If you’re an on-site machinist looking to get work in the construction and mining industries, you’ll need to understand the basic types of plant used in this lucrative sector. From bulldozers backhoe loaders, getting familiar with each vehicle type will help to avoid potential embarrassment when talking to potential customers. More importantly it will open your eyes to new opportunities for in situ machining.
The nine examples explained below don’t represent a complete list of every conceivable construction vehicle variant. What we’ve included are the main categories most likely to need in-situ machining when undergoing maintenance. Most seem obvious from the name, but a few need a little explanation.
A digger or shovel mounted on a truck. These vary from the very small models used for garden landscaping to the huge type used in quarries. Having quite a few hinges on the arms and the bucket, these are strong candidates for line boring services.
A loader's main purpose is for scooping up things like earth or gravel using the large 'bucket' at the front which pivots, allowing the contents to be emptied elsewhere.
This combines both of the above by including a loader on the front and an excavator on the back.
The bulldozer’s main purpose is to push large amounts of dirt, rock or other materials around a work site. To perform this, the bulldozer is fitted with a blade or shallow bucket lowered to the ground and used to scrape the material to be moved. Bulldozers for construction normally run on tracks which provide more traction than those using wheels. Some lifting of the front blade or bucket can be carried out, but not to the extent of a loader.
Other names are telehandler, teleporter and boom lift. These are similar to a forklift, but include a boom, Telescopic handlers are widely used in the agriculture and construction industry. Most are fitted with pallet forks but other attachments are available.
Also known as a dumper or tipper truck, these are used for transporting loose material. A typical dump truck operates on wheels rather than tracks, and is equipped with an open-box bed, hinged at the rear and with hydraulic rams for lifting.
These huge machines are used for civil engineering and surface mining. They operate on tracks using a suspended bucket which is dragged across the ground to gather large amounts of aggregates and earth.
You know what they do. The opportunity for machining here is not so much line boring, but on the crane pedestal surface needs which when worn needs machining with an orbital milling machine.
The name says it all. As with the telescopic handler, these use telescoping booms that can be extended outwards – just like the sections of an optical telescope.
Construction vehicles have a tough time and need to withstand a great deal of stress and rough treatment. Wherever there’s a pivot point, the likelihood is it will wear out at some point. Maintenance can be carried out on-site using a line boring machine like this one.
The usual refurbishment process is to machine the worn section in the hinge pin or bucket, add a metal collar by shrink fitting, and then machine the collar’s internal diameter back to manufacturer’s specification.
