The most perfect lift devices 2.000-12.500 kg
that have ever been invented *⁾

GPL^® Goods-Passenger Lifts

of loads from 900 to 12.500 kg and higher provide transportation of goods and accompanying persons. As a rule, the GPL-lifts of higher loads are adapted for loading / unloading by means of forklifts. The lifts are equipped with direct drives with two or four EC type pistons (telescopic with mechanical synchronization) or TCS (for narrow shafts) pistons. If it is necessary, the pawl devices are used additionally to stabilize the lift cabin’s floor during loading with forklifts.

GPL^® Goods-Passenger Lifts take advantage of the unique worldwide direct drive technique GMV 1:1 Technology, which keeps the cabin’s floor stable while loaded with few-ton forklifts. Moreover, the lift shafts are characterized by extremely small dimensions relative to the cabin size.

It is best described by the shaft utilization coefficient:

that has the biggest value out of all standard goods-passenger lifts. The shaft walls are characterized by light construction because forces are concentrated mainly on the shaft bottom and do not require dilatation.

These unique solutions in the world are valued for simple, easy in assembly construction and their longevity. The GPL-lifts can work at a very high frequency as a link in the production line. A perfect example is the two-level electronic plant in Kobierzyce near Wroclaw, where one of the GMV lifts is GPL^® 4.000 kg working in 3-shift cycle, 7 days a week. Number of cabin starts recorded by the registering device reached 1 million over the last three years. That means that the cabin passing the distance of 6 m up / down, covered at that time more than 6,000 km. Maintenance, apart from regular inspections, has been limited to a single cylinder seals replacement.

The biggest of the standard lifts is SUPER – GPL^® (S-VL^®) of loads from 6.000 to 12.500 kg. The cabin dimensions WxD 3,4 x 6,0 m and with door WxH 3,0 x 2,6 m enable the lift free loading/unloading by means of forklifts. In case of special orders, GMV works out also a non-stardard lifting devices and special lifts of very big loads (more than 10 tons). The lift engine room can be located in any place, ever far away from the shaft.

Important parameter - force on the cabin’s sill F_s

Goods-passenger lifts must meet strict requirements because they work in severe conditions. They not only transport weighs of several tons, but the loading is carried out by means of such devices as pallet trucks or massive fork-lifts. The design of key structure elements should be strong enough to withstand forces and torques (T_s). Normally, the characteristics include such parameters as load capacity and dimensions of the cabin and doors. However, the usefulness of a lift to work hard determines the force on the cabin’s sill. In the case of load capacity equal or higher than 2500 kg, the lift standard recommends to take into the consideration the F_s force equal to:

• 60% of the rated load Q (e.g. loaded by pallet trucks), in KG


F_s = 0,6 • Q


Example: Q=3000 kg, minimum force on the sill F_s = 1800 kG.



• 85% of the rated load Q (loaded by fork-lifts)


F_s = 0,85 • Q


Example: Q=4000 kg, minimum force on the sill F_s = 3400 kG.

In many factories in the world, there are operating inappropriate goods-passenger lifts. Once they run for the first time, it turns out that they can be loaded only with small devices and despite the large cabins, they are often overloaded. Incorrect selection of right lifts in a factory usually reflects its lower efficiency.
The range of GMV goods-passenger lifts parameters is huge, so you should take advantage of our experience.

*⁾A great advantage over other technical solutions – in particular over traction goods lifts:

Technology and functionality

• The direct drive using a unique in the world technique GMV 1:1 Technology.
• Telescopic pistons type EC/TCS of GMV Sweden AB production with 100 percent synchronization impacting the lift operation and longevity (impossible to be reached by other solutions).
• Very high value of the maximum force on the cabin’s door sill allowing the forklifts loading the lifts from 2 tons on.
• High durability and reliability due to the small number of parts (including rotating ones).
• Low operating and maintenance cost.
• Simple and ultra light construction in comparison with other electric and hydraulic vehicle lifts.
• Exceptionally small size of the lift shaft with respect to the cabin’s dimensions.
• Minimum pit of 1,0 m.
• Exceptionally stable cabin’s floor position during vehicles entering – it is not possible to be achieved in case the lift car is mounted on ropes (hydraulic 1:2 and traction 4:1 goods lifts ).
• Standard load range from 2,0 up to 12,5 t and optional over 12,5 t.
• High resistance to asymmetrical loading of the cabin.
• Possibility of increasing load capacity at constant cabin size.
• Central door enabling quick and safe loading.

