Problems solved by technology

[0002] Crane is an important mechanical lifting equipment with a wide range of applications. Therefore, it is very important whether the crane can be operated in a safe and standardized manner. It is also very important to protect the crane platform. At present, it is used to install guardrails around the crane. The platform of the crane is protected. However, the existing crane guardrail structure is very complicated, and the height of the guardrail cannot be adjusted freely, and the scope of use is single. Therefore, it is necessary to provide a simple structure, reasonable design, safe and reliable. It is very necessary to adjust the height of the crane guardrail
