Selecting the right crane is one of the earliest and most consequential decisions on a construction project. A construction crane is a machine that lifts, lowers, and moves heavy loads on a jobsite using a boom, a hoist, and rigging, and the different types of construction cranes are each built for a specific mix of load, reach, terrain, and duration. This guide breaks down the main crane types, how much each can lift, and how to match one to your project.
Key Takeaways
- Construction cranes fall into two families: static cranes that stay fixed in one spot (led by tower cranes) and mobile cranes that move around a site or drive between sites.
- Tower cranes are the primary static type for high-rise and long-duration urban builds. Maxim Crane’s tower fleet ranges from 6 to 60 tons.
- Mobile cranes include crawler, all-terrain, rough terrain, hydraulic truck, boom truck, and carry deck cranes, with Maxim capacities spanning roughly 4 tons (carry deck) to 2,535 tons (crawler).
- Crawler cranes handle the heaviest lifts, up to 2,535 tons in Maxim’s fleet, but travel on tracks and are transported disassembled, so they are not highway-legal.
- Road-legality separates the mobile types: all-terrain and hydraulic truck cranes can drive on public roads, while crawler and rough terrain cranes must be hauled to the site.
- The right crane depends on load weight, reach, ground conditions, site access, and duration. Maxim’s engineering services team evaluates these factors during project planning.
What Is a Construction Crane?
A construction crane is a machine that raises, lowers, and repositions heavy loads on a jobsite, using a boom or mast, a hoisting mechanism, and rigging to move materials that would be impossible to place by hand. The basic idea is ancient. The earliest known construction cranes appeared in ancient Greece around 700 B.C.E., and centuries of engineering have since scaled them from simple pulley systems into machines that lift thousands of tons.
Underneath that lifting power sits a system of parts working together. If you want the mechanical detail, our breakdown of the key components of a construction crane covers the mast, jib, counterweights, and hoist, and our look at the evolution of crane control systems explains the load-monitoring and sway-control technology behind safer, more precise lifts.
Static vs Mobile Cranes: The Two Main Categories
Every construction crane is either static or mobile. Static cranes are anchored in one position for the length of a job and move loads along a largely set path, trading flexibility for height, stability, and the ability to lift heavy loads to significant elevations. Mobile cranes are mounted on tracks, wheels, or a truck, so they reposition around a site or travel between sites, trading maximum height for flexibility and faster setup. The matrix below maps every crane type in this guide to one of these two categories.

The table below pairs each common crane type with its category, whether it can travel on public roads, Maxim Crane’s verified fleet capacity range, and the conditions it fits best. Capacities vary by make, model, and attachments; the ranges shown reflect Maxim Crane’s current rental fleet.
| Crane type | Category | Road-legal / transport | Maxim fleet capacity | Best-fit conditions |
|---|---|---|---|---|
| Tower crane (hammerhead, luffing jib, self-erecting) | Static | Erected on site, not road-driven | 6 to 60 tons | High-rise and vertical urban builds, long-duration jobs, tight sites where a fixed footprint works |
| Crawler crane | Mobile | Tracked; transported disassembled; not highway-legal | 30 to 2,535 tons | Heaviest lifts, soft or rough ground, energy and industrial work, long stays on one site |
| All-terrain crane | Mobile | Highway-legal and off-road capable | 88 to 818 tons | High capacity plus the need to drive between sites on public roads |
| Rough terrain crane | Mobile | Off-road only; not highway-legal | 15 to 165 tons | Confined or rough single sites, spread-out ground such as solar |
| Hydraulic truck crane | Mobile | Highway-legal | 40 to 140 tons | Frequent relocation and taxi-crane work with quick moves |
| Boom truck | Mobile | Highway-legal; quick setup | 17 to 65 tons | Lighter loads, sign and utility work, multiple jobs in a day |
| Carry deck crane | Mobile | Compact; on-site | 4 to 25 tons | Moving loads within a site, tight indoor or congested spaces |
Types of Static Construction Cranes
The tower crane is the primary static crane used in construction. It is fixed to the ground or a structure and is built to lift materials to significant heights over a long project timeline.
