Model 5 Shredder vs UMS250: Parameter Comparison

Two twin-shaft primary shredders in the same size class, both tracked, both built to reduce bulky material before a second process: the Model 5 and the UPSEN UMS250. Buyers comparing them usually have two specification sheets in front of them and no way to tell whether the numbers are measured the same way. This page puts the two side by side and marks exactly where the figures are comparable and where they are not.

One point of method before the table: the Model 5 column is taken from the manufacturer's brochure, and that brochure states its performance data are approximate and not guaranteed. The UMS250 column is our own published specification. Where a sheet does not state a value, the cell below is left empty rather than filled with an assumption.

The two machines side by side

1. Engine: same class, 14 kW apart

The Model 5 brochure specifies a CAT C4.4 rated 140 kW / 188 hp at Stage V. Our UMS250 sheet specifies a Cummins QSB5.9 rated 154 kW / 210 hp. That is 14 kW more on paper, about ten per cent, and it is the kind of gap that shows up when the rotor is loaded with dense material rather than timber: a shredder's real limit is usually torque at the shaft, not flywheel horsepower.

Do not read the two figures as a verdict on either engine. A C4.4 and a QSB5.9 are different displacements and different emission strategies, and the rated number is taken at a different point on each curve. What matters to a buyer is simpler: which engine your local dealer can service, which one your mechanics already know, and whether the emission tier matches the country the machine will work in. Our sheet does not quote an emission tier for the UMS250 engine, so ask us to confirm it against your market before you order.

2. Rotor: 680 mm both, 50 mm of working width between them

Both machines turn a 680 mm diameter shaft. The Model 5 shaft is 1,500 mm long; the UMS250 shaft is 1,550 mm. Fifty millimetres is under four per cent, but on a twin-shaft machine the shaft length is the working width of the chamber, so it sets how much material is in the cut at any moment and therefore how the load is spread across the cutters.

Speed differs more: the Model 5 tops out at 35 rpm, the UMS250 runs 0–40 rpm. Higher shaft speed gives a faster reduction cycle and a finer average product; lower speed gives more torque per revolution and less wear per tonne. That is a tuning question rather than a quality question, and both machines are judged by what comes out of the discharge, not by the tachometer.

The materials differ too. The Model 5 brochure offers two shaft builds — one for concrete, asphalt and C&D, one for wood, scrap metal, biomass and plastics — and ships with one of them fitted. Our UMS250 sheet specifies HARDOX 500 / NM500 cutters and a 160,000 N·m reducer. Neither sheet tells you which shaft is right for your feed; that is a conversation, not a table row.

3. Capacity: why the tonnages do not line up

On paper the two machines are close on construction and demolition waste — 80–100 t/h for the Model 5, 80–130 t/h for the UMS250 — and far apart on wood, at 10 t/h against 15–20 t/h. Before either number is used to size a plant, three things need to be separated.

First, the brochure itself says its performance data are approximate and not guaranteed, depending on configuration, shaft choice and whether the feed is optimal. A range quoted that way is an indication, not a contract. Second, wood tonnage is dominated by bulk density and by whether the machine is fed continuously: a light, fibrous material can fill a chamber by volume long before it loads the rotor by mass, so two machines with similar chambers can post very different wood figures purely because of how they were tested. Third, a machine quoted on C&D at 80–100 t/h and one quoted at 80–130 t/h may have been run on different rubble, at different moisture, with different support equipment.

The practical reading: treat both capacity columns as the shape of the machine's appetite, not as a guaranteed output. If your business case depends on a specific tonnage, ask for the conditions behind the number — material, bulk density, discharge setting, and whether the figure was measured over a shift or extrapolated from a short run.

4. Weight and transport envelope

The Model 5 is quoted at 15.1 t including the magnet. The UMS250 is 18,000 kg. That is 2,900 kg more, about nineteen per cent, and it shows up in the transport envelope: 6,939 mm transport length against 7,860 mm, and a working length of 7,797 mm against 8,670 mm.

Width is identical at 2,200 mm, which matters more than length for most European road moves, and transport height is within 31 mm (2,619 mm against 2,650 mm). If your moves are short and infrequent, the extra 900 mm of length costs little. If you relocate every few weeks and your haulier prices by trailer class, the lighter, shorter machine is easier to schedule.

