Product Features of Galvanized Hoists
Four-rope Single-line Structure
- Dual load-bearing wire ropes share the lifting load jointly, reducing stress on single rope and greatly extending service life of steel wire ropes.
- All steel wires are arranged parallel in the same vertical plane, which prevents sling deflection during trolley travelling and enables precise positioning directly above narrow pickling tanks.
Low Headroom Compact Structure
- Perfectly suitable for pickling workshops and sites with limited track space, maximizing effective lifting height.
- Narrow overall dimension allows two hoists to run side by side closely on the same track, ideal for dense multi-station layout.
Industrial-grade Anti-corrosion Protection
- Adopts IP55 protection grade and Class F insulation grade.
- The shell is treated by shot blasting up to Sa2.5 standard and coated with epoxy zinc-rich anti-corrosion paint, effectively improving the service durability of galvanized hoists.
- Equipped with high-strength galvanized steel wire ropes featuring excellent corrosion resistance, which prolongs the overall service life and perfectly fits actual operating scenarios.
Applicable to Curved Tracks
- Optimized travelling mechanism and wheel sets fit circular and curved tracks well, enabling smooth passing through bends and realizing continuous workpiece handling throughout the whole process.
- No secondary hoisting or manual operation is required to greatly boost working efficiency. It also supports factory circular layout to cut civil construction costs.
Exclusive Customization Services
- Custom thermal insulation protection can be designed according to high-temperature environments to meet operation demands of different working stations.
- Custom anti-corrosion coatings, rated lifting capacity and lifting height are available to satisfy heavy-load and frequent start-stop working conditions.
- Various model solutions are provided to ensure stable operation in harsh galvanizing workshops and reduce subsequent maintenance costs.
Main Components of Galvanized Hoists
Galvanized hoists is professionally designed for harsh galvanizing environments. All core components are elaborately manufactured to deliver superior corrosion resistance, stable operation performance and long-lasting service life.
Common Application Scenarios of Galvanized Hoists
Acid Pickling Workshops
Used for lifting and transferring metal materials in acid pickling processes. The hoist is designed to withstand acid mist corrosion and ensure stable operation in harsh chemical environments.
Electroplating Workshops
Suitable for material handling between pickling tanks and electroplating tanks. Corrosion-resistant coatings and precise control systems enable reliable and efficient operation during frequent lifting cycles.
Chemical Industry
Applied in corrosive environments such as acid and alkali storage areas, reactors, and chemical processing lines. The hoist provides excellent corrosion protection and operational safety for heavy-duty lifting tasks.
Wastewater Treatment Plants
Used for lifting pumps, valves, pipelines, and maintenance equipment in humid and corrosive conditions. Its anti-corrosion structure ensures long-term durability and reliable maintenance operations.
Stainless Steel Wire Pickling
Designed for highly corrosive mixed-acid environments in stainless steel surface treatment lines. Special protective structures improve service life and maintain precise lifting performance.
Hot-Dip Galvanizing Production Lines
Widely used throughout the galvanizing process, including pickling, fluxing, drying, galvanizing, and cooling stages. The hoist is engineered to handle acid mist, high temperatures, frequent operation, and precise positioning for continuous production environments.
