An Izamet lift series is chosen from three inputs: how many kilograms to carry, to what height, and what shaft exists or can be built. This page has two layers of figures. The type limits are taken from the annex to design examination certificate No. UA.TR.006.DEC.109502-25, and the shaft and car dimensions from the manufacturer's technical catalogue.
Certificate limits
| Type and models | Speed, m/s | Rated load, kg | Travel up to, m | Max. stops |
|---|---|---|---|---|
| IBL: Genesis 12, 21, 22, EnEf | 1,0 | 320-2000 | 60 | 25 |
| IBL: the same models | 1,6; 2,0 | 600-2000 | 60 | 25 |
| IRL: German R, German S, IZA | 1,0 | 320-3500 | 50 | 16 |

| IH, hydraulic | 0,16-0,63 | 320-6000 | 22 | 8 |
For each type the certificate allows versions with and without a machine room. The landing and car doors are sliding, centre-opening or side-opening. TEMAZI Ltd is recorded as the manufacturer of the models in the table, with production in Dupnitsa, Bulgaria.
Genesis and EnEf: gearless belt drive
Type IBL means gearless lifts. A synchronous motor turns a small-diameter sheave, 86-114 mm according to the catalogue, and the car is carried by traction belts with a polyurethane coating. They need no lubrication. The certificate requires something else: periodic inspection of the condition of the belts in line with the manufacturer's instructions, so this inspection is part of the maintenance plan.
Lifts up to 1000 kg have a cantilever suspension, also called a rucksack suspension: all the equipment is fixed to a single load-bearing wall. The other shaft walls can be lightweight or glass, so this layout is chosen for panoramic lifts and for cars with entrances at a 90° angle. The EnEf traction machine is placed beside or behind the car, and this determines the shape of the shaft.

For a single rated load the catalogue gives several shafts; one or two per model are shown here. The 1000 kg Genesis 21 has a wide, shallow car of 2100×1100 mm with a 1200 mm door, while the Genesis 22 has a deep one, 1100×2100 mm.
Pit and headroom

| German S | 1,6 | 1300 | 900 | 3600 | 3150 |
A shallower pit is possible with an additional safety system. In the certificate this is recorded as a deviation from clause 5.2.5.8.1 of DSTU EN 81-20:2022 with compensating measures under DSTU EN 81-21: a pre-triggered stopping system, a monitoring contact on the lowest landing door, and a telescopic or folding apron under the car sill. The certificate provides for reduced headroom for types IRL and IH, where a folding balustrade on the car roof is added.

The power supply is three-phase, 380 V. In machine-room-less lifts the controller cabinet stands next to the top landing door; according to the catalogue it measures 185×2000×110 mm.
German R and German S
In the certificate this is type IRL. The technical catalogue gives German R for 320-600 kg at a speed of 1.0 m/s and German S for 400-750 kg at a speed of 1.6 m/s. Both are machine-room-less, with the traction machine beside or behind the car. We installed a German R in the Classic version, with a geared rope drive, in Yaremche.
| Model | Rated load, kg | Shaft A×B, mm | Car C×D, mm | Door E, mm |
|---|---|---|---|---|
| German R | 320 | 1400×1350 | 800×980 | 750 |
| German R | 400 | 1500×1500 | 900×1130 | 850 |
| German R | 450 | 1550×1700 | 950×1330 | 900 |
| German R | 600 | 1700×1770 | 1100×1400 | 900 |
| German S | 400 | 1500×1630 | 900×1260 | 850 |
| German S | 450 | 1600×1630 | 1000×1260 | 900 |

| German S | 750 | 1700×2000 | 1100×1630 | 1000 |
Hydraulic IH
A hydraulic drive is chosen for low travel. The certificate limits type IH to 22 metres of travel and eight stops, a speed of 0.16-0.63 m/s and a rated load of 320-6000 kg. The hydraulic power unit stands in a separate room next to the shaft and can be located on any floor. For this type the annex to the certificate records the R10 rupture valve and the L10 safety valve made by Blain Hydraulics (Germany).
Designations that are not in the certificate
The technical catalogue contains other names as well: Genesis RS, RS 2, CP and 41, the LP14 lift, and the IWG version with the machine room above the shaft. They are not in the list of models of the current certificate, so we give no tables for them here. If a project needs exactly such a version, before the contract we show the document that applies to the specific lift.
For a selection, send us the shaft plan dimensions, the pit depth, the headroom height and the number of stops. The on-site survey is free, and you can leave a request here.
