Transmission Line Stringing Equipment Hydraulic Puller Cummins
Engine 9 Groove Number | TY150 Stringing Equipment Hydraulic Puller | - In tension stringing construction, puller is one indispensable tool
of main tools and its performance has direct impact on quality and
progress of stringing construction.
- Important components of the puller, with reasonable design and high
safety coefficient, are selected from international famous
professional manufacturers such as German Rexroth, German ,
American Eton, Italian ATOS; other parts and auxiliary equipment
are also selected from domestic excellent products, in addition to
strict production management by this company, thereby it
effectively guarantees fine performance and reliable quality of the
product and wins the flavors of numerous customers.
