The WJ80/80 material hoist is that the Shandong Province building scientific research institute designs that course surveying , studying all round , build the new erect carrying machine. producing exploitation from Guheng machinery, the perpendicularity being used for building structure main body the middle inside and outside fitting up material being under construction such as the queen who is over and old house fitting up being under construction broadly hoists (strictly prohibit from man-carrying jacking motor), Have resolved a tower crane being able to not material be hung transport to storey inner problem, also can accomplish the construction lifter the main body alone under the situation of not having tower machine; WJ80/80 material hoist price is cheap compared with the elevator being under construction, has higher function price ratio. Owe machine the structure simplicity , promotion and demotion safety , have the complete safeguard device , the safety working reliably , use the ideal building the middle being under construction , the high-effect perpendicularity being maintained going to the lavatory , being to transport machinery.
