Heavy‑duty material handling within port terminals, energy‑storage megafactories and industrial yards imposes strict requirements on lifting capacity‑to‑weight ratio, site adaptability, emission performance and operational compliance. Traditional gantry cranes and mobile truck cranes are frequently restricted by foundation requirements, site clearance limits and special‑equipment regulatory obligations. As a flexible travelling lifting solution, Kitanocrane multi‑functional straddle carriers deliver optimized performance for container transfer, energy‑storage module turnover and oversized‑component hoisting operations.
Core Product Portfolio & Application Boundaries
Kitanocrane has developed serial straddle carrier models covering 35 t‑80 t rated lifting capacity, segmented into energy‑storage dedicated variants, diesel‑powered standard units, energy‑storage container straddle carriers and full‑battery electric container straddle carriers.
The 35‑ton energy‑storage straddle carrier is purpose‑built for factory‑internal energy‑storage cabinet logistics. It achieves 5 km/h travelling speed, 3 m/min lifting speed, and matched gradeability parameters for frequent short‑distance shuttle tasks inside manufacturing workshops. The standard 35 t version adopts mainstream Cummins or Weichai off‑road engines, supports manual steering and optional remote‑control operation, with an approximate deadweight of 20 t excluding spreader assemblies, targeting general‑purpose heavy‑lifting scenarios.
For port‑side heavy‑container workflows, 60‑80 t energy‑storage straddle carriers are configured with oversized‑load spreaders to accommodate non‑standard heavy containers. The all‑electric 35‑80 t container straddle carrier adopts lithium‑iron‑phosphate battery packs, realizing zero local exhaust emissions. This variant fits indoor enclosed workshops and low‑carbon industrial parks where emission‑control standards are stringent.
Key Technical Design Highlights
Structural simulation serves as the foundation of equipment reliability. Finite‑element analysis combined with multi‑body dynamic simulation verifies stress distribution and fatigue life of all steel structural components. The whole‑machine coating follows harbour‑environment anti‑corrosion specifications, adopting multi‑layer primer‑intermediate‑topcoat surface treatment to resist salt spray and outdoor weathering. Extra‑wide solid rubber tyres reduce ground wheel pressure, enabling stable operation on uneven, unpaved or semi‑hardened yard surfaces.
The vehicle implements CAN‑bus distributed electric control architecture. Core hardware includes SYMC controllers, Pepperl+Fuchs sensors and Amphenol high‑reliability connectors. Real‑time data of travelling status, hydraulic pressure, battery status and fault codes are visualized via the on‑board HMI terminal, supporting condition monitoring and predictive maintenance.
Hydrostatic travelling drive provides stepless speed adjustment for smooth start‑stop and transition between lifting and travelling actions. Integrated side‑shift spreader positioning and anti‑tilt protection systems mitigate operational risks during offset‑loading conditions. Hydraulic lever control minimizes component failure points and lowers site‑side maintenance workload.
Operational & Compliance Advantages
Field‑tested cycle performance reaches roughly 10 lifting cycles per hour, with support for inclined loading and dumping operations unavailable for many conventional cranes. Unit equipment can access indoor workshops, expanding usable working space for wind‑power towers, tank vessels, prefabricated structural parts and modular energy‑storage products.
From a regulatory perspective, straddle carriers fall outside special‑equipment scope according to relevant national provisions. This eliminates mandatory annual inspection requirements and removes special‑equipment certification obligations for on‑site operators, effectively lowering long‑term operational overhead for asset owners.
Complementing the straddle‑carrier product line, Kitanocrane’s SPMT self‑propelled modular transporters adopt narrow‑body modular architecture. Multi‑unit soft‑hard coupling supports combined transportation up to 20 000 t total payload, covering ultra‑heavy transport assignments such as offshore engineering modules.
Field deployments span energy‑storage, new‑energy, port and heavy‑chemical industries across domestic and overseas projects. For sites constrained by fixed‑crane foundation limits or high compliance costs, flexible straddle‑carrier solutions represent a viable technical alternative.
