Rack & Pinion Elevators

What is a Rack and Pinion Elevator?

GEDA USA’s rack and pinion elevators set the global standard for safe, and reliable vertical transportation of personnel and cargo in a variety of industrial applications. GEDA Rack & Pinion elevators are typically installed in structures such as grain silos, bridge towers, underground facilities, dams, power plants, cement plants, offshore platforms, refineries, and petrochemical plants.

The elevator car is equipped with a drive assembly located on top of the roof platform, and the elevator power is provided by an electric motor (s) drive shaft driving a pinion gear. Each pinion gear operates on a stationary rack connected to a supported tower, allowing the car to be driven up or down on command. An electric multiple-disc brake on the motor is used to stop the car travel.

GEDA rack & pinion drive elevators are also equipped with our patented, independent over-speed safety device, consisting of a governor-operated brake and separate pinion operating on the same rack. This totally automatic safety device operates independently of the elevator’s brake system.

GEDA rack and pinion elevator systems can be manufactured with various cab sizes, capacities and control options that include a variable frequency drive system. The VFD maintains control of the motor, providing the maximum amount of motor developed torque through all ranges of operation, and allows for a smooth start and stop, and achieves landing level accuracy when used with an encoder system.

Rack and Pinion Elevator Standards

GEDA’s product line of industrial elevators, transport platforms, and construction hoists are ANSI code compliant and meet stringent U.S., European, and international quality and safety standards. In addition, GEDA has been certified to meet DIN ISO 9001:2015 quality standards, DIN EN ISO 14001 environmental management and OHSAS 18001 occupational health and safety. We are also a proud member of the German Engineering Federation (VDMA), and the Committee of European Construction Equipment (CECE)

Proven to increase productivity and safety for facility owners and crew managers, GEDA USA rack and pinion systems provide a competitive advantage over traditional traction-style elevators. Each unit can be installed on building and structure exteriors, allowing for expanded production space. In addition, there is no machine room required, no hoistway required, and no overhead loads necessary. Steel support sizes are reduced, and installation can be completed quickly and more cost effectively than conventional elevators. In addition, each state-of-the-art elevator also allows for frequent inspections and provides a safe means of evacuation during emergency situations.
