		The counterweight, which is usually made of a dense material such as concrete or lead, provides an anticlockwise moment that balances the load on the crane.
		The bowling ball according to claim 1 in which the counterweight is disposed in the shell of the bowling ball at a position intermediate the finger grip hole locations so as to symmetrically compensate for the absence of material in the finger grip holes and thereby balance the bowling ball.
		A counterweight is located in the ball, near its outer surface at a position intermediate the locations for finger grip holes, to balance the ball in compensation for the loss of weight due to removal of the core and shell material from the grip holes when the finger holes are formed.

	Demountable gantry, boom hoist and counterweight - Patent 4081081
		Counterweight lift links are connected between the gantry and the counterweight and the back hitch cylinders may be used to mount and demount the counterweight and the boom hoist winch.
		A further object is to provide the counterweight lift links with adjusting means to accommodate changes in the center of gravity of the counterweight and thus assure precise alignment of the openings in the crane and counterweight elements through which the lock pins are inserted and withdrawn.
		The counterweight 35 may then be lowered to the ground by retracting the cylinders 32 and the links 36 may be unpinned at their upper end from the gantry members 31 and folded into the center portion of the counterweight assembly.

	Bowling ball having high density counterweight - Patent 5096193
		The counterweight is formed of a non-metallic material having a density substantially greater in magnitude than the density of the core or shell materials.
		The counterweight provides a concentrated weight mass that increases the degree of freedom in the location and orientation of finger holes to be drilled in the ball.
		A counterweight is a necessary balancing element for any bowling ball which has a body of uniformly dense material and which does not have voids within its interior.

	Counterweight Shaft Feature
		Older Style 19.5" Counterweight Shaft (M12601-B) Older Style 28" Counterweight Shaft (M12661-A) This style counterweight shaft, one piece washerless safety stop and optional extension began shipping with 1200GTO mounts in May, 2006 and continued with the 900GTO's that began shipping in January, 2007.
		We machined matching female threads into the far end of the counterweight shaft, to accept the new 9" extension (M12675) so that you don't have to order the 28" shaft for a larger scope.
		The 9" Counterweight Shaft Extension has a shorter lead-in thread than the full counterweight shafts and should NOT be the piece that screws into the declination axis.

		If the counterweight were not there, the load would tend to tip the crane forwards [clockwise].
		The counterweight, which is usually made of a dense material such as concrete or lead, provides an anticlockwise moment that balances the load on the crane.
		A typical example is counterweights on crankshaft s in piston engine s.

	Technical & Literature - Backstage Tour: Counterweight Rigging
		A simple counterweight system is based on the principle of establishing a balanced set of weights that allow a stagehand to raise and lower various loads with minimal effort.
		The lattice track in which the fire curtain's counter-weight arbor rides is attached to the front wall of the stage and is totally separate from counterweight arbors used to control movement of other elements on stage.
		Attached to the back of each counterweight arbor is a guide shoe that lets the arbor slide up and down between two T-shaped guides, but prevents it from swinging from side to side.

	Elevator with variable drag for car and counterweight patent invention
		Thus, as the counterweight reaches lower points of travel, and conversely the car reaches higher points of travel, the car will become lighter relative to the counterweight, due to the hoist rope.
		In such a situation, the counterweight would not be acting to provide the counterweight benefit as adequately as if the car and counterweight were at more approximately equal vertical positions.
		Similarly, when the car or counterweight is at the bottom of the hoistway and it has to move upward, the motors 62 and 64 on the car and counterweight would drive the sheaves 54 and 58, thereby equalizing the rope tension on car and counterweight.

	Rotary Resurrection home of the budget rebuild.
		The front counterweight is under the front cover, and should never be changed unless a custom engine is built using different rotors.
		The rear counterweight can take one of 2 forms; it can be a flywheel with the counterweight integrated into it (cast) or it can be an automatic counterweight with the 6 bolt pattern for the ringgear to bolt onto.
		Any engine within the same series (86-88, 89-95, etc.) can use the same rear counterweight, regardless of whether it originally was an automatic or a manual, or whether it used a 205 or 225mm flywheel.

		These gathered sheets of lead were believed to have been melted down and then attached to the counterweight of the trebuchet.
		The most efficient way for any counterweight to respond to the force of gravity is by falling in a straight line.
		The hinged counterweight, however, is free to follow a straighter descent to the ground, providing the trebuchet—and eventually the launched stone ball—with an even more devastating power.

	Counterweight a Dobsonian Scope (Site not responding. Last check: )
		For example, if you counterweight the OTA at the rear center of the tube so that the OTA is properly balanced when it is elevated 45°, you have too little counterweight when the OTA is below 45° and too much when it is above 45°.
		The problem with counterweighting at the rear center or rear top of the OTA is that the axis between the counterweight and the offsetting weight at the front of the OTA doesn't pass through the center of mass.
		Where that axis intersects the rear of the OTA is the point where the counterweight should be.
