How to Plan a Crane Lift
A crane may spend only a few minutes actually moving a load, but a successful lift starts well before the hook leaves the ground.
Load weight, crane position, reach, site access, ground conditions, rigging, overhead hazards, and final placement can all affect how a lift is performed.
D&O Crane provides crane rental services throughout Arizona for commercial construction, industrial work, equipment placement, infrastructure projects, and specialty lifts.
Providing accurate information before scheduling crane service helps our team determine what equipment is appropriate for the job.
Know What You Are Lifting
The first step is identifying the load.
Knowing that something is a generator, HVAC unit, tank, or piece of machinery is not enough. The crane operator needs an accurate weight and information about the load’s dimensions.
Useful information includes:
- Total load weight
- Length, width, and height
- Manufacturer and model
- Available lifting points
- Center of gravity
- Rigging requirements
- Pickup location
- Final placement location
Manufacturer specifications, equipment drawings, shipping documents, and identification plates can help confirm this information.
Do not guess the weight of a load when accurate specifications are available.
Understand Crane Reach
One of the most common misunderstandings about crane capacity involves reach.
A crane’s rated tonnage does not mean it can lift that weight at every distance from the machine.
As the distance between the crane and load increases, lifting capacity changes. Boom length, boom angle, configuration, and operating radius all affect the crane’s available capacity.
For example, placing equipment directly beside a crane may require significantly less capacity than placing the same equipment on the opposite side of a building.
This is why D&O Crane needs to know both where the crane can set up and where the load needs to go.
Our fleet includes cranes ranging from 8 tons to 175 tons, allowing our team to match equipment to a wide range of lifting requirements.
Check Site Access Before the Crane Arrives
The crane has to reach the setup location before the lift can happen.
Site access should be reviewed for gates, narrow roads, turns, slopes, parked vehicles, construction materials, buildings, and other obstacles.
A site that is easy to reach with a pickup truck may not provide enough room for a large crane.
Contractors should also consider whether other crews or deliveries will block access on the scheduled lift day.
Photos of the site can help with initial planning. For more complicated lifts, additional site information or an onsite review may be needed before the crane is dispatched.
Evaluate the Setup Area and Ground Conditions
Once the crane reaches the site, it needs a suitable location to set up.
Mobile cranes use outriggers or other support systems to create a stable operating base. The setup area must provide enough space for the crane and its required configuration.
Ground conditions also matter.
Soft soil, recently excavated areas, underground utilities, septic systems, vaults, trenches, and other conditions can affect whether the ground can safely support the equipment.
Sloped or uneven terrain may create additional challenges.
These conditions should be identified before crane setup begins. Finding an unknown underground structure after the crane arrives can delay the job or require the lift plan to change.
Identify Overhead and Surrounding Hazards
Crane operations require enough room for the boom, load, rigging, and supporting equipment to operate safely.
Potential hazards include:
- Power lines
- Buildings
- Trees
- Communication lines
- Light poles
- Construction equipment
- Traffic
- Other cranes
- Workers in surrounding areas
Power lines require particular attention because contact or close proximity can create serious electrical hazards.
The Occupational Safety and Health Administration establishes requirements for cranes and derricks used in construction, including provisions for power line safety, equipment setup, inspections, and qualified personnel.
Identifying hazards before lift day gives the crew more time to determine how they will affect crane placement and operations.
Plan the Rigging
The crane is only one part of the lifting system.
Slings, shackles, spreader bars, lifting beams, and other rigging equipment may be needed to connect and control the load.
Rigging requirements depend on the equipment being lifted, available lifting points, load geometry, weight, and center of gravity.
Some loads are relatively straightforward. Others require careful planning to keep the equipment level and controlled during the lift.
D&O Crane provides rigging and labor services for projects requiring additional equipment handling and placement support.
Coordinate Transportation and Lifting
Some projects require heavy equipment or machinery to be transported before it can be lifted into position.
Coordinating transportation and crane scheduling is important because delays in one part of the project can leave equipment, trailers, or crews waiting onsite.
D&O Crane provides heavy haul transportation services for machinery, construction equipment, industrial components, and oversized loads.
When crane and heavy haul services are required for the same project, coordinating both through D&O Crane can simplify scheduling from pickup through final placement.
Provide Information Before Lift Day
The more information available before the crane arrives, the easier it is to prepare for the job.
When requesting crane service, provide:
- Load weight and dimensions
- Equipment specifications
- Pickup location
- Placement location
- Estimated reach
- Required lift height
- Site photos
- Access information
- Ground conditions
- Known overhead hazards
- Rigging requirements
Complex lifts may require additional planning.
D&O Crane also provides training and inspection services for contractors and equipment owners who operate cranes and lifting equipment.
Schedule Your Crane Lift With D&O Crane
Good lift planning can reduce delays, improve coordination, and help crews identify potential problems before equipment reaches the jobsite.
If you are unsure what crane your project requires, start with the load information and jobsite details. Our team can use that information to determine what equipment may be appropriate for the lift.
