Hydraulic Puller Transmission Line Stringing Equipment Cummins Engine

TY90 Hydraulic Puller

Hydraulic pullers are used to remove shaft-fitted parts (bearings or couplings). Pullers use a controlled hydraulic force in an effective way and can quickly separate (especially compared to the manual alternative) the parts.This hydraulic puller allows for the tension stringing of twin-bundle conductor of 500mm2 and below in mountainous and hilly areas, of twin-bundle conductor of 630mm2 and below in flat lands, and of single conductor 720mm2 in various terrains; besides, it can be used for traction stringing of OPGW or ADSS optical cable and 220kV haulage rope in various terrains.

Hydraulic Transmission

Closed hydraulic circuit for step less speed variation in both rotating directions.

This machine is provided with a pull pro-setting system that maintains the pre-set pulling value (also when the speed is reduced to "0") by automatically adjusting the operation speed according to the friction and unexpected loads which may occur.

Configuration

Hydraulic dynamometer with set-point and automatic control of maximum pull

Grounding connection point

Hydraulic front stabilizer

On board reel winder with automatic level wind, suitable for standard reel mod. 1100 and 1400

Hydraulic oil cooling system

Control instruments for hydraulic system and diesel engine
