Tons of Load, Micron Precision: Expertise in 390 Excavator Cylinders
The Caterpillar 390 is an indispensable powerhouse for the most demanding sites, from quarries to large-scale dam constructions. The agility and digging force of an excavator of this magnitude are maintained by the flawless pressure balance within its hydraulic cylinders. At Seçkin Makine, we manufacture the cylinders that drive every movement of the CAT 390 series to the highest engineering standards.
Critical Cylinder Groups for Operational Efficiency
An excavator's success in the field depends on the lossless transmission of hydraulic power. The main groups we produce include:
-
Boom Cylinders: They provide the primary lifting force of the machine, offering stability and power while lifting the heaviest blocks.
-
Stick Cylinders: Managing the digging depth and the arm's fore-and-aft movement; they require high resistance under constant load.
-
Bucket Cylinders: The source of the breakout force that allows the bucket to penetrate the toughest terrains.
-
Quick Coupler Cylinders: They minimize downtime in the field by speeding up attachment changes.
Why Seçkin Makine Manufacturing?
The cost of downtime for machines like the CAT 390 is extremely high. To prevent these costs, we base our production on the following criteria:
-
Forged Steel and Special Coatings: We apply hard chrome plating and special heat treatments to our cylinder rods to ensure high corrosion resistance.
-
Heavy-Duty Sealing Elements: We use wear-resistant seal kits that maintain integrity under high pressure and varying temperatures.
-
Dynamic Testing: Every single cylinder is subjected to static and dynamic leak tests at maximum operating pressure before being dispatched.
Seçkin Makine combines the power of the Caterpillar 390 with the precision of Turkish engineering to deliver uninterrupted performance to the field.
