• Built-in self-locking function for high safety: The worm gear drive has reverse self-locking characteristics, preventing the crane from drifting or the boom from sliding down when stopped, eliminating the need for an additional brake and greatly improving operational safety.
• Large reduction ratio and high output torque: Achieves a large reduction ratio in a small volume, providing low-speed high-torque output to meet the slewing requirements under heavy-load conditions.
• Compact structure for easy installation: Small overall size and light weight, which can be directly integrated into the crane base, saving installation space and adapting to the compact layout of truck-mounted cranes.
• Smooth operation with low noise: The worm gear meshing drive has low impact and low noise, ensuring smooth and stable slewing action with high control precision.
• Applicable Equipment: 2-16 ton truck-mounted cranes, aerial work platforms, sanitation rotating equipment, small construction machinery, etc.
• Typical Models: Commonly used in truck-mounted cranes from brands like XCMG, Shimei, Feitao, with models such as SQS series reducers, HZ010C, etc., meeting the slewing drive requirements of cranes of different tonnages.
• Regularly check the lubricating oil level and quality of the reducer, and replace the gear oil according to working conditions to avoid wear caused by oil shortage.
• Check the meshing clearance between the output gear and the slewing bearing to prevent gear breakage or abnormal transmission noise.
• Check whether the seals are aging and leaking to prevent mud and water from entering the housing and causing corrosion.
• Avoid long-term overloaded slewing operations to prevent overheating and accelerated wear of the worm gear.
