Pillar jib crane is a common lifting equipment, widely used in construction sites, port terminals, warehouses and factories. When using pillar jib crane for lifting operations, the operating procedures must be strictly followed to ensure the safety of personnel and prevent accidents. This article will introduce the precautions for cantilever crane operation from different aspects.
Before using floor mounted jib crane, operators need to undergo relevant training and assessment, master the structure and working principle of jib crane, understand the hoisting and lifting specifications, be familiar with relevant safety operation regulations and emergency measures, and master relevant operating skills. Only through professional training and assessment can operators be guaranteed to have sufficient safety awareness and operating ability.
Before operating floor mounted jib crane, necessary inspections and preparations need to be made for the lifting site. First, check its operating status and confirm whether its components are intact, without damage and failure. Check the load-bearing capacity of jib crane to ensure that it can meet the needs of lifting objects. At the same time, check the environmental conditions of the lifting site, such as the flatness and load-bearing capacity of the ground, as well as the surrounding obstacles and personnel conditions, to ensure the safety of the lifting site.
When operating a column mounted jib crane, it is necessary to correctly select and use the sling. The selection of the sling must match the nature and weight of the lifting object and comply with national standards and specifications. The sling should be checked for damage or wear and should be firmly and reliably fixed. The operator should use the sling correctly, connect it to the hook of the jib crane correctly, and ensure smooth traction and pulling between the sling and the object.
When the lifting object moves under the hook of the column mounted jib crane, it should be balanced to prevent shaking, tilting or rotation, so as not to cause harm to the lifting site and personnel. If the lifting object is found to be unbalanced or unstable, the operator should stop the operation immediately and take appropriate measures to adjust it.
In short, the operation of the pillar jib crane requires strict compliance with the operating procedures to ensure the safety of personnel and lifting objects. Correct selection and use of slings, close cooperation with the command signalman, attention to the balance and stability of the lifting object, and attention to various alarms and abnormal conditions are all precautions for operation.
