New generation of drives for hydraulic and electric cranes (elevators)

25 of December '20

GMV electric and hydraulic cranes for any type of project


The GMV Polska Sp. z o.o. company was founded in 1958 and is now the largest global manufacturer of hydraulic drives for elevators (elevators). We can find more than 750,000 working cranes with GMV drives worldwide. Each year the company adds to this statistic, supplying tens of thousands of new ones to the global market. In recent years, GMV has launched new generations of drives for hydraulic and electric cranes.

GMV crane types

GMV offers crane components and complete hydraulic and electric cranes.

GMV hydraulic cranes

Principle of operation of a hydraulic-powered lift

The cabin of a hydraulic-powered elevator moves upward thanks to an actuator set in motion by working fluid pumped under pressure. The downward movement of the cabin is carried out by gravity, without the consumption of electricity by the motor, and the fluid is returned back to the tank. The precise movement of the cabin in both directions is supervised by an electronically controlled valve unit.

The shafts of hydraulic cranes are characterized by extremely small dimensions in relation to the cabin, lightweight wall construction, as the forces are mainly concentrated at the bottom of the shaft and do not require expansion joints. This allows optimum use of space and increases the usable / habitable area in the building. The placement of the drive unit outside the shaft contributes to extremely low noise levels, which is why hydraulic cranes are especially recommended for residential buildings. In addition, hydraulic cranes are famous for their long service life (20 or more years), as they have an uncomplicated design and a small number of moving parts. For this reason, operating costs are extremely low.

Drive of hydraulic cranes by design

  • direct (1:1) - the actuator directly drives the cabin frame
  • indirect (2:1) - the actuator acts on the cabin frame, via the pulley and cables.

Direct drive is used for cranes with lower lift heights and higher lifting capacities. The drive unit contains a working fluid unit in which the motor and a coupled pump are immersed.

GREEN LIFT hydraulic cranes - FLUITRONIC

GREEN LIFT are standard type-tested hydraulic cranes. The name FLUITRONIC emphasizes the use of the latest generation drive with microprocessor control. They are equipped with a state-of-the-art NGV proportional valve block unit, which provides a very high level of cabin ride comfort. The accuracy of stopping at the threshold at the stop is 3 mm. GREEN LIFT crane cabs, are modular structures with one or two entrances. The interior can be freely arranged using a wide range of flooring and cabin wall panels: laminated or steel.

GREEN LIFT GLT electric cranes

For higher lifting heights (from 17 to 35 m), GMV recommends European type-tested electric cranes with lifting capacities from 320 to 1,000 kg with a gearless drive unit with VVVF frequency control. Driving speeds of up to 1 m/s, very high driving comfort, low noise emissions and precise stopping of the cabin at the stop are assured. In the event of a power failure, the UPS-assisted control (230 V - battery group) will enable the crane to reach the nearest stop and open the door, and passengers will be able to freely exit the cabin. The drive unit is attached to the top of the guides that transfer the load to the bottom of the shaft. This makes the shaft a lighter and less expensive design.

HOME LIFT® hydraulic elevators - 2006/42/EC

Elevators named Home Lift meet the requirements of the 2006/42/EC Machinery Directive. Unlike other equipment available on the market, they retain the features of passenger lifts: automatic arrival at the assigned stop and automatic cabin and shaft doors. Speed, as required by the directive, does not exceed 0.15 m/s. Lifting capacity from 250 to 400 kg (3-5 persons). They are designed for low-traffic buildings and private homes.

GPL freight and passenger cranes and VL truck cranes

A separate group is made up of goods and passenger cranes with lifting capacities in the range of 1,500 to 9,000 kg by GMV Sweden AB. We use direct drives (Technology GMVTM 1:1) with two or four EC-type actuators (telescopic with mechanical synchronization). These world-unique solutions are valued for their simple, easy-to-install design and durability. We also develop non-standard systems and special cranes on request. We especially recommend our solutions when applied to cranes with very high lifting capacities (over 10 tons). The crane engine room can be located anywhere, even away from the shaft. VL car cranes are gaining popularity among architects. They serve multi-level surface and underground parking lots. It turns out that this is often the only solution for providing garage spaces under buildings in city centers.

Stairs and escalators

GMV is a supplier not only of lifting equipment (elevators), but also of stairs and escalators. This is a nod to investors and architects who expect comprehensive solutions from a reputable lift manufacturer. Our equipment is used in commercial buildings: shopping malls, exhibition centers or office buildings, as well as in public transport facilities such as subways, railroad stations and airports.

***

GMV has been in existence for 60 years. It is one of the few companies in the world that manufactures both hydraulic and electric cranes. Its wide range of products provides freedom in choosing the right solution for the building being designed, which is why more and more buildings in Poland are equipped with modern and safe GMV cranes. Architects, designers, crane companies and users have appreciated their advantages for many years.
