The choice between the M300 and the M670 is usually made by the building itself: either there is a machine room above the shaft or there is not. The rest, namely rated load, speed and car size, is then selected within the platform. Below are the limits from the annexes to the EU certificates and the dimensions from the factory specifications.
| Parameter | M300 | M670 |
|---|---|---|
| Machine room | none, traction machine at the top of the shaft | above the shaft |
| Rated load | 450-2000 kg | 320-2500 kg |
| Rated speed | 1.0-2.5 m/s; up to 600 kg, no more than 1.75 m/s | 0.63-2.5 m/s |
| Maximum travel (rise) | 100 m up to 600 kg, 130 m above that | 150 m, up to 63 stops |
| Roping | 2:1 | 1:1 or 2:1 |
| Drive | gearless synchronous traction machine, VVVF | gearless synchronous traction machine, VVVF |
| Controller | SJEC i-hold or e-hold | SJEC i-hold |
M300: without a machine room
This is the platform for buildings where nothing is built above the shaft. For each rated load, the annex to the certificate gives the smallest car and its largest floor area.
| Rated load | Persons | Smallest car, mm | Maximum car area, m² |
|---|---|---|---|
| 630 kg | 8 | 1100×1400 | 1,66 |
| 800 kg | 10 | 1100×1400 | 2,0 |
| 1000 kg | 13 | 1100×2100, 1600×1400 or 1400×1600 | 2,4 |
| 1250 kg | 16 | the same three options | 2,9 |
| 1600 kg | 21 | 2000×1400 or 1400×2000 | 3,56 |
| 2000 kg | 26 | 2000×1400 or 1400×2000 | 4,2 |
Two restrictions from the certificate: lifts for 450-600 kg may be installed only in existing buildings, and for an 1100×1400 mm car in a new building the doors must be at least 900 mm wide.
M670: with a machine room
Here the certificate sets a range of car widths and depths, so the car is easier to fit to an existing shaft.
| Rated load | Persons | Car width, mm | Car depth, mm |
|---|---|---|---|
| 630 kg | 8 | 1000-1650 | 1000-1650 |
| 800 kg | 10 | 1000-2000 | 1000-2000 |
| 1000 kg | 13 | 1100-2150 | 1100-2300 |
| 1600 kg | 21 | 1350-2500 | 1350-2500 |
| 2000 kg | 26 | 1400-2500 | 1700-3000 |
| 2500 kg | 33 | 1500-3000 | 1700-3400 |
The car height is 2000-3200 mm, and the doors are from 600 mm wide. According to the annex to the certificate, the pit starts at 1100 mm and the headroom at the car height plus 1200 mm; both figures increase with speed. The catalogue has no separate hospital range; a 1400×2400 mm bed car falls, by its dimensions, within the M670 range for 1600 kg.
Drive and controls
The traction machine is a gearless permanent-magnet synchronous type. According to the factory catalogue, it uses 30-60% less energy than a geared machine and runs with less vibration and noise. The variable frequency drive is closed-loop, that is, it uses feedback from the motor encoder.
The controller combines the drive and the logic in a single unit. According to the catalogue, it saves up to 90% of energy in standby mode; regeneration to the mains is fitted as an option. The basic specification includes unintended car movement protection (UCMP), automatic re-levelling, a door light curtain, a five-way intercom and fire recall mode.
In the basic specification, rescue on power failure is gravity-based: the brake is released and the car moves to the nearest floor. We agree a configuration with battery-powered rescue when the order is placed.
Shaft examples from the factory specifications
| Lift, 1.0 m/s | Car, mm | Doors, mm | Shaft, clear dimensions, mm | Pit and headroom, mm |
|---|---|---|---|---|
| M300, 630 kg | 1100×1400×2150 | side-opening, 900×2000 | 1700×1800 | 1250 and 3550 |
| M300, 1000 kg | 1300×1700×2100 | side-opening, 1000×2000 | 1900×2300 | 1200 (to EN 81-21) and 3500 |
| M670, 1000 kg, existing shaft | 1600×1400×2200 | centre-opening, 1000×2000 | 2218×2135 | 1400 and 4043 |
The factory builds the panoramic lift on the M300 platform. In the 630 kg specification the walls, car doors and landing doors are glass in a stainless steel frame, and the standard pit and headroom are 1250 and 3600 mm. The smallest pit the factory agrees to is 900 mm, to EN 81-21. Only clear glass is available.
If your shaft is not in the table, send us its width, depth, pit and headroom. We will check against the annex to the certificate which car fits it.
