How much does the counterweight on a crane weigh?

The maximum load that the crane can lift is 18 metric tons (39,690 pounds), but the crane cannot lift that much weight if the load is positioned at the end of the jib.

In this way, what is a counter weight system?

A fly system, or theatrical rigging system, is a system of rope lines, blocks (pulleys), counterweights and related devices within a theater that enables a stage crew to fly (hoist) quickly, quietly and safely components such as curtains, lights, scenery, stage effects and, sometimes, people.

What is the counterweight made of?

By balancing the weight, they secure a safety performance of tractors, forklift trucks, cranes, excavators and others. The manufacturers prefer using either full cast iron, full concrete, or a mix of concrete and metal bits. For example forklift counterweights are commonly made of metals for maximum space utilization.

Why do crankshafts have counterweights?

For some engines it is necessary to provide counterweights for the reciprocating mass of each piston and connecting rod to improve engine balance. These are typically cast as part of the crankshaft but, occasionally, are bolt-on pieces.
