30 Tons Double Girder Overhead Crane for a Steel Coil Yard

A 30 ton double girder overhead crane is the workhorse of a steel coil yard. It moves heavy coils from the unloading point to the storage area and feeds them to the processing lines, lifting at full rated load every cycle. The machine below is specified around that duty.

Steel coil yards store coils that typically weigh 10–30 tons each, and a full load can pass 40 ton. Work runs in multiple shifts: coils arrive by truck or rail, are stacked in the yard, then delivered to slitting, cut-to-length, pickling or packaging lines. The crane must lift repeatedly at 30 ton, set coils down squarely in narrow aisles and beside conveyor stations, and keep running shift after shift without downtime. That duty rules out a single-girder machine. The double girder design provides the stiffness to carry a wide coil lifting beam at 30 tons and keeps the hook travel steady over the full lifting height.

Key Specifications

Double Girder Overhead Crane for a Steel Coil Yard Features

• ◆ Double box girder construction with welded diaphragm plates gives torsional rigidity and limits deflection when lifting a full-width coil load.
• ◆ Coil tooling ready: works with a C-hook, coil lifting beam or motorized coil turner, so one crane covers unloading, stacking and line feeding.
• ◆ VFD drives on all motions provide soft start and stop; the load settles without impact, protecting coil edges and the plant floor.
• ◆ High-duty components — A6/A7-rated motors and brakes — are sized for continuous multi-shift handling, not occasional lifting.
• ◆ Anti-sway control keeps the hook steady at travel speed, shortening cycle time and reducing the risk of coil-to-coil collision in tight aisles.
• ◆ Full safety package: obmedzovač preťaženia, dual limit switches, anti-drop brake, buffers and rail clamp, plus an optional coil rotation interlock.
• ◆ Maintenance-friendly layout with centralized lubrication and replaceable wheel blocks simplifies inspection between shifts.

FAQ About Double Girder Overhead Crane for a Steel Coil Yard

Q1: Can the crane lift a coil directly without a beam?

A1: Nie. A C-hook or coil lifting beam is required to keep the coil horizontal and prevent edge damage. The crane and the beam are matched at 40 tons during design.

Q2: What span and lifting height are available?

A2: Both are custom to the building. Common spans are 22.5 m, 25.5 m and 31.5 m; lifting heights range from 8 m do 16 m.

Q3: Can it run in an outdoor coil yard?

A3: áno. With a rain-proof enclosure and corrosion protection it can operate outdoors; wind and temperature conditions are confirmed at the design stage.

Q4: What is the delivery and installation time?

A4: Typical delivery is 60–90 days after drawing confirmation. The supplier’s engineers can carry out installation and commissioning on site.
