A freight lift is sized from the load: how much it weighs, what its dimensions are and how it is brought into the car, on a trolley or by hand. The next question is whether a person travels with the load. The drive, the doors and the control stations depend on these answers.
Certificate limits
For electric lifts of type IRL, that is, the German and IZA models, the current design examination certificate sets a limit of 3500 kg at a speed of 1.0 m/s. The Genesis series ends at 2000 kg. The hydraulic type IH lifts up to 6000 kg, but to a height of up to 22 m and to no more than eight stops. If a heavier load or greater travel is needed, we establish which document covers such a lift before the contract.
| Rated load, kg | Shaft, mm | Car, mm | Doors, mm | Power at 1.0 m/s, kW |
|---|---|---|---|---|
| 1000 | 1850×2500 | 1100×2100 | 1000 | 8,4 |
| 1275 | 1950×2700 | 1200×2300 | 1100 | 8,4 |
| 1600 | 2150×2900 | 1400×2400 | 1300 | 10,7 |
| 2000 | 2250×3200 | 1500×2700 | 1400 | 13,4 |
The table shows the machine-room-less Genesis 22, with data from the technical catalogue. The pit for this model is 1200 mm and the headroom 3300 mm; with the additional safety system the pit is reduced to 1000 mm.
Where there is already a machine room above the shaft, the version with an overhead traction machine is installed. For 1000 kg the catalogue gives a shaft of 1800×2500 mm, for 2000 kg 2200×3200 mm, with a pit of 1200 mm and headroom of 3400 mm at a speed of 1.0 m/s.
Electric or hydraulic
According to the manufacturer's description, a hydraulic drive is chosen for loads from 1500-2000 kg. The hydraulic power unit stands in a separate room next to the shaft, on any floor; on our Kyiv project it is on the ground floor. An electric lift is needed where there are more than eight stops or the travel exceeds 22 m.
Car and doors
The Standart car has walls of plastic-coated metal in RAL 9007 and a matching flat ceiling. The floor is covered with wear-resistant rubber, and the corners, handrail and car operating panel are Inox Satine stainless steel. The indicators are segment type and the buttons are square. The car and door heights are ordered to suit the size of the load.
There are three kinds of landing doors. Manual double-leaf swing doors with a primer coat are the simplest. Automatic sliding doors are made of plastic-coated metal or of stainless steel.
With or without an attendant
An attended lift has a car operating panel: a person enters together with the load and selects the floor. An unattended lift is controlled only from the landings: it is loaded, the doors are closed and it is sent off with a button. We have installed both variants.
- Kyiv, attended freight lift: 2000 kg, overhead machine room, 2014. The photos at the bottom of the page are from there.
- Dolyna: unattended, electric, machine-room-less, 2013.
- Kyiv: hydraulic, unattended, 2014.
- Ivano-Frankivsk, Mens shopping centre: 1000 kg passenger and freight lift in the Classic version, 2021. While the centre was being renovated, the car was lined with OSB board.
Dumbwaiters
A kitchen dumbwaiter carries dishes and tableware between the kitchen and the dining room; it does not carry people. According to the manufacturer's description, the car and its door are made of Inox Satine stainless steel. The door opens vertically, and there is a removable shelf inside. The drive is three-phase and geared, and the machine sits in the upper part of the shaft, so no separate machine room is needed. The rated load is 100 or 150 kg.
The lift certificates do not name dumbwaiters. We show which document comes with a specific product before the contract is signed.
For a calculation, describe the load, its weight and dimensions, the number of stops and the loading method. Freight lift request.
