Are you looking for an excavator that can get close to structures, traffic without the worry of a large counterweight?
Tight job sites present unique challenges. In order to be the most productive in those instances you have to carefully consider the type of equipment to use. For instance, an excavator with a large counterweight could swing into an obstruction or into a lane of traffic.
“Tight-tail-swing and compact excavators continue to gain popularity because they are a great solution for these kinds of sites,” said Jonathan Tolomeo, Komatsu Product Manager. “On projects where space is at a premium, such as urban areas or during highway reconstruction where you can only work in a single lane, they deliver outstanding production results in a small package. They are also great for tasks that require you to place the machine very close to a house or other type of building.”
Tolomeo added that not all tight-tail-swing and compact excavators are right for every limited-space situation. Take foundation repair for example. He emphasized that the best fit for the job is a machine with a swing boom that can work independently of the cab.
“The operator positions the tracks very close to the structure, then only moves the boom,” Tolomeo explained. “This allows for digging at various angles while the cab stays in a fixed position. There is virtually no chance of a counterweight swinging into the house or other building as you dig and pile dirt.”
Attachments increase versatility
Komatsu recently introduced its latest model, the PC88MR-11, with a host of new features that improve production and fuel efficiency with a viscous fan clutch.
“An improved design of the standard blade rolls material better for more efficient dozing or backfill work, which increases the PC88MR-11’s versatility and may provide costs savings by not having to use an additional machine,” said Tolomeo. “You can further increase versatility with attachments such as hammers and grapples.
The excavator has two-way auxiliary control with a dual-stage relief valve, as well as a thumb mounting bracket – so it will run practically any tool in the industry. That capability increases its availability and gives you additional applications and potentially better profitability and return on investment.”
He added that productivity increases when you can set hydraulic pressure and flow from inside. The PC88MR-11 lets operators do that, which is a change from the previous model. Additional upgrades include better serviceability with larger service doors and centralized ground-level access to filters located within a common area.
“The list of enhancements, improvements and upgrades is long, and we encourage anyone who is looking for a productive compact excavator that increases versatility, to contact their distributor for a comprehensive list and a demonstration,” said Tolomeo.
