Are electric chain hoists from GIS suitable for outdoors use?
The GP / GPM series feature as standard protection class IP 65 (dust-tight and protected against water jets), which allows outdoor use without any problems. The GCH series can optionally be upgraded to IP 65.

 

Why does GIS use contactor controls for electric chain hoists?
Electric chain hoists and motorised trolleys from GIS are equipped with a 42 V contactor control as standard. With the control voltage of 42 V, the limit switch for the upper and lower hook position of the chain hoist is driven. Due to safety reasons low voltage with 42 V is used as a control voltage instead of using the operating voltage (110V-600V).

Can you recommend an electric chain hoist that is very quiet?
The GIS electric chain GPM 250 from the new series GP is with 65 db. (measuring distance 1 m), thanks to its 3-stage gearbox with helical gearing very quiet compared to commercially available chain hoists.

What are the advantages of profile-steel chains?
In comparison with traditional round-steel chains, profile-steel chains as used with the electric chain hoist GPM have a significantly higher safety factor which reduces the wear out and extends the service life.

What capacities are single-phase electric chain hoists suitable for?
GIS 1 phases - electric chain hoists can be used for a lifting capacity of 2000 kg. For maximum capacities the hoisting speed is reduced to 2 m/min. Power driven trolleys in 1 phase design are available for the electric chain hoists.

What is the temperature range for the use of electric chain hoists?
GIS electric chain hoists in the standard version are suitable for the temperature range - 15° to + 50°. For ambient temperatures below the minimum and above the maximum special versions are used.

Are trolleys equipped with a fall protection?
All GIS manual and electric trolleys are equipped with a safety rail.

Can GIS trolleys manoeuvre around curve radii?
Depending on the chassis type curve radii can be driven. Detailed information can be found on our technical sketch.
EHF/EMFE  50   =   minimum curve radius 1'200 mm
EHF/EMFE 150   =   minimum curve radius 1'500 mm
EHF/EMFE 300   =   minimum curve radius 1'800 mm
EHF/EMFE 500   =   minimum curve radius 1'800 mm
