150kN Hydraulic Cable Puller With Cummins Engine With Sloping Cam
Plate Bi-directional Plunger Pump
Drive system Closed type circuit hydraulic drive system adjusts speed through
hydraulic plunger pump with bi-directional variable displacement,
reduces speed through planet gear and drives pulling wheels to
rotate in positive and negative directions through the first level
gear terminal drive. Cooling mode: forced cooling | Performance parameter Max intermittent pulling force: 150kN Max continuous pulling force: 120 kN Corresponding speed: 2.5 km/h Max continuous tractive speed: 5 km/h Corresponding pulling force: 60 kN Pulling wheel diameter: 600mm Groove number: 9 Max diameter of applicable pulling rope: 26mm Weight: 6600kg Overall dimension (length*width*height): 4800*2350*2470 mm Hoisting mode: single point |

Routine and Scheduled Maintenance
Check and maintenance before working every day
To guarantee reliable work of puller, be sure to check following
items before working, and eliminate off-normal phenomenon.
1. Whether fasteners in each connecting location get loose.
2. Whether cooling system of engine is filled up with water;
whether water pipe connector has water leak.
3. Whether oil sump of engine is enough filled with engine oil
according to engine oil scale label.
4. Whether fuel oil in the fuel tank is enough; whether each oil
pipe joint has oil leak.
5. Whether accumulator is live; whether starting circuit joints of
engine get loose; check lighting equipment.
6. Whether there is enough lubricating oil in speed reducer.
7. Whether hydraulic oil with code designation is enough in
hydraulic reservoir; whether each oil pipe joint has oil leak.
8. Check whether each control handle is put in middle position.
9. Check whether the engine is prepared.
Check and maintenance after working everyday
1. Check fuel oil reserves, if fuel oil is short, it shall be
filled.
2. Check whether oil pipe, water pipe and accessories are leaky
3. Check sealing and overheating of speed reducer, hydraulic oil
pump and motor.
4. Check coupling bolts and pin shafts of engine, speed reducer,
hydraulic oil pump, hydraulic motor, traction wheel, fan and pipe
joint whether they get loose.
5. Welding seam of oil tank and vehicle frame is normal.
6. Let cooling water out when air temperature is below 0℃ (without
filling anti freezing fluid)
7. Check tire pressure whether it’s enough, if the pressure is
short, it shall be filled. Filling pressure is 800Kpa.
