Wall mounted jib cranes are space-saving material handling solutions that are fixed to a building's wall or structural column, featuring a rotating horizontal arm for lifting and moving loads within a specific area. They are ideal for individual workstations and production lines where floor space is limited, and they help reduce manual labor and improve productivity. Key Features & Benefits

• Space Efficiency: They require no floor space or special foundations, making them ideal for congested work areas.
• Rotation: Most models offer a rotation of up to 270° (wall-mounted) around the mounting point, providing wide area coverage, though some articulated versions can reach further around obstacles.
• Capacity & Reach: Load capacities typically range from a few hundred kilograms to several tons, with some models handling over 25 tons. Jib arm lengths (reach) can vary significantly, often up to 10 meters.
• Versatility: They can be used with various lifting devices, including manual hoists, electric chain hoists, rope hoists, and air balancers.
• Cost-Effective: They are an economical and practical solution for creating an independent workstation, often a lower-cost alternative to overhead cranes or forklifts for specific tasks. 

Types of Wall Mounted Jib CranesWall-mounted jib cranes come in different arm configurations based on the support structure: 

• Tie-Rod Supported Type: This is an economical design where a tie-rod supports the jib arm from above, making the structure lighter and ideal for high-ceiling applications where maximum floor space is a priority.
• Cantilever Type (Bottom or Full): This design provides the maximum hook path and is optimal when vertical space is a concern, such as in low-ceiling areas, as there is no support structure under the boom.
• Articulated Boom Type: These cranes feature a jointed arm, allowing operators to maneuver around obstacles and access hard-to-reach parts of the work area, offering greater flexibility than traditional rigid booms.

Key Technical Specifications

• Capacity: Typically 1 to 10 tons, with specialized units up to 20-32 tons.
• Lift Height: Generally 3 to 100 meters, depending on the application.
• Speed: Hoist speeds are usually 1–10 m/min, while travel speeds range from 5–50 m/min.
• Structure: Underhung systems utilizing H-beam or I-beam tracks.
• Power Supply: Usually 380V - 415V, 50Hz, 3-phase.
• Control: Pendant controls or radio remote control from floor level.
• Duty Class: Generally designed for A3-A4 class, with some models handling higher,

Electric Overhead Traveling (EOT) crane specifications vary significantly depending on the design type—Single Girder for light to medium loads or Double Girder for heavy-duty applications—and the specific operational environment. Key technical parameters include lifting capacity (SWL), span, lifting height, and duty

An Underslung EOT (Electric Overhead Traveling) Crane, also known as an underhung or suspension crane, is a specialized lifting system where the end trucks travel on the bottom flange of runway beams rather than on top. Core Characteristics

• Mounting: The crane is suspended from the building's roof structure or ceiling, eliminating the need for supportive floor columns.
• Headroom Efficiency: It is the ideal solution for facilities with low headroom or restricted vertical space, as it maximizes the lifting height within the available area.
• Capacity: Typically used for light to medium-duty applications, usually ranging from 0.5 to 10 tons, though some specialized models reach 20 tons.
• Types:
  • Single Girder: Most common for lighter loads; cost-effective and space-efficient.
  • Double Girder: Used for higher stability and slightly heavier lifting requirements. 

Key Advantages

• Space Saving: Frees up floor space by removing the need for vertical support columns.
• Side Approach: Allows the hoist to get closer to the side walls (better end approach) compared to top-running cranes.
• Interlocking: Multiple underslung cranes can be interlocked, allowing the hoist to transfer between different bridge systems.
• Cost: Generally cheaper to install in existing buildings if the roof can support the load, as it avoids expensive gantry structure modifications.
