T IAULAGE No. 453 represents a belt-driven double endless rope
TT haulage, having strong, machine-moulded, double helical spur
gearing for the first gear. 50 H.P. size wheel has 90 teeth, 2 in.
pitch, and a 7 in. working face with strong box section arms.
Usually made of specially tough cast-iron, but where liable to
sudden strain cast-steel is recommended. Clutches are of coil type,
but band clutches may be substituted. A screw type clutch gear
enables haulage to pick up its load very gradually. Intermediate
wheels, including driving wheel, have machine cut teeth with
broad faces, ensuring smooth and practically noiseless running.
Large split wrot-iron pulley, keyed to driving shaft, suits a belt of
ample width to prevent slipping. Fleeting wheels are shod with 6
removable chilled cast-iron trods of a “ C ” section shape, which
have proved the most satisfactory type, after experiment. Bed-plate
is of rolled steel joists, with ends composed of rolled channels and
suitable chequered foot plate and connecting gussets, angles, &c.,
very strong and rigid. Instead of brakes Carron Company’s special
silent sliding pawl can be fitted, which works most satisfactorily.
Main bearings are syphon lubricated, remainder being fitted with
self-oiling rings.
