GENERAL

The Coles Illustrious is a truck-mounted, diesel-electric, fully slewing crane on an 8 x 4-wheel drive chassis fitted with telescopic outrigger beams, fully sprung front axles and articulated rear bogie.

The diesel engine on the slewing superstructure is directly coupled to a variable speed generator which energises the electric motors of the hoist, derrick and slew motions. Direct current is supplied to the motors at a potential which can be varied at will from zero to maximum.

Each crane motion is controlled by an interlocked pair of heavy duty reversing contractors operated by pilot switches in the operator's cab. Coles advanced control system and built-in safety devices automatically safeguard the machine and load, The operator can select any motion, irrespective of the engine speed, whereupon the electrical equipment introduces the motion without shock to electrical or mechanical components. No restraint is placed upon the crane operator, enabling the optimum operating cycle to be achieved.

The chassis is specially designed for crane service, combining maximum stability for lifting duties with excellent travel performance. Drive to the rear bogie is taken from a chassis-mounted diesel engine via a multi-speed gearbox and two-ratio auxiliary gearbox.
