Other Details

On the top of standard is mounted a headgear fabricated from rolled section. The drive is through vee belts from a Lifting Mechanism. Electric motor via flywheel and reduction gear to the lifter shaft. A friction lifting arrangement is fitted on the lifter shaft which runs on double ball bearing and central phosphor bronze bushes which also acts as a support. The friction lifter consists of a constantly rotating drum around which is arranged a steel band with friction lining. This band is anchored at one end to a drum stud in the lifter drum and the other end is carried by a camshaft running through the lifter drum and actuated by a lever. To this lever is attached the pulling cord. When the cord is pulled it tightens onto the rotating capstan bush and through the camshaft causes the friction band to grim drum. There upon the lifter drum is rotated thus lifting the tup by means of a lifting belt. A buffer provides a stop for the lifter drum in its extreme position. A spring ensures free fall by immediately disengaging the friction band from the drum immediately the pulling cord is released.
