Frequently Asked Questions (QZ 5t-32m-16m A8 Grab Crane Drawing Analysis)

Common technical questions on the 5t capacity, 32m span, 16m lifting height, four-rope double flap grab 2.5m³, full VFD, remote control, and 2-unit order.

1. What are the advantages of full VFD control on this grab crane?

Full VFD (Variable Frequency Drive) on all motions — hoisting, trolley travel, and crane travel — provides smooth acceleration and deceleration, precise grab positioning, reduced mechanical wear, and energy efficiency. This is especially valuable for bulk material handling where precise control and reliability are critical.

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 is a 2.5m³ four-rope double flap bucket, and the bulk material density is ~1.1 t/m³.

3. What is the significance of the M8/A8 duty class?

M8 (ISO A8) is a heavy-duty class, suitable for continuous operation with heavy loads and high frequency. This is appropriate for bulk material handling applications where the crane operates intensively throughout the workday.

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, with full VFD control on all motions.

5. What does the model designation "QZ 5t-32m-16m A8" mean?

QZ = Double Girder Grab Crane; "5t" = 5-ton capacity; "32m" = 32-meter span; "16m" = 16-meter max lifting height; "A8" = ISO A8 duty class.

6. What is the four-rope double flap grab suitable for?

The four-rope double flap grab bucket with 2.5m³ capacity and ~1.1 t/m³ material density is suitable for handling bulk materials such as coal, grain, sand, gravel, and other loose materials in industrial yards, ports, and storage facilities.
