How to buy - Excavators
Safety, performance and productivity are key considerations when choosing a machine, says Sally Drury.
Q: What size excavator should I be using?
A: Excavators come in all sizes - micros, minis, midis, compacts and larger. Landscapers looking to hire or purchase one will find there is a wide range of models to tackle a variety of jobs. For safety, performance and, crucially, productivity, it is important to choose the right machine for the task and the site.
The type of work and volume of earth to be moved will determine the most appropriate size and the attachments most likely to be of use. But the site - in terms of access, size, terrain and ground conditions - is also a major consideration when looking for the right excavator for the job.
Small machines are agile and have the upper hand when it comes to working in confined spaces. However, their size also needs to be matched to the site of the job. You would not use a teaspoon to dig a tree-planting pit. Likewise, you need to be sure the excavator reflects the amount of earth to be moved. Too small a machine will result in its capacity being over-reached and the operation will take longer, with the penalty of increased costs.
The machine chosen must also be capable of providing sufficient reach and digging depth. Dump height is important where soil has to be tipped into a lorry or skip. It is worth noting that the operating weight of any single model can vary depending on whether it is fitted with a cab or canopy and whether it has rubber or steel tracks.
Q: What are the advantages of micro and mini excavators?
A: Micro and mini machines have a lower pressure and less weight. That makes them particularly suited to landscape work where there are slopes or where the soil is liable to damage. They are also much easier to transport, requiring a smaller trailer and towing vehicle. But the biggest advantage is their cycle time. They are quick with the scoop-raise-swing-dump movement that is characteristic of digging equipment.
Q: Should I look at wheeled or tracked machines?
A: The type of sites and ground conditions need to be assessed when deciding on wheeled or tracked machines. Tracks have lower ground pressure and can give greater traction but the movement of such machines, although highly manoeuvrable and fast to reposition, can be slow in travelling across sites.
Wheels provide mobility and speed and are likely to do less damage to pavements and driveways. Remember that travel speed becomes important when lots of plots require working on the same site.
Q: Is it worth opting for an expandable undercarriage?
A: Machine width should reflect site access. Landscapers often need to move equipment through narrow areas to reach back gardens. I know of one occasion where the excavator had to be taken through a house. It is in these situations where the expandable undercarriage comes into its own. Many tracked micro and mini excavators have expandable undercarriages that "breathe in" to get through gateways
Q: What is the significance of zero tail-swing?
A: This feature is ideal where the smallest of space is available in which to work, such as when working close to barriers, existing landscape features, buildings or trees.
Q: Can I use the excavator to do jobs other than digging?
A: Most excavators come with a digging bucket or buckets but it is worth checking out other available attachments to see whether the machine can work in any other ways. Grabs, for instance, can be handy for loading the waste from tree-clearance jobs. You many also find uses for breakers and tampers. Some excavators even offer stump-grinder attachments.
When looking at the usefulness of different buckets and attachments, you should ensure that there is sufficient hydraulic capability and that the items can be quickly changed. A quick-change facility is essential if you are likely to use several different buckets - no operator wants to waste time trying to fit a new bucket.
Q: Are there any new attachments available?
A: Geko has introduced the Stump Beaver to bring stump-grinder capabilities to micro and mini excavators. Designed and built in the UK, it fills a gap in the small plant/tool hire market and is intended to be serious competition to walk-behind machines used by landscapers. Easy to adapt to various models, it is effective at low flow and pressure but also capable of handling higher outputs.
Q: How important is operator comfort?
A: Never underestimate its importance. A happy operator is a productive operator and, where long hours of work are anticipated, plant operators will expect a warm cab in winter but the ability to ventilate the workstation in summer. Seating should be fully adjustable and pedals, levers and joysticks within easy reach. Mounting and demounting the machine should be safe and struggle-free. Radio communication may be a consideration where the operator is likely to be working some distance from colleagues.
Q: What other factors should be considered?
A: The brand of machine you opt for may be influenced by the manufacturer's reputation, availability of equipment and spare parts, dealer back-up and service. Finance packages and the experience of your plant operator and mechanic should also be considered. It is always worth shopping around and enquiring about schemes such as lease hire.
Q: Should I buy new equipment or second-hand units?
A: You need to think about the likely frequency of use and the immediacy of jobs to be done. Remember that in the first year or two of operation, a new machine will generally be relatively free from costly repairs. Instead, inspections and regular servicing will be the prime consideration.
Although costing less to purchase, a used machine is more likely to need the expertise of a mechanic to diagnose problems and make repairs. Downtime and loss of income through breakdowns must be added into your calculations.
Q: How can I make our mini excavator secure?
A: There is a big demand for excavators of any size, with stolen plant often ending up abroad. Being easy to load onto a trailer, smaller excavators are relatively easy to steal. Most manufacturers offer enhanced security or "secure" keypad starting systems that make them less attractive to thieves. It is worth discussing additional security features with your dealer.
HEALTH AND SAFETY CONSIDERATIONS
Digging and earth moving are potentially dangerous operations. Work
should be properly planned, managed, supervised and carried out by
trained operators. The Health & Safety Executive recommends planning
against the following:
- Collapse of sides.
- Materials falling onto people working on the excavation site.
- People and vehicles falling into the excavated area.
- People being struck by kit - especially swinging arms and buckets.
- Undermining nearby structures.
- Contact with underground services.
- Access to the excavation site.
- Fumes.
- Accidents involving the general public.
