Concrete pump trucks aren’t one-size-fits-all. The truck that’s perfect for a backyard patio will be completely wrong for a commercial foundation, and vice versa. Choosing the right size comes down to three things: how far the concrete needs to travel, how much volume you’re placing, and what your site can physically accommodate. If you’re a contractor scheduling a pour in North Central Florida, this guide will help you match the right equipment to your job.
We run multiple boom pump and line pump configurations out of Lake Butler. The size question is one we answer on nearly every call, so here’s what you need to know.
Understanding Concrete Pump Truck Categories
Concrete pump trucks fall into two broad categories: boom pumps (truck-mounted with an articulating arm) and line pumps (trailer-mounted or truck-mounted without a boom). Within each category, sizes vary significantly. The industry generally groups them by boom length for boom trucks, and by output capacity for line pumps.
Concrete Pump Truck Size Reference
| Pump Type | Size Class | Typical Vertical Reach | Output Range | Best For |
|---|---|---|---|---|
| Line Pump (Trailer) | Small / Compact | Ground-level (horizontal runs up to 300+ ft) | 15-30 yd3/hr | Residential patios, driveways, backyard pours, grout, fill |
| Line Pump (Truck-Mounted) | Mid-Size | Ground-level (longer horizontal capability) | 25-50 yd3/hr | Larger residential, light commercial, long-distance horizontal runs |
| Boom Pump | Small (under 90 ft reach) | Up to ~85 ft vertical | 80-130 yd3/hr | Residential foundations, pool decks, tight commercial sites |
| Boom Pump | Mid-Size (90-120 ft reach) | Up to ~115 ft vertical | 100-170 yd3/hr | Commercial foundations, tilt-wall, elevated pours, multi-story |
| Boom Pump | Large (120+ ft reach) | 120+ ft vertical | 150-200+ yd3/hr | High-rise, large-scale commercial, infrastructure |
Note: Reach figures are approximate and vary by manufacturer, boom configuration (Z-fold vs. roll-fold), and setup conditions. Actual reach on your site depends on truck placement relative to the pour area.
Small Concrete Pump Trucks: When Less Is More
Small concrete pump trucks include trailer-mounted line pumps and compact boom pumps. These machines are the workhorse of residential concrete work.
Trailer-Mounted Line Pumps
A trailer pump is the smallest and most portable option. It gets towed to the job site, connects to the ready-mix truck’s chute, and pushes concrete through a hose that the crew lays along the ground. No boom arm, no outriggers, minimal footprint.
Line pumps are ideal when you’re pouring under 20 cubic yards, the site has tight access (narrow lots, backyard gates, interior spaces), and the concrete only needs to travel at ground level. They also handle grout and specialty mixes that larger boom pumps can’t.
The tradeoff is speed. A line pump might move 15-30 yards per hour, which is fine for a driveway or patio but painfully slow on a 50-yard foundation.
Small Boom Pumps (Under 90 ft)
A small boom pump gives you the reach and speed of a boom in a more compact package. These trucks fit on residential streets and can set up in tighter spaces than their bigger counterparts. For a mid-size residential foundation or a pool deck that’s blocked by the house, a small boom pump is often the sweet spot: enough reach to clear the obstacles, enough output to keep the pour moving, and small enough to fit the site.
Big Concrete Pump Trucks: Built for Volume and Reach
When contractors talk about a “big concrete pump truck,” they’re usually talking about a 39-meter boom pump. These are the machines you see on commercial job sites, highway projects, and multi-story construction.
Mid-Size Boom Pumps (90-120 ft)
This is the most versatile class of boom pump for commercial work. A 100+ foot boom can reach across a full commercial building footprint, over retention walls, and into areas that would require hundreds of feet of ground hose with a line pump. Output rates are high enough to keep multiple ready-mix trucks cycling through without bottlenecks.
For most commercial foundations, tilt-wall pours, and elevated deck work in the North Florida market, a mid-size boom pump is the right tool. It balances reach, output, and maneuverability for the types of jobs contractors run in this region.
