A Beginner's Guide to Crane Lift Plans
A successful crane lift starts before the crane arrives. A plain-language walkthrough of lift planning: load information, pick and set locations, radius, ground, rigging, and communication.
A successful crane lift starts before the crane arrives.
A lift plan takes the information about the load, jobsite, equipment, and lifting operation and turns it into a practical strategy for getting the load from one location to another.
For someone planning their first crane project, the process can seem complicated.
But a basic lift plan comes down to answering a few important questions: What are we lifting? Where is it? Where does it need to go? Where will the crane sit? And can the crane safely perform the lift from that location?
Start With the Load
The first step is understanding exactly what needs to be lifted.
That means more than knowing the general description of the item.
A lift plan should identify information such as:
- Weight
- Dimensions
- Center of gravity
- Pick points
- Rigging requirements
- Final placement
Accurate weight information is particularly important because it affects crane selection and capacity.
If the weight is incorrect, the rest of the lift plan can be based on incorrect information.
Whenever possible, use verified information from the manufacturer, shipping documents, equipment specifications, or another reliable source.
Identify the Pick and Set Locations
Next, determine where the load starts and where it needs to end up.
The crane needs to be positioned so that it can reach both the pick location and the final placement area while maintaining the required capacity.
For example, a rooftop lift may involve picking a piece of equipment from a delivery truck and placing it on a specific area of a building.
The crane setup location has to work for both parts of that operation.
Knowing the beginning and ending points gives the crane provider the information needed to start evaluating the required reach and equipment.
Calculate the Required Radius
One of the most important measurements in a crane lift is the working radius.
This is the horizontal distance from the crane's center of rotation to the load.
As the radius increases, available crane capacity generally decreases.
That means the distance between the crane and the load can be just as important as the load's weight.
A load may be relatively easy to lift when the crane is positioned close to it. If the crane has to move farther away because of a building, property restriction, road, or other obstacle, the required crane capacity may change.
The setup location should therefore be considered before choosing the crane.
Evaluate the Ground
Once the setup location has been identified, the ground needs to be evaluated.
A crane requires a suitable surface for the planned operation. Ground conditions can include firmness, compaction, drainage, slope, and potential underground hazards.
The crane setup area also needs to meet applicable requirements and manufacturer specifications.
Do not assume that a paved or apparently solid surface automatically answers every question.
There may be underground utilities, tanks, voids, vaults, recently disturbed soil, or other conditions beneath the setup area.
These issues are much easier to address before the crane arrives.
Plan the Rigging
The crane is only one part of the lifting system.
The load also needs to be properly connected to the crane.
Rigging selection should take into account the load's weight, dimensions, shape, center of gravity, lifting points, and intended lifting configuration.
The rigging equipment itself also contributes to the total load being handled.
The goal is to establish how the load will be supported and controlled throughout the lift before the operation begins.
This is particularly important for loads that are irregularly shaped, have an unusual center of gravity, or require specialized lifting points.
Establish Communication
Everyone involved in the lift needs to understand how communication will work.
The crane operator may not be able to see the entire load path from the cab.
That makes communication between the operator, signal person, riggers, and other site personnel an essential part of the operation.
Before the lift begins, the team should know who is directing the lift and what communication method will be used.
Clear communication reduces confusion and helps everyone understand when the crane is moving, stopping, lifting, lowering, or repositioning.
Think About the Entire Operation
A lift plan should not focus only on the moment when the load is in the air.
Consider what happens before and after the pick.
- How will the crane enter the site?
- Where will it set up?
- How will the load arrive?
- Will other equipment or vehicles need to be moved?
- Is the landing area ready?
- Are there overhead obstructions?
- Will traffic control or permits be required?
- Is the receiving crew ready when the crane arrives?
These details can determine whether a lift proceeds smoothly or ends up waiting on another part of the jobsite.
A Simple Lift Plan Checklist
For a basic crane project, your plan should be able to answer these questions:
- What are we lifting?
- How much does it weigh?
- What are its dimensions and lifting points?
- Where is the load being picked up?
- Where does it need to be placed?
- How far does the crane need to reach?
- Where will the crane sit?
- Can the ground support the setup?
- How will the load be rigged?
- How will the crew communicate?
If those questions have clear answers, the crane provider has a much better understanding of what the project requires.
Why Lift Planning Matters
A lift plan is not about creating unnecessary paperwork.
It is about identifying the important details before they become problems.
The earlier the load, crane setup, radius, ground conditions, rigging, access, and communication requirements are understood, the easier it is to select the right equipment and prepare the jobsite.
Good planning also gives the project team an opportunity to identify questions before the crane arrives.
That is valuable because a problem discovered during planning can usually be solved more easily than a problem discovered after the crane is already mobilized.
Planning Your First Crane Lift?
You do not need to know everything about cranes before starting the conversation.
Provide Advanced Crane with the load information, site details, pickup and landing locations, and target date.
Our team can help identify the crane and planning requirements for the lift so the jobsite is ready when the crane arrives.
