Description

Technical Field

[0001] The utility model relates to the technical field of cargo transportation, in particular to a shuttle bus. Background Art

[0002] In the semiconductor manufacturing industry, OHT (Overhead Hoist Transport) systems are widely used for automated wafer transport. The OHT system uses rails and hoists suspended from the ceiling to transport wafers, thereby improving production efficiency and product quality. However, with the frequent use of OHT systems, regular maintenance and overhaul have become important links to ensure the normal operation of the system.

[0003] The traditional maintenance method of the OHT system relies on manual or simple mechanical devices to remove the OHT from the track for inspection and maintenance. However, this method is time-consuming and labor-intensive, and there are safety hazards. Especially under high load conditions, manual removal of the OHT system is likely to cause equipment damage or personal injury. Therefore, special equipment such as lifting equipment is required for maintenance. However, most of the current lifting equipment uses belt soft connections to lift the OHT system. The OHT system is prone to shaking when it descends to the preset position, making it difficult for operators to perform maintenance operations stably, increasing the danger of the operation.
