How to Choose the Right Crane for Your Project

The crane is often the backbone of construction and industrial projects. Selecting the wrong one can increase costs and risk. This guide helps you choose a crane based on capacity, height, reach, and site conditions.

Key Factors Before Renting

1) Required lifting capacity

Know the heaviest load you will lift. Always maintain a safety margin and verify the load chart for the given radius and height.

2) Working dimensions

• Lift height: maximum height to place the load.
• Radius: horizontal distance from crane center to load position.

3) Ground conditions

Flat/compacted surfaces favor mobile cranes, while crawler cranes excel on uneven or soft ground due to better weight distribution.

Common Crane Types

Mobile Cranes

Versatile and quick to mobilize. Ideal for short-term jobs and urban sites.

Crawler Cranes

High capacity and excellent stability on rough terrain. Best for long-term heavy lifts.

Rough-Terrain Cranes

Four-wheel drive and large tires for access to challenging sites away from paved roads.

Safety First

• Use certified, experienced operators.
• Perform scheduled inspections and maintenance.
• Comply with manufacturer instructions and lift plans.
• Conduct a job-site risk assessment before lifting.

Survey the site before you sign

A site visit before the contract is the step that separates a smooth lift from an expensive surprise. It confirms the crane can physically reach the site, establishes where it will stand, and verifies the ground will carry the machine and the load together. Access gates, turning radius, overhead lines and the position of the nearest hard standing all change which machine is the right answer — and all of them are cheaper to discover a week early than on delivery morning.

What a load chart actually tells you

The tonnage in a crane's name is its maximum capacity at minimum radius — the best case, not the working case. The load chart is the real specification: it lists what the machine can lift at each combination of boom length and radius, and the figures fall away sharply as the load moves out. A 100-tonne crane working at 30 metres is not a 100-tonne crane. Before committing, check the chart at the radius and the height your job actually needs, with the rigging weight included in the load.

Planning the lift

1. Weigh the load properly — including slings, spreader beam and shackles, which are routinely forgotten.
2. Fix the radius — the horizontal distance from the crane's centre of rotation to the set-down point, not to the edge of the building.
3. Add the height — building height plus load height plus sling length plus clearance.
4. Check the ground — level, compacted, and matted under the outriggers where the bearing pressure concentrates.
5. Confirm the approach — that the machine, and the transport carrying it, can reach the standing position at all.

When a boom truck is the better answer

Not every lift needs a crane. Inside a city, where access is tight and the load is moderate, a boom truck often finishes the job faster: it drives in, lifts, sets the load on its own bed and leaves, with none of the set-up and rigging time a mobile crane needs. Reserve the crane for the loads and the heights a boom truck genuinely cannot reach — the equipment budget goes further that way.

Frequently asked questions

What capacity crane do I need?

It depends on the load weight and the working radius together, never the weight alone. Send us the load, the distance from where the crane can stand to where the load must land, and the lift height, and we will identify the class of machine from the load chart.

Do you supply the operator and the rigging?

Yes. Certified operators are available with the machine, and lift plans are reviewed before execution. Rigging requirements are agreed as part of the quotation so nothing arrives missing.

Can a crane work on unprepared ground?

A wheeled crane needs level, compacted ground and load-spreading mats. For genuinely rough or soft terrain, a rough-terrain machine is the right choice — which is one of the things a site survey settles before delivery.
