These cranes pair refined engineering with dependable manufacturing to deliver safe, efficient lifting indoors and outdoors. Light structures and low headroom reduce civil works while maximizing hook travel. Intelligent control and reliable components support stable uptime across equipment manufacturing, logistics, energy, and shipbuilding.
A full gantry runs on ground rails or tires with two legs supporting the bridge. A semi‑gantry uses one building‑supported runway and one ground‑running leg. Both provide high capacity without overhead runways, useful when roof reinforcement or overhead cranes are impractical.
✅Semi‑gantry: Share existing columns or walls, reduce steelwork, and keep one side clear for aisles or equipment.
✅Full gantry: Cover wide spans and open yards with maximum hook coverage. This design can be engineered for wind, corrosion, and precise positioning.
✅Lightweight structure and low headroom: Optimized beams cut dead weight and foundation load. Compact trolleys deliver extra lift height and lower energy use.
✅Safety and compliance: Built under strict quality control with traceability. Options include overload protection, limiters, anti‑collision, and condition checks. Environmental Management and explosion‑proof type test certificates are available; accuracy certificates on request.
✅Intelligent, efficient motion: Variable frequency drives, smooth acceleration, and optional anti‑sway improve throughput and reduce wear. Data‑ready controls support condition monitoring and predictive maintenance.
✅Custom engineering and lifecycle support: Spans, capacities, speeds, and protections matched to site conditions. Long‑term parts supply and service plans help manage total cost.
✅Single‑girder gantry crane: Cost‑efficient for moderate loads with compact headroom. Suitable for cells, warehouses, and maintenance bays.
Typical: capacity per project, span to site rails, maximized lift height, FEM/ISO duty per application.
✅Double‑girder gantry crane: For higher capacity, large spans, and rigorous duty. Supports auxiliary hoists, walkways, and platforms.
Typical: medium to heavy tonnage, wide yard coverage, long hook stroke, heavy process duty.
✅Semi‑gantry crane: One runway on the building, one ground rail. Saves steelwork and preserves aisles.
Typical: light to medium‑heavy capacity, asymmetric layouts, high hook with tailored runway levels.
✅Mobile/workstation options: Portable or workstation frames integrate with light crane systems for flexible tasks and changeovers.
✅Performance: Capacity from light duty to heavy process; coordinated hoist/long travel/cross travel speeds; span and lift height optimized by structural simulation; duty per FEM/ISO.
✅Hoisting/drives: Electric hoists, including explosion‑proof series, with inverters for smooth handling. Redundant brakes, hardened wheels, and precise gearboxes extend service life.
✅Protection/environment: Outdoor packages with IP‑rated enclosures, anti‑corrosion coatings, panel heaters, storm anchors, and wind‑proofing for coastal or high‑wind sites.
✅Safety packages: Load limiters, sway control, travel limits, anti‑collision, rail sweepers, optional load display and black box recorder.
✅Power: Festoon, conductor bars, or cable reels matched to travel paths. Soft‑start and energy recovery options help reduce peaks and wear.
✅Equipment manufacturing and automotive: Move assemblies, molds, and dies with precise positioning and low sway.
✅Energy, metallurgy, shipbuilding: Handle heavy modules, plates, and large fabrications with outdoor protection where needed.
✅Logistics, construction materials, paper & pulp: Load/unload containers, precast elements, and paper rolls with reliable cycles and anti‑collision in busy yards.
Pre‑engineering reduces disruption, and modular components speed erection and commissioning. Factory acceptance, on‑site calibration, and operator training support a smooth start. Condition‑based maintenance, remote support, and stocked parts help minimize downtime.
Use a portal crane when building runways are limited or outdoor coverage is required. Overhead cranes excel with strong roofs and linear coverage. Light crane systems and jib cranes complement localized handling; combine them for full‑site coverage.
Q: What information is needed for a quotation?
A: Provide capacity, span, lift height, duty cycle, environment (indoor/outdoor, wind/corrosion), power supply, and any explosion‑proof requirements.
Q: Can these cranes operate outdoors?
A: Yes. Specify wind class, IP rating, coatings, heaters, and storm anchors. Anti‑corrosion packages are available for coastal sites.
Q: Single‑girder or double‑girder?
A: Choose single‑girder for compact, cost‑efficient moderate loads. Use double‑girder for higher capacity, large spans, and frequent heavy cycles.
Q: Do you offer explosion‑proof options?
A: Yes. Certified explosion‑proof hoists are available. Selection depends on zone classification and process needs.
