Dredger HCC 4000/71-GR
Productivity оf the pulp: 4000-5000 m3/h.
Productivity оf the soil (hydraulic deposition of soil category 1-2): 400-800 m3/hour; from 5000 m3 for the shift(8 hours).
Dimensions in working position: maximum length 24 m, maximum width 6.5 m, maximum height 5.3 m, board height 2.5 m, draft 0.8 m . Weight: 65 t.
The hydraulic dredger is equipped with an arrow. Suction pipe length is 9 m with hydraulic washing-out (jet), with pump capacity 300 kW, the water supply is 400 m3 per hour with hydraulic drop of 120 m.
Power unit main: CAT (capacity of 900 kW, 1900 rev /min, fuel consumption - 120 l/h).
Power unit: CAT (capacity of 350 kW, 1800 rev /min, fuel consumption - 45 l/h)
Fuel tanks capacity 12500 l.
The generator's own needs 250 kW.
Pump: 18'/16'-830-PET (made by VVV-SPETSTEKHNIKA). Pump specifications: 18 inch/16 inch, soil outlet from15% per hour, hydraulic drop of water column– 60 m, maximum capacity – 700 kW, rotation frequency – 700 rev./min. Hydraulic drive.
Technical characteristics of the pump (are provided geodetic lift is not more than 30 m for soil 1-2 category):
1. output up to 25% at the distance of transportation of pulp to 700 m (capacity 800 m3 of soil)
2. output up to 20% at the distance of transportation of pulp to 1000 m (capacity 700 m3 of soil)
3. output up to 15% at the distance of transportation of pulp to 1300 m (capacity 600 m3 of soil)
4. output up to 10% at the distance of transportation of pulp to 2000 m (capacity 400 m3 of soil)
Dredger this modification lifts the soil with water depth 1 - 7 m, pushing through slurry pipeline 2000 m geodesic a slope of not more than 30 m.
Control Room is equipped with:
- gauges (gauge, ammeter, frequency meter, pressure gauge (on the soil pump discharge nozzle, on the nozzle to wash the seal on the pipe hydrowashout));
- remote control of dredger movement;
- emergency shutdown system for dredger's network;
- observation devices for main engine.
For lighting on the dredger used two-wire isolated power distribution system voltage of 220V, 50 Hz.
For mains used a three-phase isolated power distribution system 380V, 50Hz.
For networks of control and signaling, as well as emergency lighting used two-wire isolated power distribution system voltage 24V DC.
Energy supply: self-contained.
The movement of hydraulic dredger is performed with the help of 4 winches with the capacity of 4.5 kW. Ladder winch - 7.5 kW, tracing force 7.5 t.
Pipeline diameter 550-630 mm
The enterprise guarantees the operation of the equipment for 1 year or 1800 Moto hours.
Maximum term of manufacturing is 8 months.
Power of main engine may vary, depending on the distance of transportation of the pulp and requirements for operation.
For the selection of a more suitable dredger to your requirements, please fill in the questionnaire, because depth of development and attachments of the dredger may vary slightly.
