6.3.2

Chain and sprocket drives

Two types of chain and sprocket drives are available:

•

Shaft Drive

•

Counterweight Drive

6.3.2.1

Chain and sprocket shaft drives

In the Shaft Drive arrangement, the motor drive utilises a taper bore sprocket and a roller
chain to drive a shaft running between the counterweight pulleys.

The motor assembly is supplied fitted to an adjustable bracket so that the correct chain
tension can be set.

The Shaft Drive arrangement can accommodate one or two sash wires.

6.3.2.2

Installing the chain and sprocket shaft drive

1.

Fit the taper bore sprocket to the shaft and ensure that the sprocket is securely fitted.

Where possible positioned the motor drive and sprocket centrally on the shaft. The
motor assembly should be fitted to a rigid framework to support the motor.
