Brake test (acc. to DIN 56 925)
No-load torque (without load) of double safety spring loaded brake with torque measuring
device test.
No-load torque minimum 3 Nm resp. manual hand force 12 N with 250 mm crank arm
length.
♦ With a low deviation from Mmin results in an erosion border of the brake spring and
brake drum, the braking mechanism must be exchanged.
♦ When the nominal crank pressure is exceeded in the torque in any direction, the brake
will break.
Nominal manual crank pressure with full load 180 N with crank arm length from 250 mm
Nominal operation torque 45 Nm
Re-lubrication of the double safety spring crank and double safety spring locking device only
