has strain and damage the cable.

When the top drive dropped on the drill floor, the height of bracket shall not

make the cable lowered on the floor.

The cable from electric control room should get to mast guide wheel bracket

through ground linearly.

And on above the driller’s cabin.

Caution: The operation of suspension equipment is lesser at this position. Place

mast guide wheel bracket at this position, probability of cable damage is really tiny.

The place of mast guide wheel bracket is determined by following several factors:

The height of mast

Location and type of locating plate

The length of removable devices (drill string, compensator, sheave and rotating

swivel)

The length of cable, besides otherwise requested.

Location of power unit

Placement of mast guide wheel bracket

1. Lift the mast guide wheel bracket on to drill floor by crane or other hoisting

equipment.
