Model overview

The first PUM 500 cars began to be produced in 1992.

Since 2005, the PUM-500 has been replaced by a modified model PUM-500U .

the PUM-1000 and PUM-600 models were released , in which the control levers were replaced with joysticks, the cabins were improved, and a thermoelectric micro-climatic unit was used for the first time.

The line of mini loaders includes models PUM-800 and the largest standard size PUM-1250. In 2012, the plant began production of a new mini-loader PMK-6.02, created on the basis of PUM-500U.

Main technical characteristics of PUM-500

The technical characteristics of the loader are presented in the table:

Replacing the PUM 500 engine increased the power of the loader, reduced fuel consumption, and the machine began to comply with Euro II and EPA standards.

The HATZ 2M41 manufactured by HATZ Diesel (HATZ Motorenfabrik GmbH & CO.KG) is the world's first industrial diesel engine with built-in automatic protection.

Hatz multi series is a series of long-life multi-cylinder industrial diesel engines. Hatz multi series engines are used in construction, mining, road repair equipment, and in diesel generator sets.

Before making a decision to purchase a PUM, we recommend reading reviews from real owners of loading equipment on specialized farming forums or forums about special equipment.

Here, owners share useful information and their own experience, the necessary PUM 500 diagrams, and look for instructions on how to independently repair equipment.

Here is one such review (spelling and punctuation preserved):

1 engine is not bad, there are spare parts in stores. 2 fuel consumption is low. 3 starts well in cold weather 4 yes, it eats any diesel fuel. My choice was pum or mksm. mksm costs twice as much, but the prices for spare parts are the same.

Attachment Options

The PUM-500 Bobr loader can have a wide range of applications, thanks to 20 replaceable attachments. Each of them has a quick-release coupling that allows you to quickly connect to the machine pipelines.

The most popular of them:

Device

The front loader is designed quite simply. The wheelbase has a minimum length for greater stability and maneuverability, and the base itself has a low center of gravity.

The power unit is a diesel engine, which drives the loader itself. The hydraulic pump takes power directly from the diesel rotor.

The boom has only 4 hydraulic cylinders, two of which provide lifting and lowering, and the rest control the bucket itself directly. Loader diagram PUM 500

• A rotary snow blower is designed for removing snow from streets, sidewalks, and so on;
• Mounted forks allow this machine to perform the functions of forklifts and work with loads on pallets;
• The fork allows you to fix and transport various loads, such as bushes, pipes, branches and so on;
• A backhoe is used to dig trenches;
• A hydraulic drill is used for drilling wells up to 1 meter deep, which is mainly suitable for utility purposes;
• The hinged hook is also used for transporting loads weighing up to 500 kg;
• Concrete mixer for concrete mixture;
• The pumping unit can pump out water at a speed of 100 cubic meters/hour;
• The compression unit is used to work with various pneumatic equipment;
• Welding installation;
• Two-axle trailer. Has a load capacity of 750 kg.

It is also possible to use a variety of equipment for road construction work.

Control

These machines turn around not by turning the wheel normally, but by regulating the rotation speed. In essence, it is the same as that of tanks. If you need to turn right, just brake the right side, if you need to turn left, then vice versa. This ensures a minimum turning radius.

Control occurs from a closed cabin using levers.

Separately for movement and separately for controlling the boom, as well as any possible attachments. They use a common control for the bucket hydraulic system.

Engine design feature

Early versions of the Universal Small-Size Loader-500 were equipped with a D120-10 diesel engine, which was produced by the Vladimir Motor and Tractor Plant. It is characterized by the presence of two cylinders and air cooling. The main advantages of the loader are its high efficiency of 50% compared to gasoline analogues and its long service life, achieved using innovative technologies. The equipment is started by an electric starter.

Engine D120-10

The engine parameters of the loader are as follows:

• Cylinder volume – 2.08 l.
• Power – 22.1 kW.
• Rotation – 2000 rpm.
• Cylinder diameter – 105 mm.
• Dimensions: 689*628*865 mm.

More modern models of the loader have a German Hatz 2M41 engine. Its advantage is its ability to work in any weather conditions.

Hatz 2M41 parameters:

• Power – 23.7 kW.
• Rotation – 2000 rpm.

Loader Pum 500

The PUM-500 loader, simply called “Beaver”, is a universal small-sized special equipment used for loading and unloading materials and bulk solids. It is produced at Uralvagonzavod. It stands out among analogues due to its reasonable cost, high maintainability, availability of components and small dimensions.

Advantages of a compact loader

This loader model is very popular because it is universal. It can be found in various fields of production and industry. The loader is often chosen for the needs of utility companies, for performing work in the private sector, servicing small warehouses, construction sites and industrial facilities. Small-sized equipment has high cross-country ability and is therefore capable of performing work in hard-to-reach places. The main technical characteristics of the equipment are:

• maximum speed - 9 km/h;
• width - 130 cm;
• height with bucket - 190 cm;
• weight with bucket - 2760 kg;
• load capacity - 500 kg.

This model is equipped with a two-liter four-stroke air-cooled diesel engine. The motor produced by a German company is characterized by increased reliability and ease of use. Its motor life is capable of outlasting the main components and assemblies, which makes the equipment incredibly popular.

Optional attachment for more options

The small-sized loader PUM-500 has a very wide scope of application, since the manufacturer provides a large set of additional attachments that allow profiling of equipment for various jobs. If necessary, the following can be attached to the loader:

• fork;
• snow clearing rotor;
• sweeping brush;
• compressor;
• excavator equipment;
• water pump;
• hydraulic drill;
• steel ladle;
• concrete mixer.

Selection of tires for PUM-500

The conveyor loader is equipped with GK 9.00-15 (230×380) wheels of the OI-353 model. Compared to other larger tire models, they are significantly cheaper, making them extremely affordable. In addition to standard wheels, which have rather weak characteristics, other models can be installed on the loader, such as 10-6.5, 10.0/75-15.3 and 11.5/80-15.3.

In most cases, the tire tread depth for the PUM-500 loader is required to be small, since this type of special equipment is operated in fairly favorable conditions where there is no sharp rocky soil. Nevertheless, the market offers tire options with tread depth not only L2, but also L3. This allows you to choose the ones that are suitable for any operating conditions, even if the loader has to work on dismantling work with a high probability of puncture.

It should be noted that the weight of the loader with the bucket is only 2760 kg, which, together with the additional 500 kg of cargo, does not create such a large load on the tires as to lead to their rupture. However, the use of passenger car wheels on the forklift is not permitted.

When it comes to tread pattern type, manufacturers such as Titan, Michelin, Trelleborg, Armor and others offer a full range. The most popular tires are with herringbone tread. They provide good traction and are characterized by increased wear resistance. Such wheels perform well when performing excavation and construction work. If it is necessary to load bulk materials on flat surfaces, it is recommended to use straighter treads, such as diamond, hexagon and others. They perform well on dry and even surfaces, providing minimal wear.
