In March 2020, All Erection & Crane Rental Corp. has added LTM 1750-9.1 a 900-ton, 9-axle, 18-wheel AT crane mobile crane, now comes with load capacity tables from refined static calculation methods. These tables will increase lifting capacity values in the entire operating range. The comp...
5.35. Based on this chart the object weight that will be lifted, it can be decided whether the barge is capable or not of doing the job or if another larger crane barge is needed. The deck engines of a sheer-legs crane barge must be adequate to control the barge’s motion in yaw, ...

These calculation results include in particular the maximum load capacity and for instance the current outreach and the entire current geometry and determination of the center of gravity/kinematics. The independently obtained calculation results of the operations planner18on the one hand and the crane ...
represents the height of the gauge above the horizontal plane of the axis of the pivot 16. All of these dimensions and angles normally figure in a calculation to determine the safe load to be lifted by the boom at any radius length D. The present device makes all of these calculations ...
In case of the two distance sensors are provided for measuring their distance from the periphery of a load to be examined through their scanning movement, the location of the center aperture of the load is obtained by calculation of signal outputs of the two distance sensors together with the ...
the calculation of deceleration from one truck to the next can be off by a factor related to the tolerance within the system. Such a tolerance deviation in determination of deceleration can cause a brake energy imbalance in the braking effort among trucks linked in a chain. Without an energy ...
STATUS is set equal to 4 after a successful calculation of tx and Tx, and the routine, therefore, allows 4 passes with the counters 450-1,470-1 enables. If the counters remain disabled for five consecutive passes through the routine, this is taken as an indication that wheel speed is ...
