Crawler Crane

A crawler crane is a type of crane mounted on an undercarriage with a set of tracks, which are also known as crawlers. As a self-propelled crane, it is able to move around a construction site, with the tracks providing excellent traction in even the harshest working conditions. The user of crawler cranes has increased recently because of the improved sophistication of modern Hydraulic drive systems, which allow for greater control.


There are many different manufacturers of crawler cranes, including American Crane, Hitachi, Lampson, and Terex. Some of the most popular models include the Sumitomo C52, the Mantis 2010 10-ton Hydraulic, and the 2003 Manitowoc 555 Series II. The first crawler crane was manufactured by Northwest Engineering in the 1920s, while the world’s first “All Hydraulic” crawler crane was created by HYMAC LIMITED.

Crawler cranes, similar to a crawler tractor, travel on crawler tracks. They typically come with either a lattice boom, that has to be manually assembled, or a telescopic arm, which extends with the use of hydraulics. People who wish to operate a crawler crane must first be certified to operate a crane. This typically comes from OSHA (Occupational Safety and Health Administration), which oversees proper crane construction and safety. Typically, the foot pedals control the pressure being generated by the main pump and the joysticks control the movements of the boom, both forwards and backwards and left and right.

Safety Features & Guidelines

Like all cranes, crawler cranes are fitted with multiple safety features that help contribute to a safer work environment. For example, to reduce the risk of electrocution when a crane clips a power line, crawler cranes are equipped with anti-current devices. To prevent upset, they are fitted with counterweights and anti-upset devices. Hundreds of people are hospitalized each year as victims of crane-related accidents, however, so safety features are not enough. It is important to follow several safety steps when operating a crane or working on a job site with a crane. This includes making sure all of the crane’s parts are well maintained, and that the area where the crane is working is clear of potential obstacles and hazards. You should also have someone on the ground who can communicate with the crane operator, who may not have great visibility while operating the crane.

Pros & Cons

Crawler cranes have both advantages and disadvantages when compared to your typical crane. The biggest advantage crawler cranes have is how easily they can move around a job site because of their tracks.

The crane is stable on its tracks, so it can also travel with a load. This makes moving materials around a job site even easier. The biggest disadvantage is that it is extremely heavy, and while it can move easily around a job site, it can be difficult to move between multiple job sites. They usually have to be disassembled and moved by trucks or ships to its next location. This can be very inconvenient and costly if the crawler is required at multiple job sites, and can reduce efficiency.
