After understanding the basic parameters of underhung cranes, we must also understand the metal structure frame structure of the bridge crane in detail. Let’s share it with you. The metal structure of underhung cranes is the skeleton of the crane, on which all mechanical and electrical equipment are distributed. It is the load-bearing structure of the crane and makes the crane form a whole mechanical equipment.

As a workshop crane, the cantilever jib crane is the ideal workstation crane for side-by-side workstations. They are responsible for transporting materials to various workstations and completing positioning tasks at the assembly station. They move up and down along the workshop wall on slides below the level of the overhead crane. SEVENCRANE cantilever jib cranes are the ideal workstation cranes for adjacent workshops. They can transport materials to various workstations and can also be used for positioning operations at assembly stations. This type of crane operates under an overhead crane on crane rails that run up and down the workshop walls.

Wall traveling jib cranes (also known as wall jib cranes) use bolted angle iron connections to fix the tripod bracket on a concrete wall or column. It can also be installed on machinery and equipment without occupying any ground space. The cantilever and bracket are hinged, with simple structure, convenient operation and large working space. The swing arm can be equipped with an electric hoist or a manual hoist to lift heavy objects. The electric or hand chain hoist runs linearly on the I-beam of the swing arm and lifts the heavy objects. The suspended heavy objects or self-prepared pull rings are pushed by manpower to realize the turnaround. It's important to note that the specific design and features of a wall traveling jib crane can vary depending on the manufacturer and the intended application. Consulting with a qualified crane supplier or engineer is recommended to ensure the selection and installation of the crane meet the specific requirements and comply with applicable safety standards.

A wall mounted jib crane, also known as a wall-mounted swing arm crane or wall-mounted cantilever crane, is a type of lifting equipment that is fixed to a wall or vertical surface. It is designed to provide a lifting and handling solution for materials and loads in industrial environments. The working principles and characteristics of wall-mounted jib cranes are generally described, and the specific design and application may vary depending on the manufacturer and usage scenarios. In actual use, a suitable wall-mounted jib crane should be selected according to the specific situation, and operated and maintained in accordance with the operating manual and safety regulations provided by the manufacturer.

Shipyard gantry crane, also known as gantry crane, is a common lifting equipment, mainly used for lifting items in warehouses, factories, ports, docks and other places. It is suitable for ship manufacturing, containers, cargo boxes, and other large items in ports, and has a wide range of uses. From its introduction to the present, many ports have been equipped with container gantry cranes. It consists of a robotic arm, a crane head, an electric motor and a control system.

First of all, gantry crane is also called gantry crane. It is mostly used for loading and unloading operations in outdoor cargo yards, material yards, and bulk cargoes. Its metal structure is like a door-shaped frame, with two legs installed under the main beam, which can walk directly on the track on the ground. There are overhanging cantilever beams at both ends of the main beam. The overall gantry crane has the characteristics of high site utilization, wide adaptability, large operating range, and strong versatility, and has been widely used.
