30 ton double girder overhead crane for steel coil yards. Box girder, VFD control and coil lifting beam for reliable heavy coil handling.
الف 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.

30 tons double girder overhead crane for a steel coil yard
Steel coil yards store coils that typically weigh 10–30 tons each, and a full load can pass 40 تن. 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 تن, 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.

30 tons double girder overhead crane for a steel coil yard
Q1: Can the crane lift a coil directly without a beam?
A1: خیر. 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 مگس, 25.5 m and 31.5 مگس; lifting heights range from 8 م تا 16 مگس.
Q3: Can it run in an outdoor coil yard?
A3: بله. 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.
