1. Overall Design: The entire machine adopts a highly modular and compact design, primarily consisting of the following core components:
2. Low-Headroom Lifting Mechanism: It features a planetary winch structure and is mounted onto the trolley via connecting plates. The entire lifting mechanism is designed to be sunken, ensuring that the highest point of the whole machine does not exceed the height of the trolley end carriage.
3. Traveling Trolley: It is equipped with a specialized wave gear wheel assembly and is generally designed with a dual-drive configuration.

Product Uses
1. Low-Headroom Factories and Restricted Spaces: Specifically designed to solve the problem of limited overhead space in old factory renovations or newly built workshops, where conventional cranes cannot be installed.
2. Precision Manufacturing and Assembly: Suitable for workstations in industries such as automotive manufacturing, aerospace, and mechanical processing that require frequent lifting, precise positioning, and smooth operation.
3. Warehousing and Logistics Handling: Paired with double-girder overhead cranes or hoist gantry cranes, it enables efficient material transfer and stacking operations in warehouses and docks.
Product Operate Guide
1. Standardized Operation: Strictly adhere to the rated load capacity; overloading and diagonal pulling are strictly prohibited. Fully utilize the variable frequency speed control characteristics to ensure smooth starting and stopping, avoiding severe swaying of heavy loads.
2. Daily Inspection: Before daily operations, test whether the limit switches, emergency stop buttons, and safety monitoring systems are sensitive and effective; observe the wire rope for any broken wires, crushing, or severe rust.
3. Periodic Maintenance: Regularly check the brake clearance and the wear condition of the brake pads; inspect the oil level and sealing of the reducer; clear any foreign objects from the track and the trolley wheels.
4. Abnormality Handling: If abnormal noise, vibration, or system alarms occur during operation, stop the machine immediately for investigation; operating the equipment with faults or privately short-circuiting safety protection devices is strictly prohibited.
FAQ
1. What causes severe swaying when the ultra-low headroom trolley travels on the track?
Answer: This is usually caused by misalignment at the track joints, uneven wear of the traveling wheels, or improper setting of frequency converter parameters. It is recommended to stop the machine immediately to check the track flatness and whether the connection bolts are loose. If the mechanical components are normal, professional personnel should be contacted to recalibrate the acceleration and deceleration parameters of the frequency converter.
2. What should be done if the lifting mechanism experiences hook slipping under full load, posing a safety hazard?
Answer: Hook slipping is mostly caused by the wear of the electromagnetic disc brake or excessive brake clearance. Operations must be stopped immediately to check whether the thickness of the brake pads is below the set limit value. Although European-style brakes feature automatic clearance adjustment, if the wear reaches the scrapping standard, the brake pads must be replaced immediately to ensure safety.
3. How to handle frequent errors or failure to start in the equipment's safety monitoring system?
Answer: First, check the fault codes displayed on the human-machine interface (such as overcurrent, overheating, limit switch triggering, etc.). Inspect whether the aviation socket interfaces are loose and whether the cable protective corrugated pipes are damaged, which could lead to short circuits. It is strictly prohibited to forcibly reset the system before identifying the root cause; targeted troubleshooting must be conducted based on the fault prompts.
4. Under what conditions must the wire rope be scrapped and replaced?
Answer: The wire rope must be immediately scrapped and replaced if it shows severe wear, the number of broken wires exceeds the specified standards, has knots or deformation, or is severely rusted. Daily maintenance should ensure a uniform film of lubricating grease on the wire rope surface to avoid dry friction, thereby extending its service life.
5、How to further extend the service life of this equipment and reduce maintenance costs?
Answer: In daily use, frequent inching operations and overloading should be avoided. Keep the equipment clean and regularly check the electrical components (such as the ablation condition of contactor contacts). Due to the modular design of this equipment, if certain parts are damaged, standard interchangeable parts can be used for direct replacement, which significantly reduces the difficulty and cost of maintenance.
