Rated dynamic load

≥2.5kN/㎡

Speed

0m/s-0.30m/s(±8%)

Mesa gap

The horizontal gap between the lifting platform and the fixed floor should not be greater than 12mm

Stopping accuracy

≤±3mm

Noise

Noise value ≤45dB(A)

Safety switch

The lifting platform has an upper limit switch and a lower limit switch. After the limit switch is triggered at the rated speed, the equipment can stop running

Anti-shear and anti-crush protection devices

An anti-shear protection device should be installed at the position where the electric drive lifting platform and its peripheral equipment may produce shear, so as to protect against shear damage that may be caused by relative motion.

The buffer distance of the anti-shear protection device shall be greater than the maximum operating distance of the device when the anti-shear protection device stops under rated load and rated speed.

Locking device

A platform raised by a wire rope or chain shall be provided with a locking device at a position where its platform is used as a stage floor and for long-term stationary use.

Light signal and light indicator

The necessary equipment running lights and buzzers that can be turned off should be set up without affecting the audience's viewing of the performance

Overspeed protection

The lifting platform is set with overspeed protection when the input speed exceeds the set value, the system cannot input

Emergency shutdown control element

The emergency stop switch is provided on the control platform, which has the function of emergency stop, and the emergency stop is effective

Electrically controlled safety loop

The motion state response of the control element and the device is consistent and effective

Warning signs about safety

The console warning signal is consistent with the operating state of the equipment and effective:

The real-time status of the safety signal can be monitored on the console human-machine interface.