One structural difference belongs here rather than in the options list: the Model 5 brochure lists a hook-lift body as standard, so the machine can be loaded and unloaded by a hook-lift truck without a low-loader. Our UMS250 sheet describes a tracked chassis and does not state a hook-lift body. If hook-lift transport is a requirement in your fleet, raise it explicitly and we will confirm what can be supplied.

5. Discharge height and the machine downstream

The Model 5 discharges at 3,100 mm; the UMS250 stacks at 2,800 mm. Those 300 mm decide what the conveyor can do next. A 3,100 mm discharge clears a standard haulage container and builds a taller windrow, which reduces how often a wheel loader has to push up. A 2,800 mm discharge is the more convenient height for feeding a secondary screen or a stacker conveyor directly, because you are not lifting material higher than the next process needs.

Neither figure is better in the abstract. If the shredded product leaves site in containers, take the higher discharge. If it goes straight into a screening line, the lower one saves conveyor length and a transfer point.

6. Configuration and options

The Model 5 brochure is unusually explicit about its build, and that detail is worth listing because it is what a buyer compares in a tender:

• Folding magnetic separator, hydraulic side comb adjustment as an option, and a dust suppression system quoted at up to about 85 per cent reduction, which needs an external water supply.
• A cassette shaft design, with shaft changes quoted at under two hours.
• Three operating modes — wood, universal, asynchronous — selected to suit the material.
• Remote control plus a wired controller as a backup, telematics for remote diagnosis, and a modular control box said to be replaceable in minutes.
• Options including a reversible engine fan, custom paint, tilting hopper, fire suppression, custom screens and shafts, and a custom impact and side plate set that pushes product below 60 mm at the cost of capacity.
• Add-ons including a spare shaft set, a conveyor screener and an extended warranty of 18 months or 1,500 hours, whichever comes first.

Our UMS250 sheet lists what we publish: HARDOX 500 / NM500 cutters, closed-circuit Linde hydraulics, a 160,000 N·m reducer, a B650×2,000 iron separator and a B800×9,000 main conveyor. It does not itemise every option, and an absent line on our sheet is not evidence that a feature is unavailable — it means we have not published it. Send the tender list and we will answer line by line.

7. How to read a comparison like this

• Ask what was measured. A tonnage without material, bulk density and discharge setting is a marketing figure.
• Check the weight basis. With or without magnet, with or without hopper extension, fuel and operator excluded — three sheets can quote the same machine three ways.
• Separate structure from options. Hook lift, tilting hopper and hydraulic side combs change the transport and operating envelope; they belong in the comparison, not in a footnote.
• Compare like emission tiers. A Stage V engine and an unregulated one are different products for most Western tenders.
• Price the whole line. Shredder, magnet, conveyor and screen, plus the transport class each one forces you into.

8. Data basis for this comparison

The Model 5 column comes from the manufacturer's brochure as supplied to us in translation. That brochure states that technical data are subject to continuous change and that dimensions may vary, and it marks its performance figures as approximate and not guaranteed. Its reduction-ratio chart is a reading from a bar chart with a stated tolerance of about ±0.5, so we have not reproduced those ratios here.

The UMS250 column is our own published specification for the machine we build. Where the two sheets use different units or different definitions — hopper volume against hopper opening, for example — we have left them as stated rather than converting one into the other, because a converted figure invites a comparison that was never measured.

Frequently asked questions

Are the Model 5 and the UMS250 the same machine?

No. They are both twin-shaft tracked primary shredders with a 680 mm shaft, but they differ in engine, shaft length, weight, transport length, discharge height and published capacity. Only the shaft diameter matches exactly.

Which one is heavier, and does it matter?

The UMS250, at 18,000 kg against 15.1 t. It matters mainly for transport class and ground bearing pressure: a heavier machine needs a suitable haulier and a firmer pad, but it also carries more mass into the cut.

Why is the wood figure so different from the C&D figure on both machines?

Because wood is light and compressible. It fills the chamber by volume long before it loads the rotor by mass, so a chamber that runs 80–130 t/h on rubble may only pass 15–20 t/h of timber. The two figures describe different materials, not different quality.

Can the UMS250 be supplied with a hook-lift body?

Our published specification describes a tracked chassis and does not state a hook-lift body. Tell us the truck type in your fleet and we will confirm what can be built.
