Safety Devices

500t gantry crane Safety Devices:

The safety equipment of the 500t gantry crane includes a variety of mechanical and electrical protection devices designed to ensure the safety of the operator and equipment. These safety devices are designed to provide maximum safety during crane operation and prevent accidents. The details are as follows:

1.Limit switch and safety brake:

The upper limit switch and lower limit switch of the lifting mechanism ensure that the hook operates within a safe range and avoids excessive winding or excessive lowering.

The safety brake can start quickly in unexpected situations (such as motor loss of power) to ensure that the lift will not accidentally fall.

2.Overload limiter and load display:

The overload limiter monitors the weight of the items being lifted and, once the maximum rated load of the crane is exceeded, will sound an alarm and stop the lifting operation to protect the crane and avoid structural damage.

The large screen display is used to display the current load weight in real time to remind the operator to pay attention to the load.

3.Anti-collision system and audible and visual alarm:

The anti-collision system uses radar or infrared detectors to detect obstacles within the working range and prevent collisions between the various components of the crane.

The audible and visual alarm system reminds the operator to take timely measures through sound and light when the crane is near the end of its track or there is an operation anomaly.

4.Protective railings and buffers:

The high-altitude operating platform and walkway are equipped with protective railings to ensure the safety of the operator when working at a high altitude and prevent accidental falls.

The buffer is installed on the walking mechanism of the crane, which can reduce the impact force when it encounters the end of the track or other obstacles, and protect the equipment and structural stability.

Control Mode

1.The control mode of the 200-ton door engine mainly includes the new mode of "one cabin multi-machine" cooperative operation and "one pair two operation". These modes enable remote control through automation technology, significantly improving operational efficiency and safety. In the control mode of the 200 ton door engine, the cooperative operation of "multiple machines in one cabin" is a key innovation point. The mode includes the cooperative operation of the door engine and the door engine, and the door engine and the mobile machine. When working in the same cabin, the amplitude shifting mechanism of two door engines may collide. By installing anti-collision radar sensors and using software algorithms to reserve a safe distance, the collision of two engines can be avoided. This dual anti-collision strategy of hardware and software ensures the safety of cooperative operation between door machines. At the same time, the collaborative work between the door and the mobile machinery has also been improved, and through real-time position data interaction and image recognition technology, the avoidance of the grab and the mobile machinery can be achieved to further improve the safety of the operation.

2."One to two operation" is another important control mode innovation. Drivers can now operate two door machines from a single console, transforming from the traditional "one person, one machine" manual operation mode to automation and remote control. When the two door machines are running at the same time, the operation table can be switched at will, allowing the driver to take over the operation of any door machine at any time. If there is a problem with the automatic operation of one of the door machines, the system will automatically switch to the door machine, and the driver will directly intervene to ensure the safety of the operation.

3.The application of these control modes not only greatly reduces the driver's work intensity and safety risks, but also improves the operation efficiency to a certain extent. According to statistics, this mode of automation is 5% more efficient than traditional manual work, while providing a safer and healthier working environment for workers, and bringing substantial economic returns to the enterprise.
