66KV Overhead Transmission Line Stringing Equipment  is composed of 4 ton puller or 3 Ton puller with tensioner, and accessory tools for single conductor or OPGW stringing.

We are the leading manufacture of stringing equipment and tools in China.All the pullers, tensioners and stringing blocks have been tested before ex-works, and got CE certificates.

1. SA-YQ40 Hydraulic Puller

Single sheave Stringing Block

Application: It is suitable to string stranded aluminum and ACSR conductors on tangent structures. Compression sleeves, swivel connectors, and pulling rope connectors can pass through the groove. The sheave is made in aluminum alloy or high strength nylon. The big size 508mm, 660mm aluminum alloy sheave can be lined with neoprene. The big size 660mm, 822mm, 916mm, 1040mm nylon sheave can be lined with neoprene.

Note:

1.       Hook fitting, round eye fitting, and clevis fitting are optional, please specify when ordering. Customized blocks could be supplied on request.

The data in the model means the outer diameter of sheave X width of sheave (mm).

2. All the sheaves are mounted on ball bearings. The frame of blocks is made in galvanized steel.

 Anti twisting braided steel wire rope

Anti twisting steel rope is specially braided from  high strength, high flexible galvanized steel wire. The braided steel strand has high flexibility, complete stability to rotation under tension force. The wire rope is lubricated for long time usage.

It can homogeneously distribute the pressure between the elementary wires. The special rope can increase efficiency during the overhead transmission line stringing work. The rope is packed in steel drum which can be installed directly on the reel winder of puller.

4. Aluminum alloy Conductor Come Along clamps

Application: It is specially used for adjustment of sagging of conductors, to hold the conductors temporarily during the stringing operation. The whole body and jaw is made of High strength Aluminum Alloy, light weight and good for protecting the surface of conductors.

Drum stands with disc brake

Application: It is used to raise and support reels in conductor stringing operations.

The reel could be controlled by side disc brake.

Features: It could be dismantled into 5 pieces, easy for transportation.

Drum Cradle (Pilot Wire Reel Cradle).

Application: It is used for paying out or taking back pilot steel wire rope on site by manpower.

It could hold the Pilot Wire Steel Reel of Max. Diameter 1200mm.
