The production process of Arkeng rack and pinion hoists include below steps.

  1. Design
  2. Analysis  
  3. Prototype Production
  4. Real Environment Tests
  5. Production  
  6. Final Checks and Product Tests  
  7. Shipment


Our engineers working in Arkeng technical department endeavour for a continuous improvement of our products in terms of firstly availability, safety, aesthetic and cost. At this stage, they transfer their intellectual creations  into CAD environment to perform the static and dynamic analyses with finite elements method. 


The designs to be transferred into computer are exposed to static load analysis, frequency (vibration) analysis, wind load strength analysis, material fatigue analysis, and the results are assessed.

Prototype Production

The product or the parts which are deemed appropriate as a result of the analysis are manufactured as samples first.

Real Environment Tests

The products or parts having prototypes are tested for real environment. Under the real environmental conditions, the mechanical behaviours of the materials in terms of static and dynamic loads are tested and the results of those tests determine if the product or the parts are appropriate for the production, as approved.


The one that is designed, produced as prototype and approved for production as a result of the tests in real environment is issued a production order. This order indicates the material characteristics, production figures, production technics, and the process starts.

Final Checks and Product Tests

Our products which are produced are controlled 100%. In these controls, the hoists are operated in our factory site to are applied all site dynamics and safety device tests subsequently becoming ready for the shipment with green label.


One of the greatest features of Arkeng lifts is that they are shipped as packaged. After all the tests, our lifts are loaded on the vehicles ready to be placed and raised at the work site. 






Metal Processing Workshops

Welded Production

The cabin, frame, mast, fasteners and other components of the Arkeng hoists are made from specially ordered raw material that is cut after delivery to our factory and combined with gas metal arc welding. Each production is continuously controlled within its own production process and the compatibility is enabled.

Metal Cutting                                 

Arkeng manufacture many materials on-site. Therefore, the main frame parts of the hoists, reducter materials, safety device (parachute) materials are manufactured in the metal cutting department with milling machine, cutting machine, lazer cutting machine, borwerk machine, radial drill, fellow, horizontal processing and others.

The reducers which we produce is helical conic gear type with I:16:82 cycle ratio, nodular cast iron, gear material of 8620 cementation steel, milling material of 4140 tempered steel, and the production is very special.

Similarly, the greatest feature of the safety device that is also produced in our site, is that it does not allow the hoist to move when it is active. Thus, out technical team search and find why it becomes active in order for our hoists to be used safely. In our safety devices, the material is selected with the highest strength without being fragile against impacted loads.

Dyeing Plant

All the parts of Arkeng lifts that requiring painting, are made on-site with its electrostatic powder dyeing plant . For that purpose, Arkeng constructed one of the largest dyeing ovens of the region with its engineers and this plant will also be presented for the use of others who need it.

Assembly Department

All the parts to be produced during the manufacturing process are assembled at the assembly department. The hoists to be assembled are connected to the test mechanism in the factory for the performance of all the tests. The hoists which have been tested are ready for the shipment order.
