What are the safety measures for Hiroko's stacker?

Kubik stacker safety measures are as follows?

1. Rope loosening protection device: When the lifting wire rope of the stacker is loosened, the power supply of the lifting motor is automatically cut off, and the brake of the loading platform is stuck on the column to prevent the loading platform from falling. ?

2. The stacker has an overload protection device, which automatically cuts off the power supply of the hoisting motor when the load exceeds 10% of the rated hoisting weight.

3. The stacker is equipped with double protection devices of lifting limit switch and mechanical buffer. When the cargo platform exceeds the normal lifting stroke and reaches the upper and lower limit positions, the switch triggers to automatically cut off the power supply of the lifting motor, and the cargo platform will stop running. In addition, buffer blocks with good impact resistance are added outside the upper and lower limit positions, forcing the cargo platform to stop running. ?

4. The stacker is equipped with double protection devices for operating limit switches and mechanical buffer blocks. When the stacker exceeds the normal running stroke and reaches the left and right limit positions, the trigger switch automatically cuts off the power supply of the running motor, and the stacker will stop running. In addition, buffer blocks with good impact resistance are added outside the left and right limit positions, forcing the stacker to stop running. The force acting on the buffer block when the stacker is walking at high speed with full load is calculated. ?

5. The stacker is equipped with a manual emergency stop button, which can cut off the main power supply of the stacker in an emergency. ?

6. Electrical interlocking protection of the stacker.

7. The multi-position stacker is equipped with interlocking device to ensure that the stacker can only be operated from one position at a time.

8. The control modes should be interlocked to ensure that only one of manual, semi-automatic, automatic and computer online control is allowed at a certain moment.

9. When the fork is not in the middle position (it is not in the correct position when it is closed) or the fork moves, the walking and high-speed lifting of the stacker will be locked; Forks will be locked when the stacker is running, lifting at high speed or the stacker breaks down.

10. The control circuit shall also have the following conventional interlocks and protections: voltage loss protection, zero position protection of operating switch, forward and reverse motor interlock, interlock of different speed classes, short circuit and overload protection. ?

1 1. The stacker is equipped with audio alarm device. Before starting the operating mechanism, an audio signal should be sent out first. ?

12. The stacker has the functions of fault alarm and self-diagnosis. ?

13, all roadway openings/doors automatically cut off the power supply when the stacker is powered off in an emergency.

14. The cargo platform is equipped with cargo oversize and collapse detection to avoid accidents caused by cargo exceeding the stacker. ?

15. The cargo platform is equipped with actual or false detection of the cargo position to confirm whether there is cargo at the cargo position, so as to avoid repeated warehousing. When there is any cargo in the cargo position, the transportation will stop and give an alarm.

16. Forks are equipped with limit switches and mechanical stoppers. Forks are equipped with a first fork and a second fork for centering detection to prevent the stacker from misoperation when walking and lifting. At the same time, there are limit switches and mechanical stoppers at the terminal of the fork to ensure the safety of the stacker in the track roadway.

17. The front fork is equipped with a torque limiter. When the fork encounters an obstacle in the extension process, when the resistance reaches the specified value, the torque limiter of the fork will slip and the fork will stop extending.

18. There is a track cleaner in front of the walking wheel of the stacker. ?

19. The safety factor of hoisting wire rope selected for stacker is greater than 6. ?

20. The safety protection device shall be installed in a position convenient for inspection and maintenance.
