400 TON, Reel Hub Drive System (RHD)

400 Tonnes Reel Hub Drive

The Reel Hub Drive System consists of two identical Towers running on two parallel tracks. To denote which side of the individual assembly belongs, tower “A” and “B” markings are printed onto the assemblies for better identification.


The tower winch is designed to handle reel sizes from 5.2m to 11.4m in diameter, with a gross weight not exceeding 400 ton. The operation tension
is set at a constant tension of up to 15 tonnes, but at varying line speed during payout.


Two sets of 75kW /88kW electrical-powered pumps provide hydraulic power to 8 units of hydraulic motor (4 motors on each drive tower). Each motor is coupled to a multi disc brake and a planetary reduction gearbox driving a common reel drive via the bull gear.

  • General Description

The Reel Hub Drive System consists of two identical Towers running on two parallel tracks. To denote which side of the individual assembly belongs, tower “A” and “B” markings are printed onto the assemblies for better identification.

The tower winch is designed to handle reel sizes from 5.2m to 11.4metres diameter with a gross weight not exceeding 400 ton. Please see the setup section in details for the varied reel diameter setting. For this operation, the operation tension is set at a constant tension of 15 tonnes, but at varying line speed during payout.

Two sets of 75kW /88kW electrical-powered pumps provide hydraulic power to 8 units of hydraulic motor (4 motors on each drive tower). Each motor is coupled to a multi disc brake and a planetary reduction gearbox driving a common reel drive via the bull gear.

Included in the Tower are lifting mechanisms and the hydraulic drive mechanisms.

The tower winch is made up of the following modular components:

Transportation

For the RHD transportation, both the weight and overall dimension of each assembly need to be considered for the delivery, as shown in the following table

In general, all the assemblies can be lifted by the standard lifting equipment of chain and crane. User is to take note of the weight of the assembly and not to exceed the crane lifting capability. Proper securing has to be ensured to prevent any shifting of the assembly during movement.
