It is common practice to design for the calculated or estimated maximum load
. If the engineer is fortunate enough to have an operating machine at his disposal, he might instrument it and observe the pressure transients that occur at the instant the operator shifts the directional control valve; the cylinder first begins to move, then extends.
Initial load increments were large but were reduced as the team approached its estimated maximum load
. When a team was unable to complete a lift, the load was reduced in small increments (3-10 kg) until a lift was completed or until the last load lifted successfully (prior to first failure) was reached.
