1 INTRODUCTION TROWEL REPAIR
1.7 Application
The CT series of trowels are modern, high production
machines intended for floating and finishing freshly poured
concrete slabs. The machine’s good balance, adjustable
handle, and easily accessible controls add to operator
comfort and productivity. An automatic stop switch, or a
combination of an automatic stop switch and an operator
present lever, provide added operator safety. Finishing
rates will depend on operator skill and job conditions.
1.8 General Description
For the CT product line of trowels, engine power is
transferred through a centrifugal clutch and V-belt to the
gearcase and down to the trowel blades. The four trowel
blades are mounted on a spider assembly mounted on the
gearcase output shaft. The spider assembly adjusts the
trowel angle by being raised by the yoke-trowel blade lift.
The trowels can be tilted from 0° - 15 °. The speed
of the trowels ranges from 60-165 rpm, depending on
the model.
