I. Profile
1.1, Pneumatic hoist is the most optimum lifting device in the world. It has been widely used in industrially developed countries, for it takes the following advantages over motor hoists.
First, the pneumatic hoist cannot generate electric spark, so it completely solves the anti-explosive problem.
Explosion-proof grade: Ⅰ Hazardous area, including ⅡC, Group T5 and below.
Second, the pneumatic hoist uses the 100% work system, so as to make the required conditions for high-efficient continuous jobs.
Third, the pneumatic hoist sees a fast operating speed which is 2-3 times more than the motor hoist, and the former can present non polar variable speed.
Fourth, the pneumatic hoist features endurance on acid, alkaline, steam and high-powder dust.
Fifth, the pneumatic hoist has small size and easily operation. It is only 1/3~1/8 of the weight of a motor hoist whose specification is same.
1.2, Based on the abovementioned characteristics, the pneumatic hoist is widely used in the areas of petroleum, chemical industry, coal, textile, machinery production, ship and aship and ammunition.
