What kind of load chart does a crane need?
What kind of load chart does a crane need?
This chart takes into consideration both the line pull of the hoist drum of the crane and the safe working load of the wire rope. Some load charts include the available line pull for each layer of wire rope.
How to determine the available line pull on a crane?
To determine the available line pull first determine the type of wire rope being used, then how many parts of line. Intersect the two columns and you will get the available line pull on the crane. This chart takes into consideration both the line pull of the hoist drum of the crane and the safe working load of the wire rope.
What do you call the pinned boom extension on a crane?
Manufacturers refers to the pinned boom extension on their crane chart as a jib, fly, or boom extensions. These are pretty much the same things, they just could not agree on a name. This crane load chart on the left is a typical load chart for a Link Belt to use when you are lifting with the fly.
Is it safe to operate a crane over the side?
For the sake of crane safety operating a crane over the side without the outriggers properly extended can lead to loss of backward stability with the counterweights installed. This limit is based on stability of crane or the weight necessary to tip the crane over.

What causes a wire rope to fail on a crane?
Tension failure is caused by overloading of the wire rope. The overloading can be based upon the original strength of a new wire rope or for the remaining strength of a used wire rope. When a wire rope has failed due to excessive tension, the broken rope will show one end of broken wire coned and the other cupped.
What are the terms used in the crane industry?
Crane Industry Terms Many terms are used by crane operators which refer to crane function, assembly, operation and maintenance. The following glossary provides a list and brief definition of fundamental terms used in the crane industry. Accumulator A container in which fluid is stored under pressure as a source of hydraulic energy.
When does a crane have an overload condition?
It compares this lifting condition to the crane’s rated capacity, provides an audible visual signal when the loading conditions approach the rated capacity, and when the rated capacity is reached and/or exceeded, it limits crane functions that would result in an overload condition.
