SECTION 01 - PRESENTATION

GMV was founded in 1958 and is today the major manufacturer of components for hydraulic elevators.
GMV headquarters are located in Pero, near Milan,
and the company can rely on a broad network of partners and distributors all over the world.
GMV manufactures a wide range of single stage jacks, telescopic jacks, power units
and the corresponding accessories to be able to meet the most different requirements of their customers.

SINGLE STAGE JACKS :
Two main models are available: type for a direct acting arrangement (1:1) and type for indirect acting arrangement (2:1).
The maximum static pressure for these jacks is 45 bar.
They can also be supplied in 2 or 3 pieces (to facilitate transportation).
* type 1000 direct acting below jack (rams from ° 60 up to ° 238mm)
* type 1001 direct acting at side jack (rams from °60 up to °150mm)
* type 1008 indirect acting at side jack 2:1 (rams from °60 up to 238mm)
* type 1008bis indirect acting at side jack 2:1 with threaded head (rams from °50 up to °80mm)

TELESCOPIC JACKS WITH HYDRAULIC SYNCHRONIZATION :
The hydraulically synchronized system brings about the simultaneous extension of the stages
and guarantees a constant car speed.
The maximum static pressures are 45 bar for two stages jacks and 40 bar for three stages jacks.
The following dimensions can be supplied:
* type 9100 two stages direct acting at side (from ° 42 up to °100 mm)
* type 9101 three stages direct acting at side (from ° 42 up to °100 mm)
* type 9110 two stages  direct acting below  (from ° 50up to ° 100 mm)
* type 9111 three stages  direct acting below (from ° 50up to ° 100 mm)

TELESCOPIC JACKS WITH MECHANICALSYNCHRONIZATION :
Mechanical synchronization is achieved by means of a chain system
which links the different moving elements of the jack.
This system is most suitable for big installations requiring also 4 or 8 jacks.
Maximum static pressure is 40 bar.
They can be supplied as EC version (external guide yokes ISO T40 T50 )
or TCS version (external guide yokes ISO T50/A):
* TCS, EC - 2N two stages without external guide yokes (TCS, EC 60-2N ¸TCS, EC 120-2N)
* TCS, EC - 2Y two stages with external guide yokes (TCS, EC 60-2Y¸TCS, EC 120-2Y)
* TCS, EC - 3Y three stages with external guide yokes (TCS, EC 60-3Y¸TCS, EC 105-3Y)
* TCS, EC - 4Y four stages with external guide yokes (TCS, EC 60-4Y¸TCS, EC 90-4Y)

POWER UNITS:
The power unit production includes a wide range of three phase
and monophase motor-pump groups with frequency 50 and 60 Hz.
* single phase power units 50Hz - power: 1,5 ¸2,2 kW, pump flow: 13 ¸37 l/min
* single phase power units 60Hz - power: 1,8 ¸2,6 kW, pump flow: 16 ¸45 l/min
* three phase power units 50Hz - power: 2,2 ¸58,8 kW, pump flow: 25 ¸600 l/min
* three phase power units 60Hz - power: 2,2 ¸58,8 kW, pump flow: 30 ¸600 l/min
