The test-bed for anti-falling safety device of gear-rack construction lifter is used to simulate the actual cage braking process by the safety device stopping high-speed inertia flywheels, with the braking torque and braking distance to be detected to judge whether the braking capacity of the safety device is qualified or not.The loaded calculation method for inertia flywheel of the safety device test-bed is deduced, in order to figure out the required inertia values for corresponding flywheels of safety devices in different specifications on the test-bed with determined reduction ratio based on statistical data from the actual falling tests.A test-bed of variable-load anit-falling safety device is developed according to the calculation results.
