Oildraulic was a hydraulic elevator system created by Automobile Rotary Lift Co. (Rotary Co.) in 1937, and was later produced by Dover and then ThyssenKrupp. It was credited as being the first modern hydraulic elevator.
Course of the Oildraulic's life
Automobile Rotary Lift Co. was the precursor to Dover Corp. In 1955, the name was changed from Automobile Rotary Lift Co. to Dover Corp. Dover had two divisions from the start; Rotary Lifts, to continue making automotive lifts, and Dover Corp. Elevator Division to make elevators.
Dover continued to manufacture Oildraulic elevators until 1999, when its elevator division was sold to Thyssen Elevator (at the time in merger with F. Krupp AG and eventually becoming thyssenkrupp). Oildraulic elevators were also sold overseas through Dover's overseas subsidiaries and third-party distributors (for example, in the UK, Oildraulic lifts were distributed by Dover's subsidiary Hammond & Champness and some installations here has to use Dover's Impulse fixtures, which are, nowadays, extremely hard to find outside U.S. and Canada).
Thyssen in the United States installed elevators under the "Thyssen Dover" name, but with Dover branding from 1999-2001. In 2001, the merger of Thyssen and Krupp was completed to make one company, ThyssenKrupp. Thyssen Dover was renamed "ThyssenKrupp" as was all of the other brands. The Oildraulic elevator system was then bought by ThyssenKrupp and continued to be produced until 2012. Since 2001, Oildraulic was no longer available overseas; it became an exclusive model in the United States and therefore it was only sold there.
In October of 2012, ThyssenKrupp announced that it would discontinued the Oildraulic system, in-favor of the new, eco-friendly, endura system. ThyssenKrupp continues to make traction and MRL elevators, along with the new endura hydraulic elevator.
The Dover/ThyssenKrupp Oildraulic is a holeless and holed/in ground hydraulic elevator system. The model of a Dover/Thyssen Dover/ThyssenKrupp Oildraulic elevator is the model's abbreviation or name first two numbers of capacity (example: "CTL 45" or "Continental 45" has a 4500 pounds capacity)
Rotary and Dover specifications (prior to the 1980s)
Not much is known about the specifications for Automobile Rotary and Dover Oildraulic elevators produced from the 1950s to the 1980s. At that time, Dover Oildraulic elevators were controlled using mechanical relays.
Dover specifications (1980s? - 1999)
These were the specifications before the Oildraulic model was acquired by ThyssenKrupp in the 2000s.
Dover's Oildraulic had 8 models, based on different applications, building types and conditions. They are CIM 20, CIM 25, CTL 45, CTL 50, FLW 21, MRQ 25, SVL 30, and SVL 35. CIM stands for Cimarron, CTL stands for Continental, FLW stands for Fleetwood, MRQ stands for Marquis, and SVL stands for Seville. The CIM 20/25 models are holeless hydraulic, while the rest are holed/in ground hydraulic. All of these models are controlled by the Dover DMC-I microprocessor controller. Door types were available in single speed, center opening and two speed telescoping, depending on the models. The doors are microprocessor controlled and DC powered, with limited door reversal and nudging. The standard signal fixtures used was Impulse, although other fixtures such as Custom Impulse, Traditional and Vandal Resistant could also be used as an option.
The Cimarron 20 was designed for buildings or areas where drilling a jack hole is difficult. They have a front-mounted cylinder that seldom needs more than a one-foot hole, which makes these elevators practical for areas with high water table or bedrock. The Cimaron 20 Oildraulic had a 2000 lbs. capacity and could travel up to four floors. The maximum travel distance is 32 feet. Speeds were available in 100, 115 and 135 feet per minute. Door type was only available in single speed (sliding) type.
The Cimarron 25 is similar to the Cimarron 20, except that it had a slightly bigger capacity at 2500 lbs, as well as a 30 feet maximum travel distance. Other than that, it shares the same other specifications as the Cimarron 20.
The Continental 45 Oildraulic elevator was designed primarily for hospitals and medical facilities. It could also be used for other buildings that required a combination of service and passenger elevator. It featured deep cars that could accommodate stretcher beds and wheelchair passengers. It could serve up to 7 floors (or 60 feet) and has a 4500 lbs. capacity. Speeds were available in 75, 100, 125, 150, 175 and 200 feet per minute. Door type was only available in two speed telescoping.
Continental 50 is similar to Continental 45 except that it had a bigger capacity than CTL 45, at 5000 lbs. Other than that, the CTL 50 shares the same other specifications as the CTL 45.
Fleetwood 21 was a model of Dover Oildraulic designed for all types of buildings such as offices, hotels, apartments, schools, etc. It is a compact and space-efficient elevator designed to carry passengers in wheelchairs. A rear entrance/door option was also available. FLW 21 could serve up to 7 floors or 60 feet. The capacity is 2100 lbs. Speeds were available in 75, 100, 125, 150, 175 and 200 feet per minute. Door type was only available in single speed sliding type.
Marquis 25 was a medium-sized elevator designed for offices, shopping malls, hotels, schools, etc. It was also available with a rear door/entrance option. MQR 25 had a 2500 pounds capacity. The maximum travel distance for MQR 25 was 60 feet (7 floors maximum). Speeds were available in 75, 100, 125, 150, 175 and 200 feet per minute. There were two door types available for this model; one is center opening and another one is single speed.
Seville 30 was a large-capacity elevator designed for office buildings, hospitals and other buildings with high traffics. Like all other models (except CIM 20 and 25), SVL 30 had a maximum serving floors up to 7 floors, or 60 feet. It was available with a 3000 pounds capacity. Speeds were available in 70, 100, 125, 150, 175 and 200 feet per minute. Door types were available in center opening or single speed.
Seville 35 is similar to Seville 30, except that it has a 3500 pounds capacity. Other than that, it shares the same other specifications as the SVL 30.
These specifications were the current specifications before the Oildraulic model was discontinued in 2012.
ThyssenKrupp Oildraulic had two series; the Advanced Material Elevator Evolution (AMEE) series and Conventional series. All ThyssenKrupp Oildraulic models are controlled by the TAC series microprocessor controllers; they are TAC20, TAC22 and TAC32. They are also equipped with ThyssenKrupp's patented "I-Series" valves, which controls the flow of oil to the the plunger and gives the exact supply necessary for smooth rides and gentle starts and stops. The signal fixtures used were either Impulse, Aurora, Signa4, Traditional or Vandal Resistant series.
Advanced Material Elevator Evolution (AMEE) series