Large Boom Pumps (120+ ft)
The biggest boom pumps on the market reach well over 150 feet vertically and can pump 200+ cubic yards per hour. These are specialized machines for high-rise construction, massive commercial pours, and infrastructure projects like bridge decks and retaining walls.
Most residential and mid-size commercial work in North Central Florida doesn’t require this class of equipment. But when you need it, nothing else will do the job.
How to Choose the Right Size for Your Project
Picking the right pump size isn’t about getting the biggest truck available. It’s about matching the equipment to the job. Here’s how to think through it.
Start with Volume
How many cubic yards are you placing? For anything under 15 yards, a line pump is usually the right call. Between 15-30 yards, either a line pump or a small boom could work depending on access. Over 30 yards, a boom pump’s speed advantage starts saving you real money on labor and truck standby time.
Map Your Reach Requirements
Measure the distance from where the pump truck can realistically park to the farthest point of your pour. Don’t forget vertical distance if you’re going up. Add 10-15% buffer because the boom doesn’t reach its maximum in every direction from every setup point. If the pump needs to reach 80 feet and the boom is rated for 85, you’re cutting it dangerously close.
Check Site Access and Ground Conditions
Bigger boom trucks need more room. A large boom pump with full outrigger spread can require 30+ feet of width on stable ground. Florida’s sandy soils can be a problem, especially after rain. If the ground is soft, you may need timber mats under the outriggers, or you may need to downsize to a lighter truck.
Overhead power lines are another common issue on Florida job sites. The boom operator needs clearance above and around the boom’s full swing path. If lines are in the way, you may need a shorter boom that can work under them, or a line pump that stays at ground level entirely.
Factor In Your Schedule
In Florida’s summer, afternoon thunderstorms are a daily reality. If your weather window is tight, a bigger, faster pump can be the difference between finishing the pour and losing half of it to rain. For a detailed comparison of boom vs. line pump tradeoffs, see our boom pump vs line pump guide.
Common Sizing Mistakes Contractors Make
Going too small to save money. A line pump on a 40-yard pour will cost less per hour, but the pour takes three times as long. Your finisher crew is on the clock the entire time. Your ready-mix trucks are waiting in line. The “savings” on pump cost get eaten by labor and standby charges.
Going too big for the site. A 120-foot boom on a residential backyard pour is overkill. You’re paying a premium hourly rate for reach you don’t need, and the truck might not even fit the lot. Plus, bigger trucks need more setup time.
Forgetting about outrigger space. Contractors measure the distance to the pour but forget to check whether the truck has room to deploy outriggers. If the pump can’t set up safely, it can’t pump. Check this before pour day, not the morning of.
Ignoring ground conditions. A fully loaded boom pump truck can weigh 60,000+ pounds. On rain-soaked Florida sand, that weight matters. If you haven’t verified the ground can support the truck and outriggers, you’re gambling.

Frequently Asked Questions
What sizes do concrete pump trucks come in?
Concrete pump trucks range from compact trailer-mounted line pumps (no boom, ground-level pumping) to small boom pumps with under 90 feet of reach, mid-size boom pumps in the 90-120 foot range, and large boom pumps exceeding 120 feet. Line pumps are best for small residential pours and tight access. Boom pumps scale up for commercial, elevated, and high-volume work.
How do I choose the right size concrete pump truck?
Start with three factors: how many cubic yards you’re placing, how far the concrete needs to travel (including vertical distance), and what your site can accommodate. Under 15 yards with ground-level access usually calls for a line pump. Over 30 yards or any pour with obstacles typically needs a boom pump. When in doubt, describe your project to your pump operator and let them recommend the right equipment.
What is the reach of different boom pump sizes?
Small boom pumps typically reach up to about 85 feet vertically. Mid-size booms reach roughly 90-120 feet. Large boom pumps can exceed 150 feet of vertical reach. Actual reach on site depends on the truck’s setup position, boom configuration, and how far the boom needs to extend horizontally vs. vertically. Always add a buffer beyond your minimum reach requirement when selecting equipment.
