Use And Classification Of Loaders

Sep 05, 2019

The loader is a construction machine with high work efficiency. It is mainly used for shovel, loading, transporting, digging, etc. of loose piled materials. It can also be used for finishing, leveling and carrying out the work. After replacing the corresponding working device, it can also carry out excavation, lifting and Loading and unloading materials and other operations.

Applications

Widely used in urban construction, mining, railway, highway, hydropower, oil field, national defense and airport construction, etc., it is extremely important to accelerate the progress of the project, ensure the quality of the project, improve working conditions, improve work efficiency and reduce construction costs. effect.

Classified by walking system structure

(1) Tire loader: A loader composed of a tire-type chassis as a traveling mechanism and a working device and its operating system.

Advantages: flexible maneuverability, high work efficiency; low manufacturing cost, convenient use and maintenance; tires also have better buffering, vibration damping and other functions to improve the comfort of operation.

(2) Track-type loader: A loader consisting of a crawler-type special chassis or an industrial tractor as a traveling mechanism and a working device and its operating system.

Advantages: large traction, good off-road performance and stability, large climbing ability, small turning radius, and can work in harsh environment conditions.

Classified by engine position

(1) The front engine of the engine is placed in the loader in front of the operator.

(2) The rear engine of the engine is placed on the loader behind the operator.

At present, domestic large and medium-sized loaders generally adopt the structure of the rear of the engine. This is due to the rear of the engine, which not only can expand the driver's field of vision, but also the rear engine can also be used as a counterweight to reduce the overall equipment quality of the loader.

Classified by steering

(1) The deflecting wheel steering type uses the wheel of the wheeled chassis as a steering loader. It is divided into three types: yaw front wheel, yaw rear wheel and all wheel steering.

Disadvantages: The integral frame has poor maneuverability and is generally not used.

(2) The articulated steering type relies on the front wheel, the front frame and the working device of the wheeled chassis, and the loader that oscillates horizontally around the hinge pin of the front and rear frames.

Advantages: The turning radius is small, the maneuverability is flexible, and it can be operated in a small field, which is currently the most commonly used.

(3) Steering of the steering wheel on either side of the wheeled chassis or the driving wheel speed difference on both sides of the tracked chassis.

Advantages: The small size of the machine, maneuverability, can achieve in-situ steering, can work in a narrower space, is the steering mode adopted by micro-loaders in recent years.

Classified by drive

(1) The front wheel drive type uses the front wheel of the walking structure as the loader of the drive wheel.

(2) The rear wheel drive type uses the rear wheel of the walking structure as the loader of the drive wheel.

(3) The front and rear wheels of the all-wheel drive type walk structure are used as loaders for the drive wheels. Modern loaders are mostly all-wheel drive.
