Pole Erection Unit
1. General description
The apparatus is mounted on the reinforced chassis of a Bedford vehicle with full power
take-off facilities. The vehicle cab provides seating for the driver and one passenger and a crew compartment behind the cab enables a third man to be carried if and when required. Two
full length lockers one on each side of a central gangway, provide adequate accommodation for all the tools and stores required to be carried on the unit. Provision has been made for a Ladder, Extension, No. 5 to be carried on the roof of the
near side locker. Two pole bolsters one behind the cab and one at the rear of the lockers, have been provided. They are designed to carry approximately 30 cwt. of poles in three banks. The front bolster also supports the derrick in its stowed position.
The apparatus consists of a hydraulically operated derrick with telescopic boom, mounted on the
near side of the chassis at the rear. On the extendible portion of the boom are mounted a
pole hole borer, winch and at the extreme end, a pole claw; all are
hydraulically operated. Stability of the unit is ensured by means of two stabilizing jacks which can be lowered hydraulically before putting the unit to work. Rotation of the derrick is
non-continuous but extends 3750 in an anti-clockwise direction from its diagonally stowed position on the bolster. All movements of the derrick,
pole hole borer, winch, pole grab and jacks are controlled from a panel at the rear of the vehicle. The function of each control lever is clearly marked on the panel. An engine speed governor, remotely controlled from the panel, is also provided.
2. Auxiliary equipment
A hydraulically operated pole jack and a backfill rammer are provided with each unit. Both are operated from hydraulic connexions with
quick - couplers at the rear near - side of the vehicle and are controlled from the panel.
