描述:
PK-55 is a modern productive machine. It is designed for excavation work, loading soil, rocks, coal, sand, crushed stone, etc. In addition, he can independently fill earth embankments and shafts, work in a bulldozer mode, perform site planning, and dig shallow pits.
概观:
  • Vehicle type: Loader
  • Operator Protection: ROPS-FOPS
  • Bulldozer equipment: rock bucket (bucket volume 2.7 cubic meters)
  • Cabin design: Modern
  • Carrying capacity: 5.5 tons.

In 2013, for the 80th anniversary of ChTZ, Chelyabinsk tractor builders assembled a new PK-55 loader, adding to the line of produced wheeled models.

The loader is based on the serial PK-46. The new machine more fully meets the demand of consumers for more powerful equipment at a reasonable price. This allows you to effectively compete with forklifts from Chinese companies.

The main difference between PK-55 and its predecessor, PK-46, is the carrying capacity of 5.5 tons instead of 4.6.

This is achieved by means of a bucket of increased volume. The 55th loader bucket holds 2.7 cubic meters, not 2.4 cubic meters. Accordingly, its width is more than 2870 mm instead of 2650.

At the same time, the bucket itself turned out to be lighter, despite the fact that it is larger. The developers of the machine from the Design Center for Road Construction Machines (KC DSM) changed the design of the bucket: they removed the massive central support, reinforcing the side ones (a similar bucket was successfully tested on the PK-65, a vehicle of a heavier class).

The testers evaluate the ability of the new loader to demonstrate increased lifting capacity using a special method: on a fully extended boom, it can withstand a load of 11 tons without taking off the rear wheels.

To ensure stability at the rear, a counterweight was installed on the new loader, which was twice as heavy: it was 360 kilograms, it became 750. In fact, it is the same as on a heavier wheel unit from the factory PK-65 family. Only two holes for the hooks were added, using which the machine is lifted by a crane.

To ensure the increased carrying capacity of the new front-end loader, the pressure in the hydraulic system has been raised by 10 percent to 200-210 atmospheres. For this, the hydraulic valve of the Italian company Gidrokontrol was reconfigured.

The weight of the car has increased by only 300 kilograms. The strength characteristics of the boom are sufficient to withstand the planned weight and dynamic loads.

The loaders use reliable pneumatic wheels specially designed for this type of equipment, providing sufficient traction for efficient work. The tires on PK-55 are the same in size as on the base model, but since the load on the front axle has increased, their standard layer thickness has been increased by 20 layers instead of 16. Because of this, they became stiffer, which made it possible to provide a discharge height of three meters.

There are also differences: on PK-46, for access to the radiator, its entire lining, the so-called headband, rises, and on PK-55 it is made stationary. Radiator access is now more convenient. The grille opens like a door. The same design is planned to be implemented across the entire range of loaders.

The installation of axles on the PK55 Loader with an increased gear ratio led to a decrease in the maximum speed, and therefore the designers agreed with the German company ZF a special modification of the gearbox. In order to ensure high transport performance by changing the parameters of the torque converter.

Chelyabinsk tractor builders presented the new loader PK55 to consumers for the first time at the main industry exhibition of the country, Construction Equipment and Technologies 2013, taking place in Moscow.
