Steel jib cranes equipped with pneumatic pumps, motors, and vacuum lifters represent a versatile solution for efficient sheet metal handling. By combining robust steel construction with pneumatic-driven vacuum technology, these systems enable precise lifting, maneuvering, and positioning of heavy metal sheets with minimal manual intervention. Their modular design allows integration of various lifter modules-ranging from compressed-air vacuum lifters to electric-motor-driven pumps-ensuring adaptability across production environments. Key benefits include enhanced operator ergonomics, reduced cycle times, improved safety, and compliance with international standards. Below is a detailed, 1500-word product introduction covering design, features, technical specifications, applications, and maintenance considerations.
Steel jib cranes provide a stable, slewing arm foundation for below-hook lifting attachments, offering a 360° range of motion and load capacities typically from 500 kg to 2 000 kg(, Konecranes). By pairing these cranes with pneumatic vacuum lifters-such as the compressed-air-powered F6A1000 for metal sheets-the system achieves instantaneous suction and release cycles, boosting throughput in cutting, bending, and welding operations().
Base & Pillar: Steel plates form the crane's foundation, anchored to the floor or wall. Pillar-mounted jibs support loads up to 2 000 kg with slewing ranges up to 300° (pillar) or 270° (wall)(Konecranes, Konecranes).
Jib Arm: I-beam or square-tube arms provide rigidity and low deflection; customizable lengths accommodate shop layouts(Konecranes).
Slewing & Bearings: Robust slewing bearings ensure smooth rotation; adjustable slewing resistance and limiters allow precise positioning every two degrees(Konecranes).
Protective Coatings: High-quality paint systems resist corrosion in harsh environments (e.g., welding shops)(vacuumlifter.en.made-in-china.com).
ISO-Certified Manufacturing: Suppliers like Viboo hold ISO 9001 and ISO 14001 certifications, guaranteeing consistent quality control from fabrication through assembly(cnviboo.en.made-in-china.com).
Compressed Air Vacuum Lifters: Devices like the Righetti F6A1000 utilize compressed air to generate vacuum, eliminating the need for electrical power at the lifter and enabling intrinsically safe operation in explosive atmospheres().
Oil-Free Pumps: Hero-Lift's pneumatic vacuum lifters incorporate oil-free vacuum pumps, reducing maintenance and contamination risks for sensitive sheet metal applications().
Vacuum Accumulators: Integrated vacuum accumulators store energy to maintain suction in case of air supply interruptions, ensuring load retention for several minutes and preventing accidental drops(vacuumlifter.en.made-in-china.com).
Dual-Power Systems: Kino Cranes offers vacuum lifters with AC-main and DC-backup power, enabling continuous operation during power outages and extended autonomous cycles for high-volume production lines(Kino Cranes).
Motorized Slewing: Electric motors can automate jib rotation for repetitive tasks, synchronized with lifter actuation for fully mechanized handling stations(Konecranes).
Capacity & Size: Models handle working loads from 500 kg up to 3 000 kg, with suction cup arrays customizable (e.g., 8-36 pads of 250 mm diameter) to match sheet dimensions up to 15 000 × 3 200 mm(Kino Cranes).
Tilting & Rotation: Pneumatic or electric actuators permit 90° tilting and 360° rotation of the sheet for ergonomic handling and precise alignment, crucial during welding or machining processes(Kino Cranes).
Safety Features: Closed‐circuit vacuum systems with non-return valves, low-vacuum alarms (audible and visual), and return-to-atmosphere release mechanisms enhance operator safety and minimize workpiece damage(Kino Cranes).
Control Methods: Cable pendant, radio remote, or PLC integration allow flexible operation modes to suit different workflows(Kino Cranes).
Vacuum Monitoring: Continuous vacuum level monitoring ensures reliable grip; any drop triggers alarms and halts operation automatically().
Suction Cup Variants: Silicone, PU, or spring-based cups adapt to textured or coated metal surfaces, ensuring uniform sealing without scratching(Kino Cranes).
