Basic Equipment of the Service Pit

ELECTRICALLY CONTROLLED ROLLER SHUTTER

The roller shutter ensures prevention against fall of people to the service pit and enables
to drive the vehicle over the service pit by its all length and width.

It is delivered including an extension for a roller shutter, drive mechanism, stainless rails, zinc-coated sleepers and covering of roller shutter drive mechanism. The roller shutter is a travelling retractable roller shutter that consists of jackets, pins and rollers.

It is used for covering of the service hole after the end of service works. Inside the extension there is placed a driving mechanism that drives the roller shutter. The system is adjusted as follows: when opening the roller shutter the fresh air supply to the service pit is automatically switched on and thus the possible exhaust pollutants are vented out of the internal areas.

The load of the roller shutter is statistically calculated for load of 3 t per one wheel so it is possible to drive over the closed service pit by the truck tractor with the maximal speed of 5 km per an hour.

Additional equipment of the service pit for extra costs

BRAKE EXTENSION FOR A BRAKE BENCH

The brake extension is designated for storage of technical equipment of brake bench adjustment; it is produced from steel plates and sections. The brake bench is designated for measurement of:

• Left / right brake force
• Left / right rolling-resistance force
• Ovality level
• Front and rear brake efficiency
• Total brake efficiency of the vehicle
• Parking brake efficiency

AXIAL EXTENSION FOR CLEARANCE DETECTOR

The axial extension is designated for storage of technological equipment for geometry alignment of wheels. The axial extension of the service pit is produced from steel plates and sections. Inputs for electrical installation and drainage of liquids are made in the axial extension of the service pit.

Individual stages of construction readiness

PLACING THE SERVICE PIT ON THE BASE PLATE AND SCHEME OF CONCRETE WORKS

1st stage –excavation pit realization
2nd stage – base plate preparation
3rd stage – placing the service pit on the base plate
4th stage – connecting of the service pit with the service floor
