Its defining structure resembles a squared-off doorway or portal, formed by two sturdy, vertically oriented legs or uprights connected rigidly at their tops by a single horizontal beam. This essential portal frame, typically crafted from durable steel tubing or structural steel profiles like square sections or I-beams and often finished in functional coats of industrial paint such as blue, grey, yellow, or red, rests securely on a base equipped with swiveling castors or wheels. Crucially, most of these castors feature integrated brakes to lock the crane solidly in place during lifting operations, and often a combination of fixed-direction wheels and swiveling ones manages movement and stability. The vertical legs frequently incorporate a clever telescoping or sleeve design, allowing for significant height adjustment through mechanisms like locking pins or bolts, enabling the crane to adapt to various working heights or low overhead environments, typically ranging from roughly one meter up to three meters. Spans between the legs are also manageable, generally one to five meters, sometimes adjustable by repositioning the legs themselves.Critical to its function is the lifting mechanism that traverses the entire length of the upper horizontal beam. This usually takes the form of either a manually operated chain hoist or a compact electric hoist, securely mounted onto a trolley carriage. The trolley itself is designed to roll smoothly along the flanges of the I-beam or dedicated tracks integrated into the crossbeam. This setup provides precise lateral positioning of the suspended load. The hoist, whether pulled by hand or controlled via pendant buttons, raises and lowers the load via its chain or wire rope hook assembly. While electric versions offer powered lifting and sometimes powered traversing of the trolley for effortless movement, manual versions rely entirely on human effort to pull the chain and push the trolley along the beam. This combination of rolling base and traversing hoist grants exceptional versatility, allowing operators to easily position the crane exactly where heavy items need to be lifted, moved within its frame span, and then relocated entirely to a new workspace or pushed aside for storage, maximizing floor space efficiency. Commonly seen in workshops, garages, laboratories, maintenance bays, warehouses for light-duty loading, and even home studios, these cranes are indispensable for tasks like handling motors, heavy equipment parts, large tools, machinery on repair stands, bulk materials, or aiding in assembly projects where fixed overhead cranes are impractical or unavailable, offering a practical and relatively affordable solution for manageable lifting requirements.Application Scenarios1:Light-Duty Material Handling:Enables safe lifting and moving of machinery parts, crates, molds, and palletized goods in workshops, warehouses, and loading areas, reducing manual labor risks.2:Equipment Maintenance & Repair:Essential for hoisting engines, transmissions, or heavy components during servicing in automotive garages and industrial repair facilities.3:Production Line Support:Positions bulky parts (e.g., metal frames, motor assemblies) onto assembly lines or workstations with precision, minimizing worker strain.4:Laboratory/Controlled Environment Handling:Safely transports delicate instruments, experimental setups, or sensitive materials in labs and cleanrooms with controlled movement.5:Confined Space Lifting:Replaces hazardous manual lifting in tight spaces (e.g., narrow aisles, underground vaults) where overhead cranes cannot operate.6:Mobile On-Demand Service:Provides temporary lifting capacity across multiple locations (work cells, machinery sites) via wheeled mobility, ideal for flexible workflows.Our Advantages1:Exceptional MobilityEquipped with lockable castors, it can be easily repositioned across workshops, warehouses, or job sites, providing lifting capability wherever needed-eliminating fixed installation constraints.2:Space-Saving DesignIts compact vertical footprint and absence of permanent supports maximize floor space utilization, making it ideal for crowded facilities with low ceilings or narrow aisles.3:Cost-Effective SolutionRequires no costly foundation work or structural modifications to buildings (unlike overhead cranes), offering significant savings on installation, energy, and maintenance.4:Enhanced Safety & ErgonomicsReduces worker strain and injury risks by mechanically lifting heavy loads (up to 10 tons), replacing error-prone manual handling or risky improvised lifting methods.5:Rapid Deployment & FlexibilitySimple bolt-free assembly allows setup within hours, while adjustable height/span adapts to diverse tasks-from palletizing to equipment repair-without specialized tools.6:Scalable Workflow IntegrationSupports modular operations; multiple units can service parallel workstations or be combined for larger projects, scaling with evolving production needs. Packaging & ShippingTo ensure safe and damage-free transportation, cranes must be securely packaged in heavy-duty wooden crates or steel frames, with critical components like hoists and girders disassembled if oversized and properly strapped. Electrical systems and sensitive parts should be wrapped in waterproof, anti-corrosion materials, while all packages must be clearly labeled with weight, center of gravity, and lifting points. During transit, components must be firmly fastened using chains or straps to prevent shifting, with special attention given to corrosion protection for sea freight and route planning for oversized shipments. These measures guarantee that cranes arrive in optimal condition for assembly and operation.FAQQ1: What's the informtion should l provide when inquiry?The more details or drawings, the better.
