Each construction job is different and has unique requirements to fulfill. There are a variety of different cranes available—each suited for different tasks. Crawler cranes are great for use in projects where there is rough or uneven terrain. By choosing the correct crane to fit the task, the job can get done as smoothly as possible. It is important to choose the right crane for the situation. When the project requires the lifting of heavy loads on uneven surfaces, the right crane just might be a crawler crane.
What is a Crawler Crane?
These unique cranes get their names from the tracks or crawlers that they are mounted on. These tracks provide stability and mobility for the crane and do not require the use of outriggers. This makes it so that the crane can be set up in a smaller area while also having the benefit of stability. Since the tracks spread the weight around, they can be used on softer surfaces without sinking. They can also move about the site carrying a load.
What are the parts of a Crawler Crane?
Cranes have several different parts. The part that makes them most unique are the crawlers that allow the crane to move on rough or uneven ground and provide stability without the use of outriggers. While the other parts of the crane are similar to other cranes, they are able to carry large loads that some other cranes might not be able to lift or move. Some of the parts of the crane include:
- Boom. The lifting component of the crane, usually has a lattice construction.
- Carbody. The part of the machine that connects the rotating bed to the crawler assemblies.
- Crawlers. The tracks that the crane is mounted on, and operate as the wheels of the crane.
- Jib. The operating arm of the crane that moves horizontally to move loads.
- Hoist. The machinery unit used to lift and lower the load.
- Operator’s Cab. The fully enclosed and insulated compartment that holds the operating apparatus.
- Sheaves. Pulleys with a grooved wheel for holding the wire ropes.
- Wire Ropes. Cables made of several strands of wire twisted together and used to hoist loads in cranes.
What are the benefits of Crawler Cranes?
There are many benefits to using a these amazing cranes. Some include:
- Mobility. Crawlers can move around the site easily. They are able to move across rough and uneven terrain. Since the crawlers distribute the weight, they can even cross soft ground. They do not need outriggers to stabilize them so they are easier to move about the site.
- Stability. The large crawlers that the crane sits on make them very stable. Most cranes require outriggers to keep them stable. These outriggers require more room for set up. Since crawler cranes have stability without the use of outriggers, it allows them to be more flexible on the job site.
- Carrying Large Loads. These cranes can lift and move large loads, making them ideal for construction jobs where large loads will need to be lifted or hauled. They can also move while lifting the load which makes them ideal for transporting large loads across a job site.
How are They Moved Between Sites?
One drawback to crawler cranes is their size, which makes them more difficult to move between sites. The crawlers are excellent for rough terrain, but cannot be driven on regular roads. Crawlers must be dismantled and driven to a new site in trucks. WM Services specializes in getting the right crane to the job site. With our extensive experience, we can make arrangements for the crane to get to the job without hassle.
