Frequently Asked Questions (QZ 10t-22.5m-30m A6 Grab Crane Drawing Analysis)
Common technical questions on the 10t capacity, 22.5m span, 30m lifting height, U50 four-rope grab 3m³, material density 1.0~2.0t/m³, and cabin control.
1. What are the advantages of cabin control on this grab crane?
Cabin control provides the operator with a clear view of the grab and the working area, allowing precise control during grab operation. It also protects the operator from harsh outdoor environments and offers a comfortable working position for long shifts.
2. What is the difference between crane gross weight and lifting weight?
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 4273 kg, and the material density is 1.0~2.0 t/m³.
3. What is the function of the 30m max lifting height?
The 30m max lifting height allows the crane to handle material at significant depths, making it suitable for deep storage pits, large industrial yards, and applications where material needs to be lifted from below ground level or from tall stockpiles.
4. What are the power requirements for this grab crane?
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.
5. What does the model designation "QZ 10t-22.5m-30m A6" mean?
QZ = Double Girder Grab Crane; "10t" = 10-ton capacity; "22.5m" = 22.5-meter span; "30m" = 30-meter max lifting height; "A6" = ISO A6 duty class.
6. What is the U50 grab bucket suitable for?
The U50 four-rope grab bucket with 3m³ capacity and 1.0~2.0 t/m³ material density is suitable for handling bulk materials such as coal, ore, sand, gravel, and other loose materials in industrial yards, ports, and storage facilities. The 4273 kg self-weight provides sufficient penetration force for dense materials.
