Compact Application Tips: When bigger isn’t better

January 07, 2007 |

Contractors quickly realized the value of using smaller sized machinery when working between buildings and incorporated compact excavators into their fleet. They’re such popular pieces of equipment, contractors are using these machines on all types of jobsites. Realizing their adaptability, manufacturers are adding options like long- or extendable-arm configurations and multiple attachments to make the compact excavator useful for even more applications.

Thinking small can cut costs
It’s undeniable the compact excavator’s major attraction is its small footprint – in fact, many models offer a retractable undercarriage and zero-tail or -house swing. But fitting in tight quarters isn’t the machine’s only advantage. Tom Connor, Bobcat compact excavator product specialist, says to consider the cost savings. “Compact excavators are alluring to many contractors because smaller, lighter equipment is easier and less expensive to transport,” Connor says. “It also uses less fuel.” And the tracked undercarriage minimizes damage to finished surfaces, saving you from costly repairs once the job is done, he says.

For some applications, adding a compact excavator to your fleet will decrease the need for subbing out some aspects of the job, Connor says. “Minimizing reliance on a third party makes for more effective scheduling,” he says.

Routine maintenance on compact excavators is also simple, reducing downtime. Mike Ross, national product and training manager, Takeuchi, says several features make servicing the machine fast and easy. “Four of our models, for example, are equipped with a tilt-up operator’s platform to allow quick access to the valves, pumps and engines,” he says. “All of our excavators have a remote slew lubricating system, an automatic fuel bleed system, conveniently located hydraulic pressure test ports and easy access to the battery.”

Connor says Bobcat excavators have engine checkpoints that are both easy to find and reach, as well as a swing-open tailgate and side access hood to allow the operator to easily reach components. “Easily performing routine maintenance ensures operators maintain regular uptime and avoid service breakdowns,” he says.

Don’t let the new features lull your operators into a false sense of security, though – just because maintaining your compact excavator has been made easier, taking appropriate safety precautions is vital.

How small is too small?
The smaller the excavator, the bigger the tradeoff with respect to dig depth, reach, dump height and breakout force. In reality, if you need to dig much deeper than 10 feet, you’ll have to use a larger machine. In response to this limitation, manufacturers have taken a cue from backhoes and started to compensate with extended-arm configuration packages, which can extend maximum depth and reach by about a foot.

When choosing a compact excavator, think about your future business growth along with your present needs, says Bill Anderson, compact excavator product specialist, Volvo. “When an excavator can perform 85 percent or more of the work required, you have chosen the correct size,” Anderson says. “When considering future business growth, you may want to consider going one class size bigger than you presently need.”
