防爆環鏈電動葫蘆工作條件：

環境溫度：-20℃～+40℃   

工作制度：中級JC25%   

重級：JC40%   

當中級工作制度電動葫蘆的起重量降低30%時，即為重級工作制度JC40%的電動葫蘆。   

重級工作制度JC40%的電動葫蘆是用在工作比較繁重，負載經常在額定值或要求安全系數較高的情況下

explosion-proof chain electric hoist safe and convenient. Explosion-proof chain electric hoist chain all use of low carbon steel material, explosion-proof chain electric hoist increased toughness and strength of the chain, guarantee the safety of working.

Explosion-proof chain electric hoist working conditions:

Ambient temperature: - 20 ℃ ~ + 40 ℃

Working system: intermediate JC25 %

Weight: JC40 %

When the intermediate working system of the electric hoist lifting weight reduced by 30%, the working system of the first level JC40 % of electric hoist.

JC40 % of heavy work system of the electric hoist is relatively heavy in work, load current in the case of rating or require higher safety coefficient
