[ MANUFACTURING DIVISIONS ]

FIVE PRODUCTION UNITS.

UNIT 01

DESIGN & R&D

Full parametric 3D CAD modeling and Finite Element Analysis (FEA). Simulates real-time torsional stress, mast bending moments, and dynamic vibration under 60,000 lbs pullback loads before cutting a single steel plate.

CAPABILITY: ANSYS FEA · SOLIDWORKS CAD
UNIT 02

HEAVY FABRICATION

Robotic KUKA welding cells and high-precision CNC plasma cutters. Heavy structural channel masts, rigid box sections, and outrigger jack supports welded with multi-pass submerged arc procedures and ultrasonic crack inspection.

CAPABILITY: ROBOTIC MIG · ULTRASONIC NDT
UNIT 03

CNC MACHINE SHOP

High-precision horizontal boring mills, CNC heavy-duty lathes, and spline broaching equipment. Rotary drive shafts, swivel spalls, and gearbox adapters machined to micro-millimeter tolerances and induction-hardened.

CAPABILITY: ±0.005 MM TOLERANCE · INDUCTION
UNIT 04

HYDRAULIC ASSEMBLY

Dust-controlled assembly room dedicated to plumbing Rexroth variable-displacement piston pumps, Danfoss hydraulic motors, and Parker proportional valve banks. Every circuit undergoes full 350-bar leak and flow certification.

CAPABILITY: 350 BAR TESTBED · CLASS 8 CLEAN
UNIT 05

FINISHING & DISPATCH

Enclosed blast-cleaning booths using steel grit for SA 2.5 white-metal finish. Followed by two coats of high-build zinc epoxy primer and a tough marine-grade polyurethane finish formulated to resist desert sun and caustic saline mud.

CAPABILITY: SA 2.5 SHOT BLAST · PU FINISH
