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.
