Sevencrane-designed semi-gantry crane put into service

Since the first 5t cantilever semi-gantry crane independently designed by Sevencrane was put into use, all performance indicators have been good and met the design requirements.

ElThe 1 ton wall mounted jib crane consists of a bracket, jib installation, swivel installation and electric hoist (electric chain hoist). The bracket is fixed on the wall or steel structure column and can be rotated according to user needs. The rotating part is divided into manual rotation and electric rotation. Electric hoists (electric chain hoists) are installed on cantilever rails and are used to lift heavy objects. Cantilever cranes are widely used in light and small lifting applications in mines, workshops, assembly lines, warehouses, and docks. The utility model has the advantages of novel structure, reasonableness, simplicity, convenient operation, sensitive rotation, light weight, and sensitive load movement. The operation of this machine is realized through the handle control button, which controls the lifting and horizontal walking of the sevencrane 1 ton wall mounted jib crane. cantilevered semi gantry crane has a span of 17 meters, a lifting height of 7 meters, and a rated lifting capacity of 5t. It adopts manual remote control and has an effective cantilever length of 5 meters, which greatly increases the working range of the semi portal crane. Cantilevers of this length are relatively rare in similar equipment, which puts higher requirements on the stability design of the semi goliath crane. In order to ensure the stiffness of the cantilever and meet the design requirements of lightweighting the whole machine, the cantilever grúa semipórtico is designed During the process, the technical department continuously optimized the structure based on the calculation results of finite element analysis software, determined a more reasonable and economical structural cross-section, and achieved the anti-overturning requirements of the entire machine by reasonably increasing the counterweight.

In order to save manufacturing costs, electrical engineers also independently completed the design, installation and debugging of the single girder semi gantry crane electrical control cabinet based on the electrical components in the company’s inventory.
