The difference between rack and pinion driven construction elevator and rope wheel driven construction lift
The car by the steel skeleton and the welding side eye woven mesh enclosure, on top of a lifting hoisting tower section with high standard. The gear rack drive system, motor, worm by end with disc brakes and small gear reducer, installed in the cabins in the steel base, rack mounted on the side of the car with tower truss, the small gear is engaged with the rack, after the motor is energized to drive the rotation of the pinion worm on the rack, which drives the car on the run. The car is equipped with guide wheel, the car on the main chord rod tower for linear movement without deflection. The car is provided on one side of the elevator driver seat, handles the elevator..
Construction elevator driven by rack and pinionThe gear rack driven by external construction elevator tower (rail frame), the car, driving mechanism, security mechanism and control system, enhance the jointing mechanism etc.. The tower is composed of welded space truss type standard joint welded by seamless steel tube. The standard section length is 1508 mm, and the standard section is connected with a bolt with a set of bolts. Main rod guide rail lifting device through cabins, rail and construction wall buildings in rachel. The non attachment height of the tower is 5.5 to 12 M.
Construction elevator is also called "man and goods" elevator. It is a vertical lifting machine which is installed outside the building and used to transport construction personnel and construction equipment during construction. It is one of the most important machinery in vertical construction of high-rise building. It has been recognized as one of the key equipment for high-rise building construction.Construction elevator is divided into gear rack drive and steel rope pulley drive two kinds. The former is divided into a single van and two van, which can be used as counterweight, and also not suitable for counterweight. The construction elevator has the single tower type and the Twin Towers frame type, our country mainly uses the single tower type.
