Mini Excavators

Unlike some of their cousins, such as Bulldozers, backhoes and graders that combine mechanical and hydraulic drive systems, all the functions of a hydraulic mini excavator are powered a hydraulic pump to create hydraulic pressure. This means that specs like pump flow rate are important as they affect the operations of the machine.

Mini-excavator terminology explained

The cab is the body of the excavator, it contains the operator’s controls, engine, hydraulic pump, fuel tank, counterweight and other components. The cab sits on top of the undercarriage or track frame, to which it connected by a swing drive.

The cab and swing drive are attached by slew rings that allow the cab to pivot to either side so that it can dig or trench parallel to the tracks.

The boom and dipper arm is attached to the cab and are actuated by multiple hydraulic rams with attachments such as buckets, augers or hammers are attached to the dipper arm with either a half hitch or a double locking quick hitch.

The advantages of a mini-excavator – independent boom swing

Independent boom swing, a feature not found on conventional excavation equipment, enables offset digging around obstacles or along obstructions such as walls. It also allows cycling in narrow situations that prevent cab rotation which reduces wear and tear on components, improves efficiency and lengthens the lifespan of your machine.

The advantages of a mini-excavator - zero tail swing

Traditionally excavators have what is termed tail swing. This is where the counterweight that is part of the cabin extends beyond the tracks. When the cab is rotated the counterweight on the rear of the cab swings in an extended arc behind the machine, potentially hitting nearby objects.

With a zero-tail swing excavator, the cab remains within the footprint of the tracks. This has two advantages, it allows the operator to focus on digging without having to worry about the rear striking something and it also enables digging in confined spaces, such as next to a wall.

The backfill blade adds extra versatility to the operations of a mini-excavator. Using a backfill blade the excavator operator can grade, level, backfill and move soil. The blade can also be used to provide extra stability while digging.

Mini excavators are relatively new solutions to an old problem – saving time and money on smaller trenching and landscaping jobs – especially retaining walls. With a blade and bucket combination and the option of accessories such as augers and hammers, a mini excavator can be a profitable change to the way you do business.

You’d be surprised at the range of people – from builders, to tradies - such as plumbers, electricians to landscapers and more – that use a mini excavator. Once you’ve replaced hours of labouring with a crowbar, pick and shovel with a mini excavator, you’ll never want to go back to hand tools again.

Most people who buy a mini excavator begin by hiring one. Then, it becomes a numbers game. With finance available for under $120 a week on some models and hire charges often exceeding that for a day, the decision to buy can be simple. With moderate use a quality mini excavator such as Sany with a long service life can pay for itself many times over.

If you or your staff have the expertise to operate a mini-excavator, dry hire may be the solution. In a dry hire you only hire the mini-excavator itself. If you don’t have the expertise or people available to operate the machine, wet hire, in which your hire the mini-excavator and an operator is the better solution.

Hire to buy mini-excavators

If you’re not sure whether to hire or buy, Ultro can provide you with a third option – rent to buy. In this situation, you can rent a Sany mini-excavator and then, when you are ready to buy, Ultro will give you a price to purchase the mini-excavator you are hiring – and they can even organise finance. The advantages of rent to buy are that you know the machine and get it immediately without interrupting your workflow.

Manufacturing and Components

A Sany mini-excavator gives you the best of both worlds – the value of being built with a low-cost Chinese manufacturing base and the quality of top-class components sourced from some of the world’s best manufacturers.

The engines are Japanese, Yanmar, world-renowned for efficiency and reliability under tough operating conditions – they are a favourite for marine applications and that’s one of the harshest environments there is.

Sany also use Kawasaki hydraulics and Italian valve components.

Efficiency and Durability

Fuel consumption is lower than competitive models, and SANY machines have an extended service life thanks to their quality components and manufacturing processes.

Power and Performance

Sany mini-excavators give you digging forces that are up to 20% higher than those of other machines, coupled with swing speeds are up to 10% faster. The result is that you finish the job faster – saving time and money.

Testing and Endurance

You can choose a Sany mini-excavator with the confidence of knowing that Sany excavators have been though 2000 hours of excavation field testing and that key components have been fatigue tested over 800,000 times.

Intelligent Control System

The independently developed intelligent control system automatically matches the hydraulic pump output to the available engine power, delivering you greater hydraulic system efficiency and lower fuel consumption.
