Common technical questions on the 5t capacity, 22m span, 12m lifting height, GP412 four-rope grab, material density 2.0t/m³, and cabin control.
Cabin control provides the operator with a clear view of the grab and the working area, allowing precise control during slag catching and bulk material handling. It also protects the operator from the outdoor environment and offers a comfortable working position for long shifts.
Crane gross weight does not include the grab weight — it is the weight of the crane structure itself. Lifting weight includes the grab weight plus the material being lifted. For this crane, the grab unit weight is 1300 kg, and the material density is ~2.0 t/m³.
The 72m travel length allows the crane to cover a long runway, making it suitable for large industrial yards where material needs to be transported over significant distances. This is particularly useful for bulk material handling and storage applications.
3-phase, 400V, 50Hz. The lifting motors (2 × 22 kW), trolley motor (1.5 kW), and crane travel motors (2 × 2.2 kW) all run on this configuration.
QZ = Double Girder Grab Crane; "5t" = 5-ton capacity; "22m" = 22-meter span; "12m" = 12-meter max lifting height; "A6" = ISO A6 duty class.
The GP412 four-rope grab bucket with 1.2m³ capacity and ~2.0 t/m³ material density is suitable for handling bulk materials such as slag, gravel, sand, and other loose materials in industrial yards and storage facilities.