• Material-saving construction of the GPL-lift, low total weight (even by 40-60% lower in comparison with other electric and hydraulic goods lifts), what means also lower energy consumption needed to manufacture and transport the lift.

• A small number of parts of which the lift is built.
• Low demand for spare parts due to high durability and reliability.
• Light and material-saving shaft construction thanks to forces concentration on the shaft bottom.
• No drive with permanent magnets, the production of which is exceptionally energy-consuming and their utilization is difficult and expensive.
• Low energy consumption.

• More than 60 years of experience in hydraulic lifts construction.
• No massive units (a drive and a counterweight) over the lift cabin.
• No ropes on which the lift cabin is mounted.
• Machinery room is located in a separate place what secures safe assembly and maintenance.

GOODS-PASSENGER LIFTS LOADING/UNLOADING

The GPL^® Goods-Passenger Lifts with the GMV 1:1 Technology are used in the buildings in which there is a need to transport heavy large-size goods and/or persons. The GMV lifts are the perfect solutions in multilevel store buildings and production plants. The GMV solutions integrate horizontal and vertical migrations of goods into one effective and very efficient internal logistic system.

The selection of a proper goods-passenger lift must be always preceded by a deep analysis of possibilities and needs of a future user. Store buildings and production plants do not function without forklifts and that is why the goods-passenger lifts of large-size cabins and high loads should be adapted for entering of such type loading equipment fully loaded.

I.  Direct mode

The lift is adapted to transport forklifts together with loaded goods. The lift operation frequency can be high: on average 10-20 travels/hour.

The minimum force on the cabin’s sill, by lift standard EN 81-2, equals F_s = 0,85·Q (for load Q ≥ 2500 kg).

II.  Sequential mode

The lift is loaded with one forklift truck and unloaded with a second one on another level. The lift operation frequency: moderate, on average 5-8 travels/hour.

The minimum force on the cabin’s sill F_s = 0,85·Q (for Q ≥ 2500 kg).

III.  Alternating mode

The alternating operation mode exists if the lift is not adapted to loading with forklifts (low maximum force on the cabin’s sill), but only with small palette trucks. Goods are delivered to the so called reloading zone from where they are next taken by workers who serve palette trucks to fill the floor in the lift cabin. It is not possible to place goods one on another and the real load equals to the sum of palette weights placed on the lift cabin floor. The lift operation frequency: low, on average 3-5 travels/hour.

In case of loading the cabin by means of palette trucks, the minimum force on the cabin’s sill equals F_s = 0,6·Q (for Q ≥ 2500 kg).

The alternating mode is of low effectiveness because almost always the real load is much lower than nominal one. This difference can reach even up to several tones. Note: there exists a high risk of attempts to load with forklifts the lifts which are not adapted to such loading. That is why GMV recommends for operation in the alternating mode the lifts with small-size cabin which cannot be entered by the forklifts.

IV.  Simple mode

The lift simple operation mode is applied in small production plants, workshops, warehouses or shops. Lack of forklift trucks causes that goods (as a rule of low weight) are manually reloaded into boxes and next transported with palette trucks. The goods-passenger lifts are of low loads (usually up to 1,6 t) and are not intensely used.

For loads less than 2500 kg the lift standard recommends force on the sill F_s = 0,4·Q.

GMV delivers the GPL^® lifts that operate in all 4 modes. The great majority of competitive companies offer goods-passenger lifts that operate only in the alternating and simple modes (hydraulic goods-passenger 1:1 and 1:2 lifts and traction goods-passenger lifts including traction MRL ones).

Thanks to unique GMV 1:1 Technology GMV has been a leader in the GPL - lift solutions for many years.