Tower Cranes
Tower cranes are the tall, fixed cranes most people picture on a city skyline. A tower crane is made up of a vertical mast and a horizontal jib that rotates a full 360 degrees, with a trolley that runs along the jib to position the hook. Their stability lets them lift heavy loads high, which makes them a common choice for high-rise work on tight urban sites where space is limited. Tower crane capacities vary by make, model, and configuration; Maxim Crane’s tower crane fleet ranges from 6 to 60 tons.
Tower cranes come in a few main configurations, and our guide to the primary types of tower cranes goes deeper on each:
- Hammerhead cranes: A fixed, horizontal jib in an upside-down L shape. The jib rotates but does not raise or lower. Hammerheads come in two designs: the A-frame, which uses an overhead cable structure for leverage to lift heavier loads, and the flat-top, which drops the overhead bracing for easier transport, quicker assembly, and work in height-restricted sites or where multiple cranes operate close together.
- Luffing jib cranes: Similar to a hammerhead, but the jib can be raised and lowered. That movement gives them a smaller rotation radius, which suits tight sites and jobs where several cranes work at once.
- Self-erecting cranes: The lightweight of the tower family, designed to set up and dismantle quickly. They fit tight spaces and shorter jobs but lift less than the other tower cranes.
- Level luffing cranes: The hook stays level as the jib moves up and down, keeping the load steady. This type is more common in shipbuilding and freight handling than in vertical construction.
Types of Mobile Construction Cranes
Mobile cranes move under their own power or on a carrier, which lets them reposition around a site or travel between jobs. The main mobile types are crawler, all-terrain, rough terrain, hydraulic truck, boom truck, and carry deck cranes, and they differ most in lifting capacity and whether they can legally drive on public roads.
Crawler Cranes
Crawler cranes lift the heaviest loads of any mobile crane. They ride on tracked undercarriages, similar to a tank, which spread their weight and let them cross soft, rough, or marshy ground that would trap a wheeled machine. Because they travel on tracks and are transported to the site disassembled, they are not highway-legal and tend to stay on one site for the duration of a job. Crawler capacities vary by make, model, and attachments; Maxim Crane’s crawler crane fleet ranges from 30 to 2,535 tons, which makes crawlers the primary choice for the heaviest energy and industrial lifts.
All-Terrain Cranes
All-terrain cranes combine high capacity with the ability to drive on public roads. Mounted on multi-axle wheeled carriers, they can travel between sites at highway speed and still handle uneven ground once they arrive. That flexibility makes them a strong fit when a project needs serious lifting power and the crane has to move between locations. All-terrain capacities vary by make, model, and attachments; Maxim Crane’s all-terrain crane fleet ranges from 88 to 818 tons.
Rough Terrain Cranes
Rough terrain cranes are built for difficult ground on a single site. They are more compact than crawlers and all-terrains, with large tires, all-wheel drive, and multiple steering modes that let them work on uneven or sloped ground. They are not highway-legal and must be hauled to the site, which makes them a common pick for confined jobs and spread-out sites such as solar. Rough terrain capacities vary by make, model, and attachments; Maxim Crane’s rough terrain crane fleet ranges from 15 to 165 tons.
For a closer look at how these two off-road-capable machines differ, see our comparison of rough terrain and all-terrain cranes.
Hydraulic Truck Cranes
Hydraulic truck cranes are highway-legal machines built for frequent relocation. They mount a telescoping boom on a wheeled carrier and use a hydraulic system to lift, which lets them move quickly between jobs and set up fast, work sometimes called taxi-crane service. Hydraulic truck crane capacities vary by make, model, and attachments; Maxim Crane’s hydraulic truck crane fleet ranges from 40 to 140 tons.
