Is there a rule of thumb for outrigger support?
Is there a rule of thumb for outrigger support?
No rules of thumb, no wing and a prayer, no best guess, just a calculation to determine the size of cribbing/blocking required. A key thing to remember is that as a crane works and rotates over the various corners and quadrants, the load will shift and at any one time a greater load will be placed on one outrigger than on the others.
Can a load pass over a single outrigger?
We have seen studies that show as a load moves through its lift and if it passes over a single outrigger, the force upon it can be close to 100% of the load.
How to determine the blocking dimensions of an outrigger?
This is the PRESSURE the soil can withstand. Determine AREA by calculating FORCE รท PRESSURE Find the square root of the area to determine the blocking dimensions
How do you calculate outrigger support for a crane?
It can be done. With some basic information on the crane weight, gross load weight and ground bearing pressure, then the size of outrigger cribbing for adequate support can be calculated. Obtain the Ground Bearing Capacity (GBC) permitted for the soil you are set-up on. This is the PRESSURE the soil can withstand.
How to retract and deploy the outrigger?
– if the outriggers are on a trailer, you also have to press the “trailer modifier” key, which is normally “LeftShift”. – so you need to attach the trailer to a truck, and then, sitting in the truck, press “LeftShift-Q” or “LeftShift-E” until you get a message like “Outriggers are fully retracted”.

When did the JCB 212 backhoe come out?
Discussion in ‘ Tractor/Loader/Backhoes ‘ started by CANNONMAN1, Feb 14, 2010 . Anyone have any experience with the JCB 212S?
Where is the shut off valve on a JCB 212?
There’s a shut off valve for the quick release located on the quick hitch. The lever should be straight up perpendicular to the hydraulic line at all times except when releasing the quick hitch. Move the lever down until it’s parallel to the hydraulic line when you want to operate the quick hitch. Click to expand…
