Description

Technical Field

[0001] The utility model relates to the technical field of equipment related to engineering services, in particular to a lifting device for engineering services. Background Art

[0002] Engineering services are mainly reflected in the entire life cycle of an engineering project, and its main stages are feasibility analysis, project establishment, survey, design, construction, operation, end of life and then entering the next cycle. Consulting services in the pre-design stage, budget services and bidding services in the survey and design stages, engineering contracting, material procurement, labor contracting, engineering equipment leasing, and even various services such as accommodation and meals in the construction stage, raw material procurement, finished product sales, transportation and logistics services in the operation stage, repair and maintenance in the middle of the life cycle, and disassembly and transformation services at the end of the life cycle. In engineering services, the lifting equipment used to lift objects is extremely important. In existing engineering services, stackers are generally used to complete the lifting. However, the placement part of the stacker is the fork. The fork can be inserted under the object to be lifted, and can also lift the objects placed on its surface. However, if the objects to be lifted are small and scattered or irregular, they generally need to be completed with the help of pallet tools; once there is no pallet tool, some stones or barreled mud in the engineering service cannot be placed firmly, and there is a risk of falling.
