Heavy Haul & Over-Dimensional Trucking
Engineered road transport for cargo too heavy, wide, long or tall for ordinary trucks — permitted, escorted and delivered safely across Central Asia and beyond.
Specialists in Oversized and Heavy Road Transport
When cargo exceeds the legal limits for standard road transport, every kilometre must be planned. Navigator Sea Land Limited delivers end-to-end heavy haul and over-dimensional (OOG / "negabarit") trucking for industrial machinery, energy equipment, mining assets and construction plant — from a single oversized crate to multi-hundred-tonne components.
Our team combines transport engineering with years of first-hand execution on Central Asian roads: long steppe distances, bridges with limited ratings, low power lines, seasonal load restrictions and multiple border regimes. We select the right equipment, secure the permits, engineer the route and supervise the move — so your cargo arrives on time, intact and in full compliance.
What Is Heavy Haul and Over-Dimensional Transport?
Heavy haul refers to loads whose gross weight or axle loads exceed the standard limits permitted on public roads. Over-dimensional (OOG) transport covers cargo that exceeds the legal width, height or length of a standard vehicle and load. Many project shipments are both.
These movements require special permits from road authorities in every country crossed, engineered route studies, specialised trailers that spread weight across many axles, and — depending on size — escort vehicles, police accompaniment and temporary removal of road obstacles. In Central Asia, where routes cross several jurisdictions and infrastructure varies widely, local knowledge is decisive.
Cargo We Move
Energy & Power
Power and distribution transformers, reactors, generators, gas and steam turbines, turbine rotors, switchgear houses.
Oil, Gas & Petrochemical
Pressure vessels, columns, heat exchangers, compressor skids, wellhead and drilling equipment, process modules.
Renewables & BESS
Wind turbine blades, towers and nacelles; BESS and inverter containers; solar substation equipment.
Mining & Metals
Crushers, SAG/ball mill shells, haul trucks, excavators, conveyor structures, kilns.
Construction & Cranes
Crawler and mobile crane components, counterweights, boom sections, tunnel boring equipment, bridge girders.
Industrial Machinery
Presses, rolling-mill stands, paper machine rolls, boilers, pre-fabricated steel structures.
Our Heavy Haul Equipment Range
Through our owned-partner and contracted fleet network across Kazakhstan, Uzbekistan and neighbouring countries, we deploy the configuration that best matches your cargo, route and site:
| Equipment | Best used for |
|---|---|
| Low-bed / low-loader semi-trailers (2–6 axles) | Machinery, tracked equipment and tall cargo needing reduced deck height |
| Step-deck and drop-deck trailers | Tall cargo on routes with height restrictions |
| Extendable flatbeds | Long items: pipes, beams, columns, tower sections |
| Hydraulic modular trailers (conventional axle lines) | Very heavy cargo; weight spread over many axle lines with hydraulic levelling and steering |
| Self-Propelled Modular Transporters (SPMT) | Ultra-heavy modules, precise manoeuvring, roll-on/roll-off at ports and sites |
| Girder-bridge / vessel-bridge trailers | Transformers and vessels where overall height must be minimised |
| Wind blade trailers and blade lifters | Rotor blades of 60–90 m+ on winding or hilly routes |
| Heavy prime movers (6x4, 8x4) in pull or push-pull | Traction for high gross combination weights and gradients |
| Escort and pilot vehicles | Warning, traffic control and route clearing |
| Jacking & skidding systems, mobile cranes | Loading, off-loading and set-down where cranes cannot reach |
Equipment Selection & Load Engineering
The safest and most economical move starts with the right configuration. For every heavy haul project our engineers evaluate:
- Cargo dimensions, weight, centre of gravity and designated lifting and lashing points.
- Gross combination weight and individual axle loads versus road and bridge limits.
- Trailer deck height, overall transport height and width against route clearances.
- Turning radii at junctions, roundabouts, rail crossings and site entrances.
- Bridge capacities and ground-bearing pressure at loading, unloading and parking areas.
- Gradients, road surface, seasonal conditions and available traction.
- Lashing and securing calculations and dunnage / cribbing design.
The outcome is a documented transport method statement — equipment configuration, route, schedule, lashing plan, escort plan and risk controls — shared with you and the authorities before any cargo moves.
Permits, Regulations and Route Management
Oversized and overweight road moves in Kazakhstan, Uzbekistan and other CIS countries require special permits and are subject to strict movement conditions. Navigator manages the entire compliance process:
Route Surveys
Physical survey with measurements of bridges, overpasses, power and telecom lines, junctions and pinch points; photo and video report.
Special Permits
Applications for oversize/overweight permits in each country crossed, including route approvals and bridge assessments.
Escorts & Police
Pilot cars, traffic management and police escort arranged as required by permit conditions.
Obstacle Management
Coordination with utilities and road owners for lifting power lines, removing signs, barriers or street furniture.
Movement Windows
Compliance with time-of-day, weekend, weather and seasonal (spring thaw) restrictions.
Border Crossings
Pre-arranged customs and transit procedures at Kazakhstan, Uzbekistan, Kyrgyzstan, China and Caspian borders.
Beyond the Road: Integrated OOG Solutions
Heavy haul is rarely a single-leg operation. We integrate road transport with Caspian heavy-lift and ro-ro vessels, CIS rail flat wagons and well wagons, and ocean break-bulk shipping — for example: European manufacturer → Poti or Baku → Caspian → Aktau → Atyrau / Tengiz, or Chinese factory → Khorgos → Kazakhstan / Uzbekistan project site. One plan, one team, one contract.
Oil & Gas
OOG Route: Tengiz to Baluchistan via China
Pioneered a multi-country route for oversized oilfield equipment from western Kazakhstan to Pakistan through the China Land Bridge and Khunjerab Pass.
Corridor: China Land Bridge
