Frequently Asked Questions (QZ 10t-25.5m-25m A5 Grab Crane Drawing Analysis)
Common technical questions on the 10t capacity, 25.5m span, 25m lifting height, four-rope grab 1.5m³, finished coal 4.5t/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 environments and offers a comfortable working position for long shifts, which is especially important for finished coal handling.
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 4700 kg, and the material density is ~4.5 t/m³ (finished coal).
3. Why is the crane travel speed so high at 89.1 m/min?
The high crane travel speed of 89.1 m/min allows for rapid positioning along the runway, significantly improving operational efficiency in large coal yards where the crane needs to cover long distances quickly between loading and unloading points.
4. What are the power requirements for this grab crane?
3-phase, 400V, 50Hz. The lifting motors (2 × 37 kW YZR280S-10), trolley motor (5.5 kW YZR160M1-6), and crane travel motors (2 × 11 kW YZR160L-6) all run on this configuration.
5. What does the model designation "QZ 10t-25.5m-25m A5" mean?
QZ = Double Girder Grab Crane; "10t" = 10-ton capacity; "25.5m" = 25.5-meter span; "25m" = 25-meter lifting height; "A5" = ISO A5 duty class.
6. What is the four-rope grab bucket suitable for?
The four-rope grab bucket with 1.5m³ capacity and ~4.5 t/m³ material density is suitable for handling finished coal and other dense bulk materials. The 4700 kg self-weight provides sufficient penetration force for dense materials.
