Dec 15, 2018 · As discussed earlier in this post, load angle is the angle between the field flux and the resultant air gap flux. This means, as the mechanical power input to the synchronous generator is increased through prime mover, the field poles will be dragged ahead of the stator pole or flux. This in turn will increase the load angle. An increased load ...

When a load is allowed to hang free, the natural choke angle is about 135°. If the angle is less than 120°, you must adjust its Choker Hitch Working Load Limit by the appropriate choke factor from this table. Choker Hitch WLL x Choke Factor = Adjusted WLL Sep 30, 2019 · This table is based upon the joint at rated load and life. Going above the rated load or angle will decrease the u-joints life. As a general rule of thumb, for each doubling of the operating angle, RPM, or load, the lifetime of the joint is decreased by half. Rated lifetimes are on the order of 3000 hours.

Oct 01, 2014 · The basic equations in this case are slightly different from the equations of the vertical load due to the introduction of the inclination angle, α, of the load. The Mohr–Coulomb failure criterion requires that the angles between the load axis and both the left leg ( r L ) and the right leg ( r R ) of the triangle remain θ 1 − ( 1 / 4 ...
Multiply the chain's working load limit by the cosine of the angle between the chain and vertical to get the adjusted limit. For example, if 1000 lb rated chains are at 45 degrees to the vertical their safe working load limit is reduced to 707 lbs. For overhead lifting where human safety is involved you should use Grade 80 or above.
Taking all of this account, the ISO formulae for the calculation of surface durability of bevel gears (ISO 10300-2 and ISO 6336-5) were the basis to determine the objective function for evaluation of the maximum torque on a pinion according to the higher load capacity. Where: K A Load application factor K V Dynamic factor

Always take into account sling angles to calculate changes in the sling Work Load Limits, when used in choker and non-perpendicular vertical, basket or bridle configurations.
This is incorrect. If the real power load is 10kW, at unity power factor the kVA is 10kVA. If PF = +/-0.95, on a real load power of 10kW, kVA is 10.52kVA. Leading PF is caused by a net capacitive load and the effect of it is the same as a lagging PF (inductive load); the supply current is higher than for a truly resistive load.
