Frequently Asked Questions (QZ 10t-22m-12m A6 Grab Bucket Overhead Crane Drawing Analysis)
Common technical questions on the 10t capacity, 22m span, 12m lifting height, U50 four-rope grab 3m³, full VFD, cabin control, and outdoor shed operation.
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 handling gypsum and cement additives where precise control and reliable operation are critical.
2. What is the significance of the 70% grab fill and 5-ton effective load?
The U50 grab bucket has a 3m³ capacity with a material density of ~1.7 t/m³. At 70% fill, the effective load is approximately 5 tons (3m³ × 1.7 t/m³ × 0.7 ≈ 3.57 t material + 4.273 t grab weight ≈ 7.8 t total, but the effective load is considered as 5 tons for design purposes). This provides a safety margin while ensuring efficient material handling.
3. What is the function of the 72m travel length?
The 72m travel length allows the crane to cover a long runway in an outdoor shed, making it suitable for large storage yards where gypsum and cement additives need to be transported over significant distances.
4. What are the power requirements for this grab crane?
3-phase, 415V, 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 10t-22m-12m A6" mean?
QZ = Double Girder Grab Crane; "10t" = 10-ton capacity; "22m" = 22-meter span; "12m" = 12-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 gypsum, cement additives, coal, ore, sand, and gravel. For this application, it is used for gypsum and cement additives with a density of ~1.7 t/m³.
7. Why is this crane designed for 0 to 55°C ambient temperature?
The crane is designed for outdoor shed installation where ambient temperatures can range from 0°C in winter to 55°C in summer. All components, including motors, VFDs, and hydraulic systems, are selected and configured to operate reliably across this temperature range.
