PROBLEM TO BE SOLVED: To curb increase in the cost of the driving section with the rack-and- pinion type elevator for construction work growing increasingly larger. SOLUTION: Two output gears 26-1, 26-2 are attached to one driving shaft 18, two pinions 28-1, 28-2 are arranged to engage with a rack 13, the two pinions 28-1, 28-2 and the two output gears 26-1, 26-2 are linked to each other via idle gears 27-1, 27-2, and the two pinions 28-1, 28-2 are driven by the output of the single driving shaft 18, simultaneously and at the same torque. |
