| Sleeve extension oil cylinder | 3TG110×250 | |
| Radiator | B5024 | |
| Characteristics | The puller adopts installation mode of two-wheel single spindle trailer to be convenient for trans-field transportation. Pulling wheel, engine, hydraulic oil tank and operation board are reasonably arranged on both sides of main girder to make complete machine realize single-point hoisting and convenient hoisting transportation and reduce length of complete machine. The strength safety coefficient of anchor point is big, safe and reliable. |
| The pulling wheel can rotate in positive and negative directions, pull pulling rope and deliver pulling rope, and the pulling force can be preset and displayed visually from pressure gauge. | |
| Adopt German Rexroth planetary speed reducer with compact structure and reliable quality. |
