How to choose the right tracked mini dumper
Start from three things: how much weight it has to carry, where it has to get through and how it has to unload. Engine, tracks or wheels, transmission and tipping system follow from there.
1. Payload and skip volume. Payload is the maximum load in kilograms; volume is how much material the skip holds. With heavy materials you hit the weight limit first: a cubic metre of damp soil weighs 1,600 to 1,800 kg (3,500 to 4,000 lb), so a 0.26 m³ (9 cu ft) skip heaped with soil is already around 450 kg (990 lb).
2. Tracks or wheels. Tracks spread the weight over a wide area and are the right choice on mud, loose ground, lawns and sand, where a wheel would sink. The pneumatic tyres of the electric power barrows suit firm or paved surfaces such as yards, polytunnels, sheds and livestock buildings, and make the machine lighter and easier to handle.
3. Petrol, diesel or electric. A petrol or diesel engine has no range limit and is the choice for site work and heavy jobs. Electric runs with no noise and no exhaust fumes, so it works indoors and in residential areas too, and costs little to maintain.
4. Hydrostatic or gearbox transmission. With hydrostatic drive you set the speed smoothly with one lever, no clutch and no gears, and the machine brakes itself downhill. It costs more than a mechanical gearbox, but it is the professional choice, above all on slopes and for anyone working all day.
5. Self-loading shovel. The front shovel scoops up soil, sand, gravel and rubble and tips it into the skip without getting off the machine and without a spade. On site it saves one worker.
6. Tipping system. Front tipping is the most common. High tip lifts the skip before tipping, so you can unload straight into a van or a lorry. Side or swivel tipping is for depositing material along the route.
7. Machine width. Measure the narrowest gap on site: pedestrian gates, doorways, side passages. The DELEKS® range goes from 70 cm (27 in) on the compact 300 kg model to 87 cm (34 in) on the 500 kg hydrostatic dumpers.
8. Safety on slopes. Stability drops as the load rises and on soft ground. Always keep within the gradient limits in the model's manual and drive straight up and down, never turning or stopping across the slope.
Mini dumper, tracked dumper or power barrow?
Three names for the same family of machines. In the UK and Ireland "mini dumper" and "tracked dumper" come from the building trade, while "power barrow" and "motorised wheelbarrow" are what gardeners and landscapers tend to say. On DELEKS® product pages you always find the figures that matter: payload, transmission, tipping system and width.
Frequently asked questions
How much does a tracked mini dumper cost?
It depends on payload, engine and transmission. Electric power barrows and tracked models with a mechanical gearbox are the cheapest; hydrostatic machines with a self-loading shovel and a diesel engine are the dearest, and also the most productive. Up-to-date prices, VAT included, are on every product page.
Can a tracked dumper be used on hills and slopes?
Yes, within clear limits. Tracks grip better than wheels and hydrostatic drive lets you control speed and brake downhill without effort. Stability, though, depends on load and ground: keep within the gradient limits in the manual, drive straight up and down and reduce the load on soft or wet ground.
What is the maximum gradient for an electric power barrow?
It depends on the model and above all on the load: the fuller the skip, the lower the limit, and on soft, wet or grassy ground the figures drop further. For DELEKS® electric power barrows the limits for each load band are in the "Gradient table by load" sheet, downloadable from the product page. With heavy loads, work on level ground only.
Can it carry mud, liquids or concrete?
Mud and damp materials, yes: the skip is steel and the tracks cope well with mud. Loose liquids are not recommended, because they slosh about on the move and shift the centre of gravity, with a risk of tipping over on bends and slopes: use closed, secured containers. Fresh concrete can be carried by part-filling the skip and driving slowly.
What is high tip and will it load a van?
On high-tip dumpers the skip rises vertically before tipping, so you unload straight into a van, a lorry or a skip container with no shovelling and no second handling. Before buying, compare the tipping height on the product page with the height of your vehicle's tailboard.
When is side or swivel tipping the better choice?
When material has to be deposited along the route, for example backfilling trenches and excavations or unloading beside a narrow path without manoeuvring. With a swivel skip you can tip in several directions, up to 180°, without moving the machine.
How much does a mini dumper weigh and how do you transport it?
Wheeled electric models weigh around 100 kg (220 lb); tracked dumpers with a 300 to 500 kg payload weigh between 200 and 400 kg (440 to 880 lb), the larger ones more. They are loaded onto a van or trailer with two ramps, driving the machine up in reverse or at walking pace; the exact weight is on each product page.
How much maintenance does it need?
Not much: check the engine oil and, on hydrostatic models, the hydraulic oil, check track tension and clean the machine after working with mud or concrete. Service intervals are in the manual, and genuine spare parts are available on the website.
How long does the battery of an electric power barrow last?
A full charge usually covers a standard working day. Real range drops with heavy loads, frequent climbs and soft ground. On models with a removable battery, keep a second charged battery for long shifts.
How long does the battery take to charge?
From an ordinary 230 V mains socket, charging usually takes 6 to 8 hours, depending on the battery type and the remaining charge. The practical way is to charge overnight.
Lead-acid or lithium battery: which to choose?
A lead-acid battery costs less and suits regular use with full charges; keep it charged at all times. Lithium gives more range, faster charging, less weight and more charge cycles, and copes better with partial charges.
