不同软弱地基适用的施工机械液压蟹爪机构

Hydraulic Crab Mechanism for Construction Machinery Suitable to Different Soft Ground

为扩大履带式施工机械的应用范围，在已经专门阐述滩海沼泽地带施工车辆的辅助液压蟹爪机构的基础上（详见本刊１９９７年第２３卷第２期），根据软弱地基状况，进一步介绍适用不问土质的几种实用机构及其相对造价，提供了设计和制作依据。

To increase the application of track - type construction machinery, and based on the description of an auxiliary hydraulic crab mechanism for vehicles in the beach - shallow - water area (see full text on PEC Vol. 23 No. 2, 1997), a further introduction is given to a few types of practical mechanism suitable to different soft ground, and their manufacturing cost, providing design and fabrication basis.
