What does IP protection class mean?
The degree of protection designation is always shown by the letter pair IP appended by two digits. These indicate the degree of protection of a casing with regard to contact and foreign bodies (first digit) and moisture or water (second digit).

Electric chain hoists
Are electric chain hoists from GIS suitable for outdoors use?
The LP / LPM series feature as standard protection class IP 65 (dust-tight and protected against water jets), which allows outdoor use without any problems.
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 LPM and LP 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 single-phase 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.
Tips & tricks: Lubrication of the chain
Regular lubrication of the chain can extend the service life by the factor 20 - 50. It is important to lubricate the chain also between the chain links. A commercially available lubrication can be used here.
Tips & tricks: Preventing diagonal pull
The diagonal pull of loads (> 4°) should be avoided, since the chain and the chain guide are excessively worn out in this way, which can affect the safety of the system.
Tips & tricks: Wrong running direction of the chain hoist
The electric chain hoist is electrically incorrectly connected and needs to be properly connected by authorised staff.
Tips & tricks: Trolley with plastic rollers
Should the standard steel rollers be too loud or should they transmit noise into the building, we recommend plastic rollers (up to maximum 1 250 kg). For more soundproofing solutions please contact our sales team.
Tips & tricks: Trolley with stainless rollers
In case of aggressive acids or alkalis in your working environment, we recommend a corrosion-resistant electric chain hoist and a trolley with corrosion-resistant rollers.
