As a efficient tool for assisting the helicopter to deal with the cable stringing tasks, the MARSHINE Helicopter Cable Stringing Block is a specialized aerial cable stringing pulley that designed with the smooth cable stringing performance with the durable construction to withstand the harsh construction environments. Its primarily used in the overhead transmission line construction, where the conductors or the optical ground wires need to be laid across the long spans, such as in the mountainous terrain, or the areas with the limited ground access. It features the large diameter sheaves which was commonly made from the high-strength nylon or the tensile aluminum alloy steel, with a deep groove and the high load capacity, this block is able to support the operators to pull the large size conductors without damaging its insulation. The block is typically equipped with lifting rings to ensures that the block can be fixed on the helicopter well, and with the protective coating on the sheaves, this MARSHINE Helicopter Cable Stringing Block is able to ensures the last long durability for the aerial deployment.
The Using Guide Of The MARSHINE Helicopter Cable Stringing Block
Before the aerial constructions, please verify the conductor types and size to choose the right model of your MARSHINE Helicopter Cable Stringing Block, and check your block to ensures its sheave, frame, bearings, and the mounting hardware are clean and well. And fixed on the helicopter slings, ropes, or the connectors properly. When the operation begin, the ground staff need to coordinate with the helicopter team to ensure the precise placement of the blocks on each tower or poles. Then use the tough hook or the swivel connector to attach the block to the tower’s cross-arm or the insulator string, and check whether the block is properly aligned and secure to prevent swinging or tipping during the stringing operations. After that, feed the conductor through the groove of the sheave carefully, and start pulling the conductors at a controlled speed, so that to ensures the sheave rotates smoothly without the friction or jamming. During the operation continue, monitor the conductors to prevent the twisting, block misalignment, or the wear on the sheave. After stringing is complete, detach the block by using the aerial methods or the lifting gear, this depends on the terrain and the tower height. Then clean your MARSHINE Helicopter Cable Stringing Block for any debris or the dust, and lubricate the bearings if needed, and store it in a dry, protected location for the next use.
