Taking puller’s place
1. Haul puller into selected field to put; make incoming line groove of pulling wheel aim to rod tower center as much as possible; the deviation range is ±7°to reduce lateral load. The laying location and rod tower shall be 100m～150m apart, when deviating from this range, the pulling wheel and pulling wheel cover shall be worn out in the process of traction.
2. After determining the location of puller, start adjusting working location of puller (given as figure 1). Retract fore stabilizer completely; make back stabilizer be adjusted to suitable location and insert pin shaft. Here the puller is in working position.
3. Anchoring puller (given as figure 3). Center stressing direction of anchor bed shall align with stretch direction of anchor in order to make anchor bear pulling force and not bear lateral force. When anchoring, anchor block, steel wire rope loop, shackle, lever block or double hook with above 10-ton stress shall be used; directly pre-tension the anchor after jointing.
4. Two anchor points in the forepart of puller are to adjust the consistency of puller and wire tower direction. If the deviation of puller and wire tower is more than 10°, the double-end anchor in the forepart shall be adjusted to correct.
