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
Model: sloping cam plate bi-directional plunger pump (German Rexroth)
Model: two-grade planet gear reduction (German Rexroth made by Beijing sole investment plant)
Type: 310 L2
Reduction ratio: 21.8
Brake response pressure: 2.5Mpa
Auxiliary oilway hydraulic system
Open type constant displacement throttle speed governing hydraulic system is supplied oil by gear pump and controls oil liquor’s cooling and hoisting tail bracket’s lifting of the whole hydraulic system through hand operated direction valve and ball valve.

Duplex gear pump: 1PF2G2-4X/016+014RR20MRL
Fan motor: GM5-12-1FE13-S-20
Hoisting motor: J2K-305
Sleeve extension oil cylinder: 3TG110×250
Model: inclined-axis bi-directional constant displacement tapered plunger motor (German Rexroth)
Safe operation rules
Only those who are familiar with safe operation rules and maintenance requirements of the type puller and receive professional training are allowed to operate the puller.
1. Both operators of tensioner and puller shall communicate each other to avoid that puller begins to work under operating condition of tensioner not tension laying and cause serious accident.
2. When puller works, it is prohibited that operators give up operating or leave puller.
3. When operating puller, you shall control handle and adjust pressure smoothly and steadily and avoid over-violent and quick force and brutal operation.
4. Absolutely avoid using backing the machine to brake.
5. After starting puller, check the meter whether it operates normally; stop to check if abnormal.
6. When the puller works, continuously observe each pointer; water temperature of engine shall be not more than 95℃; Hydraulic oil temperature shall be not more than 85℃; Tail bracket hoisting pressure shall be not more than 12Mpa; Brake pressure shall be not less than 3.5Mpa and not more than 6Mpa. Otherwise, the machine shall be stopped immediately for check.
7. Pressure of each safety valve shall be preset, avoid random adjustment by all means! If accidents, for example, puller fails to work, are caused arising from adjusting valve without permission, it will bring you much trouble and loss.
8. When puller operates, rotary speed of engine keeps above 1800r/min to maintain higher power and prevent overheating of hydraulic oil.
9. Under operating condition of driving, to change driving direction of puller shall be carried out after pulling wheels stop completely.
10. When puller operates, prohibit filling oil and repairing; when needing repairing, make engine flame out, in addition to reliable brake.
