What do you need to know about Crane Safe Load Indicators?
What do you need to know about Crane Safe Load Indicators?
To alert for maximum load – of course, this is the basic purpose of the crane safe load indicators. To alert for maximum radium exceeded – so the crane’s operator knows that the load might be at risk of falling if it is raised any further.
What is gradeablity in Crane and rigging terms?
Devices incorporated into the anti—two block system or rated capacity indicator system which will disable the crane function of winch up, telescope out and or boom down (as applicable) as two block or overload situations approach. Gradeablity The slope which a machine can climb expressed as a percentage (45° equals 100% slope).
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.
Where can I find a capacity chart for a crane?
Cantilever Any unsupported boom or jib section that projects beyond the supporting point. Capacity Chart A chart for the crane which gives rated lifting capacities for the crane under different load conditions and setups. Capacity charts are found on the crane or in the Crane Rating Manual.

Can a pick and carry crane be used on soft ground?
Safe Working Loads are based on freely suspended loads with the machine on a firm, level (max. slope 1% gradient / 0.6°) and uniform surface. Lifting or travelling with a load on soft or uneven ground can be hazardous and will reduce the capacity of the crane. No attempt shall be made to drag the load along the ground in any direction. C1325-/1-5
Cantilever Any unsupported boom or jib section that projects beyond the supporting point. Capacity Chart A chart for the crane which gives rated lifting capacities for the crane under different load conditions and setups. Capacity charts are found on the crane or in the Crane Rating Manual.
