Currently, the most popular type of special equipment is backhoe loaders. Their popularity is due to the fact that they are able to accomplish much more various works than any other equipment, since there is a front bucket and rear excavator equipment. Moreover, compared with the same excavators and front loaders, this type has excellent maneuverability and compactness, which allows you to do any work in conditions with a small working space.
Description and features
Almost every brand has such machines in its lineup. One of the very first manufacturers to start mass production Backhoe loaders are the American Caterpillar, the first machine of which was introduced in 1985. From then until our time, technology has been improved many times. Thus, the modern Caterpillar 428 has a hydromechanical transmission, a powerful power plant, a reliable hydraulic system with closed center and additional hydraulic adjustment functions. Was designed this model based on the tractor of the same name. The Cat 428 itself served as the basis for many other similar machines. Thanks to its versatility, optional multi-purpose attachments, great mobility and all-wheel drive, this backhoe loader is ideal for a wide range of different tasks.
The Caterpillar 428 came out quite quickly. Its maximum speed, developed when moving independently, reaches 40 kilometers per hour, which allows the vehicle to reach not too distant objects in a very short period of time. However, its transportation over long distances is carried out using a special trawl.
As described above, this model uses an all-wheel drive system. This arrangement is found in almost all modern cars produced by this manufacturer. But the main difference of this model was advanced system, allowing you to control the smoothness of the ride. This was used to prevent the machine from rocking and to compensate for shocks that occur during loading operations or when moving over rough terrain. Brake system technology is of high quality and reliable brake mechanisms installed on all wheels, which provides high efficiency when braking.
The Cat 428 hydraulic system includes hydraulic distributors responsible for regulating flows hydraulic oil. Thanks to this, an optimal ratio of work to applied load was achieved. The design of the backhoe loader has been modernized, which made it possible to increase the initial moment in the process of breaking off the bucket by 10 percent.
The excavator cabin has increased level comfort and safety. The basic equipment is equipped with air conditioning and a well-thought-out ventilation system, thanks to which the operator can work in fairly favorable conditions, regardless of the factors environment. Only high-quality finishing materials are used, as well as sound-proofing and vibration-absorbing materials, due to which it was possible to significantly reduce the level of extraneous noise and vibrations that occur both during movement and during the work process. The operator's station offers excellent all-round visibility, and all controls attachments are located as ergonomically as possible, which provides additional convenience when using this equipment. It is worth noting that the control levers have received an improved shape, resulting in less effort required by the operator. Key Feature The Caterpillar 428 backhoe loader is modern system Accu Grade, thanks to which the operator can control the angle of inclination and depth of the ditches and trenches being dug, as well as additional attachments.
IN basic configuration The equipment is equipped with a bucket with a backhoe, a multi-purpose hydraulic loading bucket and a telescopic boom with the possibility of extending the handle. Optionally, the following attachments can be installed on the machine:
- Vibrating plate designed for compacting loose soils.
- Hydraulic breaker used in dismantling works, as well as for loosening solid masses of soil and rock.
- Auger drilling units designed for drilling wells of various depths and diameters.
- Leveling equipment designed for laying asphalt or concrete pavements.
Another important advantage of this model is its ease of use. maintenance and repairs. The hood of the car is quite large, thanks to which the maintenance personnel have full access to all the most important elements and nodes power unit. It is also necessary to highlight high angle rotating base, the ability to move with a crab move, the “track to track” mode (in which all wheels turn in different sides). All this provides the equipment with excellent maneuverability, which in turn allows you to perform any work in rather cramped conditions. This is precisely what determines the model’s leading position in the global market for special equipment.
Other features of this machine are the following:
- The boom has a curved shape, due to which the reach area during loading and unloading operations has been significantly increased compared to other models.
- The technique has cross-country ability, which allows you to move on loose soils, viscous and slippery surfaces and over rough terrain, as well as work in places that are difficult for other equipment to pass. This is due to the connected all-wheel drive and an effective braking system.
- There is a modern satellite system Product Link, which allows you to track both the movement of equipment and its current location.
But besides the advantages, Cat 428 also has some disadvantages, namely these:
- In the basic configuration, there is no possibility of turning the rear wheels, so the car turns only with the front ones. But this drawback can be compensated for by the additional installation of an all-wheel steering control system.
- The installed engine is quite demanding in terms of fuel quality. diesel fuel. Due to low-quality fuel, its operation is uneven. This is usually corrected by installing additional fuel filters.
- The ground clearance under the frame is not high enough, which is why various damage may occur when overcoming any obstacles.
- Wheel mudguards are not designed to last for a long time.
But despite this, this model has quite a lot positive feedback owners. As they say, even after the release of a significantly improved modification, the Caterpillar 428 is in very high demand, both among new special equipment and used ones.
Purpose
The Caterpillar 428 backhoe loader is used in construction, industrial sectors, utilities, and in road repair work.
