BASIC EQUIPMENT FOR TRACK CIRCUITS - Press PP 50 / PP 100

Attachments consists of a solid packing in the form of a "C", the two rods, a sleeve and two nuts. The special shape of the nozzle allows for fast and reliable operation of the recess and insert track pins and bushings in all operating conditions, even with established shoes. It can be used to force the recess 50 tons. The approximate weight of 44 kg.

Depending on the type of work on the track chain and the machine model, the equipment must be used with specific additional equipment, i.e. bushings, spacers, pushers, etc. Their choice should be made depending on the type of the tracks.

The diagrams Ris.8.i Fig.9 considered the location of equipment for excavation finger of track chain: in red highlighted additional equipment for the appropriate circuit. In a similar manner as is done with the help of additional equipment insertion and removal of plugs.

Figures 10 and 11 demonstrate the installation and removal of suspended wheels track chain with the help of additional equipment, highlighted in red.

Pumps and cylinders.

Pumps

Designation RM 2 and PE 1 is identified without flexible pipes and quick action clamps as shown in The following specific photo. Pipelines and clips are available separately on request.

Used as an alternative pump PM 2; in this case the hydraulic press with these pumps are designated 50 and the PPE PPE 100. The two-step process, with automatic transition from the first stage to the second stage. Includes 4-way hand-lever valve with 3 position with a pressure gauge, an internal safety valve, set during installation to the maximum working pressure indicator and the valve on the outside of all intermediate pressure, depending on the job requirements.

Ability to work in continuous cycle with pressure up to 500 bar in intermittent cycle for 6 minutes before the maximum working pressure. The ability to start the engine in a closed hydraulic circuit under pressure. The maximum pressure of 700 bar oil flow 0.85 dm3 per minute.

Fuel tank capacity of 16 dm3.

Engine power 1.1 kW.

The approximate weight of 45 kg without oil.
