KBK, the abbreviation of Kombiniert Kran in German, means modular crane. It is a patented product (patent expired) of German Demag (DEMAG). It is composed of device, walking trolley and some functional components. All modules are standard components. The lifting device mainly adopts electric chain hoist. It can also hang some manipulators or welding torches. It can be used as a tool slide. Let’s take a look below. Its use steps:
1. When the various mechanisms of the crane are moving, and when there are people on the same-span crane or the moving route of the hanging object, a warning signal must be issued; 2. You must be concentrated, and it is forbidden to read, eat, call, chat, etc. during use.
3. Start each mechanism with an empty vehicle first, and judge whether each mechanism is operating normally.
4. When manipulating, it must be "stable, accurate, fast, safe and reasonable" and always be steady, steady, and steady.
5. The command signal must be followed. No driving is allowed until the signal is unknown or the commander has not left the dangerous area.
6. The driver only listens to the driving signal issued by the commander appointed before the job. Anyone who issues a stop signal must stop immediately.
7. Although the commander sends a command signal, he should not drive when he is not looking at the suspended object.
8. The crane's controller should increase (decrease) speed by gear, and it is forbidden to turn the control handle from the forward position to the reverse position for stopping (only allowed under special circumstances).
9. During the operation, if you hear abnormal sounds, you should immediately stop and cut off the power for inspection, and the lifting objects should be safely put down.
10. When the working crane encounters a sudden power failure or a sharp drop in line voltage, the controllers should be returned to the zero position as soon as possible, the main power switch should be cut off, and the commander should be notified.
11. When the lifting mechanism brake suddenly fails during work, be calm and calm. If necessary, turn the controller to a low-speed gear and perform slow and repeated lifting actions. At the same time, drive the big or small car, select the safe zone, and put down the heavy objects.
12. When the driving is out of control, you should reverse the car or press the emergency stop button according to the situation.
13. When the tower crane makes abnormal noise, or has misoperation, or finds that the tower crane's safety protection device is out of order, check it and make a record.
14. When a project is completed, after the tower crane is disassembled, detailed inspections should be carried out by engineering and technical personnel and professional maintenance personnel, and records should be made.
I hope everyone should follow the steps when using KBK cranes. Safe use of cranes will increase the safety of cranes.
