SPECIALISED CONCRETE ROAD MACHINE
An important aspect of maintaining the integrity of a concrete pavement is the placing of correctly located expansion joints with accurately placed steel dowels as part of the joint design. A machine designed by eclipse engineering places steel dowels as part of a complex paving train. Operating at a rate of 2 m/min the machine places three 20 mm diameter, 840 mm long steel rods, simultaneously at a preset frequency, into wet concrete at a prescribed depth. Machine operation is controlled by a variable hydrostatic transmission with pneumatic actuated dowel placing mechanism. Each system is powered by a separate diesel engine so that in the event of an engine failure the remaining engine can provide power for both systems. (TRRL)