Boom Trucks
Boom trucks offer flexibility at a relatively low cost. Because the crane is mounted on a road-legal truck, it does not need to be hauled to the jobsite and can travel safely on public roads, which suits contractors handling lighter loads across several jobs in a day. They are a common fit for sign and utility work and for moving objects around a site on firm ground. Boom truck capacities vary by make, model, and attachments; Maxim Crane’s boom truck fleet ranges from 17 to 65 tons.
Carry Deck Cranes
Carry deck cranes are the smallest construction cranes. They pair a compact, four-wheel deck with a short boom, need little or no setup, and are built to move materials from one area to another within a site. Their low profile suits tight indoor and congested spaces where larger cranes cannot operate. Carry deck capacities vary by make, model, and attachments; Maxim Crane’s carry deck crane fleet ranges from 4 to 25 tons.
How to Choose the Right Construction Crane
Choosing the right construction crane comes down to matching the machine to the lift and the site. The main factors are the weight of the load, the reach and height required, the ground conditions, how much space the site allows, whether the crane needs to travel on public roads, and how long it will be on the job.
- Load weight and reach: The heaviest lifts point toward crawler or all-terrain cranes, while lighter, quick-turnaround work suits boom trucks and carry deck cranes.
- Ground and terrain: Soft or rough ground favors tracked crawlers or rough terrain cranes; firm, prepared ground opens up wheeled and truck-mounted options.
- Road-legality and mobility: If the crane has to move between sites, all-terrain and hydraulic truck cranes travel on public roads, while crawlers and rough terrain cranes must be hauled in.
- Site space and duration: Tight urban sites and long vertical builds favor tower cranes; confined single sites favor compact rough terrain or carry deck cranes.
These factors interact, and a lift plan often depends on details that are not obvious from load weight alone, such as ground bearing pressure, obstructions, and how the crane is assembled on site. This is where a knowledgeable lifting partner matters. Maxim Crane’s engineering services team evaluates load, reach, terrain, and site constraints as part of its project planning, and our guide to selecting the right crane covers the decision in more depth. The aim is the right equipment in the right place at the right time, matched to the job rather than forced to fit it.
Frequently Asked Questions About Construction Crane Types
What are the main types of construction cranes?
The main types of construction cranes split into two groups. Static cranes, led by tower cranes, stay fixed in one spot for the length of a project. Mobile cranes, which include crawler, all-terrain, rough terrain, hydraulic truck, boom truck, and carry deck cranes, move around a site or travel between sites.
How much weight can a construction crane lift?
It depends heavily on the type. Capacity varies by make, model, and attachments, and across Maxim Crane’s fleet it runs from about 4 tons for a carry deck crane up to 2,535 tons for the largest crawler cranes. Tower cranes fall between 6 and 60 tons, and the mobile road-legal cranes generally sit in the tens to hundreds of tons.
What is the difference between a crawler crane and an all-terrain crane?
The biggest difference is mobility. A crawler crane rides on tracks, lifts the heaviest loads, and has to be transported to the site disassembled because it cannot drive on public roads. An all-terrain crane rides on wheels, can travel on highways between sites, and handles uneven ground once it arrives, though it lifts less than the largest crawlers.
Which crane is best for building a high-rise?
Tower cranes are the usual choice for high-rise construction. Their fixed mast and rotating jib lift materials to significant heights within a compact footprint, which suits tall structures on tight urban sites where a mobile crane would not have the reach or the room.
Do you need a certified operator to run a construction crane?
Yes. Under OSHA’s Cranes and Derricks in Construction standard, employers must ensure crane operators are trained, certified or licensed, and evaluated before operating covered equipment on a construction site. These operators are part of a large skilled workforce; the U.S. Bureau of Labor Statistics counted about 539,500 construction equipment operators in 2024, a broad group that includes crane operators. That is one reason many contractors rent with a crew, since Maxim Crane’s operated and maintained rentals come with knowledgeable, professional operators.
