Sep 30, 2020 · It is a misconception to assume that wood timbers or engineered crane pads evenly distribute outrigger loads to the ground or always distribute the load over 100% of the pad,” he says. “The harder the ground is, the more the ground resists deflection, which reduces the pads ability to distribute the load.

Jan 10, 2020 · Outrigger: A beam which extends from the lower works of a crane to increase the crane's stability. The bea may be either extendible/retractible or fixed length and typically utilize some type of pad to distribute loads to the ground surface.

1. Crane Weight The maximum weight of the crane to be used 50,000kgs (worst case scenario) 2. Load The maximum load to be lifted 22,000kgs + Load 1,500kgs 3. Outrigger Load Point load = (1+2) x 100% = (50,000 + 23,500) x1 = 73,500kgs or 73.5t 4. Ground Type Ground mes in granular and hesive types. Bearing Values BS: 8004 5. Mat size

For the Spreader Pad Calculator to work effectively you'll need maximum load per outrigger and the maximum allowable ground pressure in the same unit of measurement. Don't worry, if you don't know the ground pressure - the calculator will ask you for the surface materials and you'll be able to select the most appropriate type.

Apr 01, 2020 · Outrigger Pad: A wood, metal, or synthetic structural element that is placed on the supporting surface and on which bears the crane's float that is used to distribute the outrigger load over a larger area.

This calculator will provide guidance on the required size of outrigger pads needed for equipment that use extended outriggers or stabilisers. It does not calculate for equipment with wheels . Please call us on +44 (0)1952 671403 if you need further assistance.

Dec 30, 2022 · You need to calculate the potential force that will be exerted on one pad before deciding whether or not it is safe to perform the lift. Add the weight of the crane itself to the weight of the load you are attempting to lift to get the total weight that will be puHDPEng down on the outrigger pads.

Calculations for Outrigger Pads I was qualified as a crane operator many years ago and recently found some training materials from that class, which provide the following rOkaymmendations. When mpaction information is available or a pocket penetrometer is used to measure soil mpaction, lift planners may use the following calculations to

Jul 19, 2012 · • Never use outrigger pads or cribbing that are smaller than the outrigger foot itself. Doing so will ncentrate, rather than spread the load, creating a point loaded setup that uld fail. • Outrigger feet must be smooth and free from debris in order to be stable and achieve solid ntact with a Safety Tech outrigger pad.

Oct 13, · Outrigger pads or mats provide support for crane outriggers and help spread load to the ground. Worit out the Outrigger pad or mat size is a 4-step process: Calculate the FORCE exerted on the ground by the crane (i.e. Manufacturer’s software or (crane weight and attachments, plus load weight and rigging) x 0.65)
