use of container space, two backhoe loaders can be loaded at the same time, simply by removing the extra bucket. The remaining space can be used to load spare parts for the machine, such as filters, belts, hydraulic oil tubes, etc., or other attachments needed for the job, such as hydraulic hammers, grabs, quick connectors, etc., according to customer demand, thus maximizing the efficiency of shipping. In addition, by container provides safer protection for the machine, reducing the risk of collision or natural environmental erosion during shipping.
By bulk vessel: By bulk vessel is another cost-effective method of transportation, especially for backhoe loaders. Utilizing the lifting equipment on board, the backhoe loader can be lifted and secured directly into the hold of the ship. If the customer chooses additional attachments, in order to avoid damage during shipping, we will pack these attachments in wooden crates and fix them together with the backhoe loader in the hold of the ship to ensure that the cargo arrives at the destination safely. By vessel usually has a lower unit price than container transportation, especially in the case of large volume shipments, where the cost advantage is even more obvious.
