Out‑of‑Gauge (OOG) Transportation

When cargo refuses to fit the box, we engineer the route—Silk Road rails, Gulf ports, and precision permits.

OOG for China–Iran: Built for the Unconventional

In markets where standard containers dominate, oversized cargo—turbine blades, refinery modules, press lines, yachts—demands bespoke thinking. RBGL designs end‑to‑end OOG moves across China–Iran corridors using heavy‑lift gear, specialized trailers, engineered rail routes, and watertight compliance.

From Shenzhen, Guangzhou, Shanghai and inland hubs like Chongqing, to Iranian gateways Bandar Abbas, Chabahar and inland destinations Tehran, Isfahan, Mashhad, we choreograph permits, escorts, axle loads, and transshipment with zero surprises.

What is Out‑of‑Gauge (OOG) Transport?

OOG covers cargo exceeding standard container dimensions (20/40 ft length, 8 ft width, 8.5 ft height). These loads require tailored handling—flat racks, open tops, low‑bed trailers, modular transporters, cranes, and route engineering.

Typical OOG Cargo

Industrial machinery and press lines
Construction vehicles and cranes
Wind turbine blades, nacelles, towers
Yachts and large boats
Refinery modules and heat exchangers
Aircraft components and heavy tooling

Preferred Equipment

Flat racks & open‑top containers
Extendable low‑bed and multi‑axle trailers
Self‑propelled modular transporters (SPMT)
Hydraulic jacks, gantry cranes, heavy‑lift cranes
Custom crating, lashing, and lifting frames

Key Challenges on China–Iran Corridors

Route Engineering: Bridge clearances, tunnel profiles, gradients, and axle loads across Xinjiang, Central Asia, and Iranian highways.
Regulatory & Permits: Provincial permits in China, transit permissions via Khorgos/Alashankou, Iranian abnormal load approvals, escorts, and curfews.
Multimodal Handoffs: Rail–road–sea transitions at Urumqi, Aktau, Bandar Abbas, and Chabahar with synchronized lifting windows.
Customs & Compliance: HS code accuracy, sanctions‑aware documentation, letters of exemption, and project cargo declarations.
Public Safety & Scheduling: Night moves, convoy management, police coordination, and urban passage timing.
Cost Control: Heavy‑lift gear, escorts, permits, and detours—optimized via precise planning and load sharing.

Technology We Deploy

Advanced route planning with clearance and axle load modeling
Modular trailers and hydraulic lift systems for complex geometries
Real‑time GPS/telematics for convoy tracking and incident response
Digital twins for lift plans, lashing schemes, and risk mitigation

Sustainability

Route optimization to reduce fuel burn and emissions
Fuel‑efficient tractors and maintained fleets
Consolidated project moves where feasible
Reusable crating, lifting frames, and lashing materials

Case Study: 68‑Tonne Turbine Module — Shenzhen to Tehran

Background: A power project required a 68‑tonne turbine module (12.8m × 4.1m × 3.6m) moved from Shenzhen to Tehran.

Challenges: Multimodal transitions, tunnel/bridge clearances, axle load limits, permits across borders, synchronized heavy‑lift windows.

Execution:

Pre‑survey and engineered lift plan with hydraulic jacks and spreader beams
Road to port in China → sea to Bandar Abbas → road convoy to Tehran
Police escorts, night transits, and staged stops for inspections
Customs documentation aligned to HS codes and project cargo exemptions

Outcome: Delivered on schedule with zero damage—precision planning and disciplined compliance at every handoff.

“In OOG logistics, size is a constraint—precision is the advantage.”
