Product Description

Application:

This machine is used to pull steel wire rope with max diameter of 38mm,to pull four bundle conductors with max sectional area of 720mm2 in giant span crossing over valley/hills/ great river etcflatland,to pull six bundle conductors with max sectional area of 720mm2 in flatland area. 

Technical Features:

Overload protection device for pull pre-setting which allows to maintain the pre-setting force even at “0”speed.

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

Its pull speed can be adjusted in both direction with infinitely variable speeds.

When change rope wheel on reel winder,the hrydralic clamp next to the bull wheels will brake and tight the rope,to ensure safety in the process.

The main stander is made by customized rectangular steel tubes which are formed by one take art,to avoid any deformation which cause the mechanical parts.

The bull wheel is made of special material and technology,neither rusting nor abrasion,to ensure a longevity of the the machine.  

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

Automatical Hydraulic oil cooling system.

Hydraulic front stabiliser.

Grounding connection point and temporay anchor point.

Configurations Features:

Commins Engine which are reliable and easy access service station all over the world,its power is about 10% higher than European products.

Main parts in hydralic system are from German Rexroth,such as pump\motor\speed reducer,other parts such as pull meter\winder motor\valves\switches are also come from famous international brand.
