Special automotive equipment is a reliable and loyal assistant to a person in solving many domestic and industrial issues. With its help, it is possible to carry out the transportation of goods, process agricultural fields, take part in public works. In this article, the PUM-500 loader will be considered, the technical characteristics of which will also be necessarily indicated.
general information
This car in the folk environment has received a rather funny, but at the same time simple nickname “Beaver”. Universal transport is designed and manufactured to increase the degree of mechanization of loading and unloading operations with materials having small-sized form I-IV categories, and with bulk materials.
PUM-500 (its technical characteristics are optimal taking into account its dimensions) is produced by a Russian company under the name Uralvagonzavod. Moreover, this model makes up about 90% of all loaders produced by the plant.
Fields of application
The PUM-500 loader is most often operated by:
- In logistic operations. This vehicle performs the loading / unloading of piece goods, as well as their transportation on the production site or warehouse.
- In the construction of residential and industrial facilities. PUM-500, the technical characteristics of which allow it to perform the functions assigned to it for a long period, is optimal for carrying out work on loading / unloading various soils (light clay, loam, sand).
- For the needs of the population. The compact dimensions of the loader allow it to cope with the tasks in a small space. Also with the help of "Beaver" you can engage in excavation work.
- In a communal environment. The machine is very effective for thoroughly cleaning park areas, roads, sidewalks from snow and dirt in a city. In addition, the loader provides an excellent opportunity to plan the terrain. Having low pressure on the ground and small dimensions of its own, the Beaver does not cause any serious damage to roads and topsoils.
Environmental conditions
PUM-500 can be used both in standard and in rather cramped conditions. Use of the car in a zone of a temperate climate is allowed. The loader works without problems in the temperature range from -30 to +40 degrees Celsius. The operator in the vehicle is provided with very comfortable conditions thanks to the thoughtful design features of the cab, equipped according to all the rules of ergonomics and biomechanics.

Attachments
The study of auxiliary components of the loader is, of course, also a very important technical characteristic of it. The PUM-500 rotary snow blower is designed for thorough cleaning of streets, sidewalks and other areas from snow.
In addition, if necessary, and depending on the situation with the machine, such units can be quickly and reliably paired:
- Bucket without teeth. It is used for loading sand, soil and other bulk materials.
- Bucket with teeth. It uses for the same operations as its "toothless" counterpart, but also for working with rocks and frozen soils.
- The brush is road. It is easy to guess that with its help sweep the streets.
- Mounted forks. With their help serve pallets and boxes.
- Forklift. It is used in the municipal sphere for the shipment of trees, branches, shrubs, pipes.
- Hydraulic drill. It is used for drilling wells up to one meter deep.
- Hinged hook. With it, there is an excellent opportunity to move goods weighing up to 500 kg.
- Concrete mixer. It allows you to quickly get 65 liters of finished concrete.
- Pumping unit. It has a capacity of up to 100 cubic meters per hour and is used during the repair of water pipes.
- Compressor. By connecting to it, you can use a pneumatic tool.
- Welding machine.
- Biaxial flatbed trailer. Its carrying capacity is 750 kg and its volume is one cubic meter.
Attachments are connected using special quick-release couplings to the hydraulic pipelines of the high pressure of the machine.
German engine model
PUM-500 (technical specifications, reviews are given in this article) since 2005 is produced with a HATZ 2M41 motor. This power plant has the following advantages:
- Air cooling available with axial fan.
- Lubrication is carried out under pressure in a closed circuit.
- Hydraulic pumps have an auxiliary drive from the crankshaft of the motor.
- At start up, smoke is reduced.
- A dry air filter is included.
The “U” index, that is, the PUM-500U loader, has been added to this machine in the designation. In addition, the named engine is the world's first diesel engine with integrated protection automation.
Positive traits
Why is PUM-500 good? Its technical characteristics made it possible to provide such advantages:
- A short payback period and an optimal ratio of quality and price.
- Great choice of attachments used.
- Compact size and small turning radius.
- Efficiency and profitability.
- High degree of noise isolation, comfortable and safety cabin.
- Optimum ergonomics for the driver.
- The presence of all-wheel drive and a sufficiently large clearance.
- Smooth running while riding and operating accessories.
- The center of gravity is low, and therefore the machine is very stable.
- Low maintenance costs and easy repair.
- A wide selection of spare parts and components.
Subtleties of work
How to use the PUM-500 loader? The instruction for its operation states that the machine must be operated by an experienced driver. At the same time, it is not allowed to overheat the motor and use non-adapted attachments. The cleanliness of the oil in the hydraulic systems of the loader must correspond to the specified class in the technical data sheet. It is required to regularly check the level of lubricating and cooling liquids, fuel. In addition, special attention is paid to electrical wiring and batteries. It is important that the insulation of the cables is reliable, the batteries have a full charge.
User Feedback
How much is PUM-500 in demand? Owner reviews are unambiguous in answering this question - consumers really like the car, which is also evidenced by the high levels of its sales. In particular, you can often hear from the owners of the truck that it has a very good, in their opinion, engine that consumes little fuel. In addition, the vehicle starts up without problems on cold winter days. The aggregate is unpretentious to the quality of diesel fuel. And most importantly, PUM-500 is almost twice cheaper than its competitors at the same price for spare parts. It is also important that in the event of a breakdown, in most cases the car can be repaired independently without resorting to the expensive services of specialists.
As for the direct control of the loader, in order to still ride on it without problems, certain skills and experience on the part of the driver are required.
