Example: Painting the building: Parts' pictures Pedal-type suspended platform is a kind of lifting equipment for high altitude operation,being developed and manufactured solely by Shenyang HuaCai coating Co.,Ltd. in China.The product is designed uniquely and with novel structure,and the operator can lift up and down with the help of his leg’s strength,just like pedaling a bicycle,which can be locked automatically when not being pedaled.The suspended platform can be lifted up and dwon freely,and the speed can be controlled by the operator.During the lifting procedure,it can keep a stable state.The lifting height of the platform depends on the height set of wire rope.The structure of the platform is simple and reasonable and the inner design is scientific.The wire rope is in a direction of through the special structure in the equipment and transforms the external force into the towing power of machinery by negative force lock-control technology.There set three kinds of different safety brake structures on the platform,thus effectively guaranteeing the safety.As to suspended structure ,there are three categories in total for selection,i.e. scaffolding-type,jig-type,except for basically-equipped gib arm.Users can assemble the platform structure from 2 to 6 meters according to their needs.It is easy to be dismantled,stored and transported,espicially for the construction in the aspects of coating decoration,thermal-insulation,plastering and brick paste of high-rise buildings,and maintenance and cleaning of buildings.It is new mechanical equipment for high altitude operation.The product is divided into two varieties,i.e. double-person and single-person.
