Spurs Large Vessel Line Cutter Installation Complete
The photo # 2 above shows a completed installation of Line Cutter Model LV-60/48. The rotary cutter
and stationary cutter assemblies have had the marrying screws and .015 shims removed and
now operate independently. The propeller has been rotated to verify clearances between the
two opposing blades. A box to hold the stationary cutter assembly has been welded into the
rope guard; the stationary cutter assembly is screwed into the welded box and is easily
removed for service. The rotary cutter assembly is fastened
and mounted to the propeller hub. The cutter blades always remain .010 -
.015 apart due to a guide mechanism and movable cutter shaft that is built into every
cutter. As the cutter blades pass during each rotation, there is no contact and this
assures no wear-no maintenance. However, when a line is cut or the shaft moves forward or
aft (end play), there is one revolution of the prop; at that time, the blades contact but
only for one quick adjustment during that revolution. The cutter blades are then
automatically centered due to the centering principle built into the mechanism.
