Supervise all complex or unusual lifting operations. Class is determined by the selected lifting system (for example, class Hfor a bridge crane, class Hfor a fork-lift truck on an uneven ground). The dynamic factor depends on the means used for the lifting. The Crane Lift Plan may be valid for more than one day, as long as the configuration , location, and parameters used for developing “worst case” condition have not changed.
Use multiple lift plans for multiple locations. All rigging devices MUST bear the name of the manufacturer and identify WLL and be certified as to their capacity.
Enter a title, description and customer name for your lift plan. Select the layout format and resolution you want for your lift plan. Application requirements - to reduce headroom, provide multiple lifting points, to provide adjustable lifting centres, to handle out of balance loads, to remove or control inward or crushing forces, to allow for special load attachments. FROM CHART - RATED CAPACITY OF CRANE THIS LIFT 5. The lifting of objects generally occurs on construction sites, in factories and other industrial situations. Correct lifting can move large objects efficiently and reduce manual handling operations.
Incorrect lifting however, can lead to disastrous accidents. Every year, incorrect lifting procedures cause injuries, loss of work time and property.
A critical lift is defined as any non- routine crane lift requiring detailed planning and additional or unusual safety precauti ons. Understand moment of force considerations as the relate to the movement of stationary objects. Explain the concept of elasticity of solids. This lifting plan sample also provides calculation for sling tension.
Additionally you shall be able to select the suitable lifting gear in accordance with the safe working load and weather conditions etc. How to calculate reps and sets for weight lifting? What is crane lifting plan? When do you need a lift plan? The Premier Construction Engineering Firm in the NYC Metro Area Professional, Capable, and Dedicated.
Calculations to be made will include the capacity, both of the overall beam and of the loading of the individual lifting points. The officer responded to the question by saying that it was an emergency. It is your responsibility to assure that the slings you use are appropriate for your application. Description of lift: NB reduction in load capability if man basket is used.
Date of lift: Time of lift: Monetary value of load: Details of Cranes. Heavy lifting is a high risk operation that must be planned and executed properly. This technical note aims at preventing lifting failures caused by supporting ground not being firm enough, highlighting the importance of having a proper lifting plan and a correct estimate of the applied bearing pressure induced by different types of crane.
The lift plan required a rigging sketch or photographs that include information that needed to calculate the forces on all of the rigging gear used in the lifting activity. Crane Weight The maximum weight of the crane to be used 5000kgs (worst case scenario) 2.
Load The maximum load to be lifted 2000kgs 3. Ground Type Ground comes in granular and cohesive types. Overall responsibility and control of the lifting operation. Ensuring the lift is undertaken in accordance with the lift plan. Pre-Lift Review A pre-lift meeting involving the participating personnel (i.e. crane operator, lift supervisor, rigger) should be conducted prior to making a critical lift.
The critical lift plan should be reviewed to ensure that the project team is prepared to safely conduct the lift. Any lifting gear which fails during an operation must not be moved until an investigation has been carried out. This does not apply in emergency situations. Using materials that are already available will cut down on costs and allow for more money to be put into a higher quality hoist. You need to have a lift plan undertaken, You as a rule should not exceed of the lifting capacity of the mobile crane.
A complete lift plan will also take you ground point loading into consideration.
