What Is the Difference Between a Hoist and a Crane?
Lifting machinery is clearly defined in the Regulations on Special Equipment Safety Supervision (Decree No. 114 of 2014 of the State Council).
- Lifting is the movement of machinery or other objects from one place
- Lifting machinery passed
- Working institutions include:
- The basic mechanism of lifting machinery Various lifting machinery have different uses and are very different in structure, but they all have lifting mechanisms to achieve the basic action of lifting. Some lifting machines also have operating mechanisms, luffing mechanisms, slewing mechanisms, or other specialized working mechanisms. Materials can be made from
- Lifting machinery can be divided into light and small lifting equipment according to different structures
- The most important performance parameters that characterize the basic working ability of a lifting machine are the lifting capacity and the working level. Lifting capacity refers to the maximum weight of the weight that is allowed to be lifted under the specified working conditions, that is, the rated lifting capacity. Usually with electromagnetic suction cup (see lifting suction cup) or
- 1) Lifting machinery is usually large in structure and complicated in structure, and can complete lifting movements,
- When purchasing hoisting machinery, enterprises must first comprehensively consider factors such as the scope of use, frequency of work, utilization rate, rated lifting capacity and other factors, and choose a crane that is suitable for the working level of the unit. Conduct market research based on the proposed technical parameters. The selected supplier must be a professional crane manufacturer with a special equipment safety license. And inspect the manufacturer's matching of processing equipment, production standardization, product advancedness, after comparison, choose a reasonable price, good quality, excellent performance, complete safety equipment hoisting machinery. After the equipment arrives, check whether the random technical information is complete, whether the random accessories, tools, and accessories are consistent with the list, and whether the equipment and accessories are damaged or defective, and make a record of unpacking and acceptance. [2]
- The hoisting machinery installation team can choose a manufacturer with installation qualification to form a one-stop service model for manufacturing, installation and commissioning. In addition, the selected installation unit must be a professional team with the "Special Equipment Installation (Maintenance) Safety Approval Certificate" issued by the provincial quality and technical supervision department, and have the installation qualification to install the corresponding lifting capacity. After the installation unit is determined, it is necessary to assist the installation unit in handling the special equipment start-up report before the installation, and check whether the construction organization plan, installation equipment, installation procedures, technical requirements, hidden engineering acceptance records, and self-inspection reports of the installation team meet the requirements . After the installation is completed, the installation unit shall be supervised to carry out comprehensive self-inspection, operation test and load test. After confirming that the self-inspection is qualified, apply to the special equipment inspection agency for installation acceptance. It can be put into use only after it has passed the acceptance test and obtained the Safe Use License. After passing the acceptance, the user shall archive relevant technical data such as the crane's random technical data, installation data, and inspection report. Data such as regular inspections, overhauls, alterations, and accident records that occur during use will also be stored in the lifting machinery safety technology file. [2]
