Types of Cranes and Their Uses: How to Choose by Site
Choose the crane type by your site: ground, access, height, number of lifts and indoor or outdoor work. Then confirm the load and reach on the load chart.
Choose a crane by the heaviest lift at its widest radius, not by load weight alone. These guides explain the main crane types (mobile, crawler, tower and spider) and where each fits, how to read a load chart, what a lift plan contains, and how ground conditions change the setup. They also cover rigging gear, signalling, and boom trucks for lighter lifts. Read the guide on crane types first, then the load chart and lift plan guides before you ask suppliers for quotes.

A crane's tonnage is only its best case. The load chart shows what it can lift at your radius, boom length and set-up, once the rigging is deducted.
Do not ask for a tonnage. Work out the load with rigging, the radius at pick and at set, the hook height and the ground, then ask suppliers to propose a crane that fits.
Choose by the weight and reach of the lift, not by the name. A light load, short reach and material that must travel with the machine suit a boom truck; heavier, higher or longer lifts suit a mobile crane.
Choose by four site facts: the ground, how often the crane must move, how long it stays, and how it gets to site and is assembled.
Count the lifts you need each month, how heavy and how high they are, and for how many months. Many repeated lifts favour a tower crane; a few heavy ones favour mobile cranes.
Settle the load, radius, ground and crew before the crane is booked, confirm papers before it leaves the yard, and give every item a named owner.
A rigging set can lift no more than its weakest part, and sling angle and hitch type change what that is. Read every tag and stop at any damage.
Six steps from lift data to a booked crane: ask every supplier to quote the same scope, then compare capacity at your radius, crew, certificates and hire terms.
