straddle carrier Basics in Container Terminals
A straddle carrier is a specialized vehicle designed to move and lift containers inside ports and yards. First, it carries the load by straddling the box and then lifting with a spreader, so operators can move containers and oversized loads efficiently. Second, this VEHICLE DESIGNED to lift ISO boxes replaces some fixed equipment. For clarity, the straddle carrier is a freight-carrying vehicle that carries one or more shipping containers under its frame. The carrier is a freight-carrying vehicle that carries boxes by running over them and lifting them from the top. This vehicle that carries its load underneath differs from a top like a conventional truck in how it picks up cargo.
In contrast, cranes and forklifts rely on fixed lifting points or short reach. A quay crane handles ship-to-shore transfers at the berth. By contrast, straddle carriers can move between quays and landside areas. They move without the assistance of cranes during many yard moves, and they can load and unload without the assistance of cranes or forklifts for certain container types. This reduces handovers, and it can speed cycles.
Standard lifting capacities vary. Many straddle carriers can lift standard ISO loads of 35 tons. Some designs carry double stack or stack containers up to four rows, so yards can reach greater density. Also, straddle carriers can stack containers up to four, which lets operators use height rather than more land. They typically travel at relatively low speeds, which helps safe manoeuvring in crowded yards. For terminal planners, the initial investment pays off with lower operating costs per lift over time.
Finally, if you want deeper guidance on stacking strategy, see our analysis of optimizing container stacking for yard operations for practical advice and metrics. This link explains how stacking choices affect throughput and density: optimizing container stacking for yard operations.
straddle and material handling Efficiency
The straddle design improves material handling in clear ways. First, the vehicle carries its load in a low, stable position, and that improves balance. Second, because the lifting apparatus travels with the vehicle, workers avoid repeated rigging steps that cranes require. Thus, operators reduce double handling and idle time.
Yard-layout flexibility increases too. A straddle can access ground-accessible lanes and move boxes between blocks. Consequently, terminal planners can create tighter lanes and denser stacks. For example, when teams reduce truck dwell at the gate, they shorten truck queues. Also, the spreader locks onto the container quickly, so precise control speeds placement. That makes straddle carriers great for quick reblocks and short-haul moves.
These machines cut time and labour. Studies show equipment that reduces handovers can increase throughput by measurable margins, and ports that adopt modular, mobile gear often report improved efficiency (Kalmarglobal on straddle carriers). In addition, recent modular designs shorten delivery and service time, which lowers downtime and maintenance costs. For more on optimizing yard operations across cranes and mobile fleets, read our piece on maximizing efficiency and optimization of yard operations in maritime container terminals: yard operations optimization.
Moreover, straddle carriers significantly reduce touches per container. They eliminate the need for intermediate forklifts in many moves. Also, because they can stack and move in one pass, teams report lower labour requirements. The design improves both MANOEUVRABILITY and maneuverability. Operators gain better sightlines and 360-degree visibility. For terminals and intermodal sites that handle mixed cargo, this advantage reduces errors and rework.

industrial straddle Solutions for oversized loads
Industrial straddle equipment extends the same principles beyond containers. For many yards, handles for oversized loads prove critical. Straddle carriers are also ideal for wind-turbine parts, precast concrete, and long steel sections. Their open frame and high-clearance design allow safe passage of bulky cargo. For example, operators can lift a blade or a precast concrete segment and move it without re-rigging on trailers. This reduces damage risk and streamlines lifting sequences.
Safety and load distribution systems matter here. Modern machines use spreader attachments and load sensors to balance heavy loads. They also incorporate safety interlocks and alarms. Therefore, teams can follow strict terminal safety rules while handling large items. In addition, 360-degree visibility and camera systems add another layer of precision and safety. These features produce dependable moves for heavy loads and long parts.
Examples show value. Wind-farm projects often require large components to move from quay to storage to truck. A straddle carrier can place those parts on a transport or stack them in a secure yard bay. This workflow reduces double handling and shortens project timelines. Also, straddle carriers can lift and place containers and oversized loads in the same shift. They thus create a cost-effective solution for mixed cargo terminals and industrial sites.
When specifying an industrial straddle, verify ISO standard spreaders and load charts. That helps ensure compatibility with containers and special rigging. In practice, pairing the right machine with a suitable spreader reduces incident risk and improves throughput. Finally, if you manage large projects, consider integrating telematics and optional remote control for complex lifts. That combination yields precise control and consistent results.

gerlinger and combi-sc Models Explained
Gerlinger’s lineup focuses on pragmatic performance. Gerlinger builds machines for yards that need dependable uptime and simple service. Their models target a mix of container handling and heavy load moves. For instance, Gerlinger offers units with reinforced frames and hydraulic systems tuned for frequent lifts. The manufacturer emphasizes spare-part availability and local service networks. That reduces lead times for repairs and replacement parts.
By contrast, the Combi-SC series emphasizes modularity and flexibility. The combi-sc family includes narrow and wide variants. Each variant supports different lifting heights and spreader interfaces. So, operators choose the right model for operations that require stacking, for example, containers per lane or long-height stacks. Combi-sc models come with telematics and optional remote control for safe night shifts. Also, the range includes diesel power choices and electrified alternatives like kalmar electric straddle options in the market.
Compare performance and delivery. Gerlinger typically promises robust local support and predictable delivery windows. Combi-sc aims for parts interchangeability and fast configuration. For many buyers, spare-part interchangeability matters more than top speed. That is because downtime costs can exceed fuel or diesel expenses. Plus, when carriers can move across roles, you need fewer specialized machines. The Combi-SC series supports this flexibility by offering broad customization and compatible service kits.
Finally, weigh training and certification. Both brands provide operator training so teams remain trained and certified. Also, consider how quickly a carrier would return to service after a repair. In many cases, modular parts reduce downtime. For details on balancing throughput with yard layout and equipment mix, see our article on optimizing container stowage plan and quay sequencing for integrated terminal flows: container stowage planning.
steering modes Optimisation and customer cases
Steering modes play a large role in yard efficiency. Most straddle carriers offer several steering modes: 2-wheel steer for straight driving, 4-wheel steer for tight turns, and crab steer for lateral moves. When operators switch modes, they gain better control of direction of travel and alignment. Consequently, they reduce repositioning moves and improve cycle time. Steering options also affect manoeuvrability in tight lanes and around active quay cranes.
Terminal safety improves with the right steering choice. Crab steer, for example, helps when placing a box into a tight row. Also, front and rear steering coordination helps stable lifts. Optional remote control adds the ability to make precise adjustments from a safe distance. For complex or hazardous lifts, teams use remote control and cameras to keep workers clear of pinch points. That practice improves safety and precision during lifts.
Real-world customer cases confirm this benefit. One operator replaced a mix of forklifts and older mobile gear with a small fleet of modern straddle carriers. They reduced truck turnaround and cut double handling. Another port used carriers to move ISO boxes directly from landside trucks to storage blocks, which lowered crane operations at the quay. These cases show that fleets tuned for steering modes can eliminate the need for extra handling equipment and improve throughput.
To explore practical metrics, note that the global straddle market is forecast to grow from about USD 1.2 billion in 2024, driven by port modernization and automation (market forecast). Finally, when you plan upgrades, consider integrated tech such as telematics, remote control, and yard AI to further reduce operating costs.
