Indoor cranes, including bridge cranes, gantry cranes, jib cranes, and KBK workstation overhead cranes, operate within enclosed buildings to maximize space usage and workflow efficiency. Crane systems, including ceiling-mounted workstations and portable compact gantry cranes, are built for precise lifting capabilities, spans, and job cycles.
Indoor Crane Overview
Indoor cranes are hoisting mechanisms that have been put within buildings. They reduce the need for mobile cranes or forklifts in repetitive lifting jobs, freeing up floor space and decreasing equipment congestion. Common indoor crane classifications include:
1. Bridge Cranes
Bridge cranes operate on two parallel runway beams that are affixed to a building’s framework. A bridge beam spans those runways and carries a hoist trolley, enabling loads to be lifted and transported across the full width of a bay. These cranes accommodate capacities ranging from a few tons up to several hundred tons, making them suitable for heavy‑fabrication shops, shipyards, and large assembly lines. Installation involves mounting runway beams to supporting columns or walls and may require structural reinforcement and civil work to integrate the system into the facility.
2. Gantry Cranes
Gantry cranes share the basic configuration of bridge cranes but support the runway on freestanding legs rather than relying on overhead beams. The legs travel on rails embedded in the floor or on powered wheels, allowing the entire crane to move within or between work areas. Span and height are often adjustable, which helps match the crane dimensions to specific load requirements. Because they do not depend on existing building structures, gantry cranes are well suited for outdoor yards, temporary lifting stations, and workshops lacking ceiling‑mounted rails.
3. Jib Cranes
A jib crane features a horizontal arm (jib) that pivots around a vertical mast or wall‑mounted bracket. The hoist trolley runs along the length of the jib, providing localized lifting within the radius of the arm’s rotation, which typically spans 180° to 360°. Jib cranes require minimal installation effort and occupy a small footprint, making them practical for machine‑loading zones, light assembly cells, and small dock doors. Their lift capacity and range are limited compared with bridge or gantry cranes, so they are best suited for point‑to‑point handling at individual workstations.
Indoor Bridge Cranes
Indoor bridge cranes—often called overhead or EOT cranes—run on runway beams mounted to building columns or ceiling structures. Available models include:
Indoor Gantry Crane
Gantry cranes rest on freestanding legs that carry a horizontal beam across rails or powered wheels on the facility floor, eliminating the need for overhead runway structures. Because they do not rely on ceiling support, they can be installed in workshops, warehouses or outdoor yards where existing buildings lack the required load‑bearing capacity. The entire crane can travel between workstations or be shifted to new locations, making it suitable for tasks that demand flexibility in lift position.
Portable Small Gantry Crane
Constructed from extruded aluminum or high‑strength steel, portable gantry cranes with1‑ 10 ton lifting capacity strike a balance between durability and ease of handling. The reduced structural weight allows a single operator to roll the crane along its floor rails. After use, the legs fold inward to a compact profile, freeing up workspace in maintenance bays or small‑batch production areas. With options for battery‑powered or manual movement, these cranes can be redeployed across multiple tasks without requiring permanent power hookups or structural alterations.

Semi Gantry Crane
Semi‑gantry cranes anchor one runway beam to the building’s structure while supporting the opposite beam on freestanding legs that travel on floor rails or wheels. This hybrid layout blends features of bridge and gantry cranes, allowing one side of the span to rely on existing ceiling support and the other to function independently. These cranes are often installed in foundries or forging shops where one side of the workspace cannot bear the weight of a full bridge system. By using a single overhead runway, operators can span heavy molds, castings, or forged parts across workstations without extensive roof reinforcement.

Indoor Gantry Crane
A jib crane is a type of crane that supports a movable crane by attaching a cantilever or boom. They are versatile and have varying lifting capacities. Suitable for applications such as workstations, workshops, repair shops and more. Yuantai mainly offers the following selectable cantilever cranes.
