ZQ Crane Gearbox Overview
The crane gearbox is primarily used in industries such as lifting, mining, general chemicals, textiles, and light industry. It is suitable under the following conditions:
- The circumferential speed of the gearbox’s gear drive does not exceed 4 meters per second.
- The speed of the gearbox’s high-speed shaft is limited to a maximum of 1500 revolutions per minute.
- The gearbox is designed for both forward and reverse operation. When equipped with a backstop, the direction is determined by looking at the output shaft end.
- The operating temperature of the gearbox ranges from -40°C to +40°C.
- The gearbox offers nine different gear ratios, nine configuration types, and three types of low-speed shaft ends.
