We all know that the truck crane is a relatively dangerous operation method. A slight inadvertent operation during the operation can easily lead to danger. The five-ton truck crane belongs to a relatively large-scale machine and it is necessary to understand the precautions before the operation. Help reduce the probability of danger, then what are the five-ton truck crane attention?
The state of the driver and the proficiency of the operation will directly affect the operation of the crane . Therefore, the driver who operates the truck must be professionally and safely matched. At the same time, the driver can operate the machine skillfully to operate the machine. No experience is forbidden. And the driver of the certificate operates the lifting equipment. Drivers must maintain a good state of mind during their work. Therefore, they must not smoke, drink alcohol, or eat foods that may affect their spirit.
The truck crane must be coordinated by the driver and the lifter to operate normally. Therefore, the driver and the lifter must maintain good cooperation during the operation. At the same time, he obeys the arrangement of the commander, and the driver can refuse the operation in a potentially dangerous environment. Drivers and lifters must comply with operating rules and regulations.
Before the work, it is necessary to inspect the wire ropes, brakes, and the hydraulic devices and safety devices in the lorry crane . At the same time, the lifter needs to avoid the lifting boom as much as possible under the load, and at the same time it must be stable before the lifting and landing of the jib. Cannot change operation device.
When lifting the object, the crane first needs to adjust the position of the object to about 10 cm from the ground, and then check the stability of the crane and the brake to confirm that the crane and the brake can operate normally.
The driver must first press the horn before operating the lorry crane to perform the operation with confirmation that the commander's hand gesture is correct. If it is found that the commander indicates a faulty phenomenon, the driver must stop immediately after sending a signal indicating that the emergency stop signal is in place. Unsafe factors reduce the probability of danger.
CNC lathe is a machine tool for machining metals and other materials, which controls the movement of the table and tools by a computer or other digital device to achieve high precision and efficiency. Compared with traditional lathes.
Structural characteristics of CNC vertical lathe:
CNC vertical lathe is a CNC vertical lathe whose main structure is base and single column type structure with table, fixed beam, square ram and single tool holder structure, which is an economic CNC vertical lathe with high rigidity and high cost performance. The casting process of CNC vertical lathe is large in volume and complex in structure, the amount of iron liquid poured is large, the cooling time of the casting is long, and casting defects such as shrinkage, shrinkage, pore, crack and substandard mechanical properties are easy to appear, and it is difficult to control the production process. The base, column and beam of CNC vertical lathe are made of high-strength cast iron with good shock absorption; the large span hardened guide rail has good wear resistance and long-lasting precision maintenance. Symmetrical box structure can carry heavy cutting with high torque. The ram adopts square structure, with good precision. Fixed cross beam, good rigidity and high precision. CNC vertical lathe single tool block structure, stable and reliable precision. Centralized machine operation panel â—‡Makes the operation more convenient and quick. It can process various internal and external cylindrical surfaces, conical surfaces, circular curved surfaces, etc. CNC vertical lathe is suitable for processing parts such as motor shells, large and medium-sized disk sets and covers. It is suitable for electromechanical, automobile, wind power, engineering machinery and other industries.
