A 45-ton dual purpose container spreader hook is a composite lifting attachment that combines a standard container spreader with a heavy-duty hook, letting operators switch quickly between “spreader mode” and “hook mode” on the same equipment. The spreader lifts standard…
Choosing a container spreader for a gantry crane takes more than lifting capacity. Buyers must also check load matching, upper-frame fit, power supply, twist-lock type, and control signals. A spreader is not a simple hook-on attachment — its frame, wiring,…
A container spreader locks and lifts containers through four twistlocks that insert into corner casting holes at the top of each container. Each twistlock rotates 90 degrees to hook the internal flange of the corner casting, creating a rigid link…
Thirty-five tons is the standard rated load for a 20-foot container spreader, fully suited to 20-foot container operations. This figure comes from the ISO 1496 maximum gross mass of 30,480 kg (about 30.5 tons) for 20-foot dry freight containers; after…
An ATEX-compliant petrochemical crane is an explosion-proof lifting unit built for oil refineries and chemical plants where flammable gases, vapors, or dusts are part of daily operations. Both electrical and mechanical parts carry explosion-proof certification, which means the equipment can…
A 50-ton production workshop should use a double-girder overhead crane with a 50-ton rated lifting capacity. But how do you right-size a factory crane for a 50-ton workshop without overspending on capacity you will never use or underspecifying a machine…
A warehouse crane can greatly reduce material handling costs by replacing forklift-based manual operations. In a typical 5,000 m² medium-sized warehouse, one 5–10 t single-girder overhead crane can replace 2–3 forklifts and 4–6 operators. The savings run about $ 30,000–$50,000…
Common port crane types include ship-to-shore cranes (STS), rubber-tyred gantry cranes (RTG), rail-mounted gantry cranes (RMG), mobile harbour cranes (MHC), and gantry cranes. STS cranes handle vessel-to-shore container work with single-box cycle times of about 60–90 seconds and rated capacities…
A railway crane is a specialized lifting machine that travels on rails under its own power or gets towed as part of a train. It mainly serves railway accident recovery, track laying, catenary maintenance, freight handling, and bridge/tunnel inspection. Its…
A custom crane is a non-standard lifting unit built for a specific application, parameter set, or special requirement. The main goal is to solve problems that off-the-shelf cranes cannot handle—complex working conditions, unusual site layouts, or specialized functional demands. Custom…
