Built for the People Who Build the World
Every skyscraper, every highway, every bridge starts with heavy equipment — and the people who keep those machines running. We provide the service manuals they depend on.
Born on the Jobsite
It started with a broken hydraulic pump on a CAT 320 excavator and a service manual that cost more than the repair itself. Our founder, a heavy equipment mechanic with 15 years of field experience, knew there had to be a better way.
In 2014, Construction Manuals was born with a simple mission: give every mechanic, contractor, and fleet manager instant access to the same factory-level service documentation that authorized dealers use — at a fraction of the cost.
Today, we serve over 50,000 professionals across 120+ countries. From a single excavator operator in rural Australia to a fleet of 200 cranes in Dubai, our manuals keep the world's heavy equipment running.
