What Are the Different Types of Overhead Cranes?

2025-06-12 09:47:48

Overhead cranes can vary so much in terms of specifications and configurations. No two crane builds are exactly alike! A crane that worked in a similar building structure, or similar lifting application, may not be the best crane for your facility or your application. So, selecting the right type of crane for your business is critical to maximizing efficiency, streamlining workflow, and getting the best bang for your buck. An overhead crane, commonly called a bridge crane, is a type of crane found in industrial environments. An overhead crane consists of two parallel rails seated on longitudinal I-beams attached to opposite steel columns by means of brackets. The traveling bridge spans the gap. the different types of overhead cranes including: Bridge Cranes Gantry Cranes Monorail Cranes Jib Cranes Workstation Cranes What is an Overhead Bridge Crane? An Overhead Bridge Crane is a type of material handling equipment that lifts and moves heavy loads within an industrial space, typically using a bridge-like structure that moves along overhead runways. It's characterized by its ability to move loads horizontally and vertically within the crane's operating area. Structure: The crane consists of a horizontal bridge, which is supported by and moves along elevated parallel runways built into the building's structure. Movement: A hoist trolley (the mechanism that lifts and lowers the load) travels along the bridge, allowing for controlled horizontal movement of the load. Operation: Bridge cranes can be operated manually, via a wired pendant station, or with wireless controls. Applications: They are commonly used in manufacturing facilities, warehouses, and other industrial settings for tasks like lifting and transporting heavy materials, loading and unloading trucks, and moving products between workstations. Types: Bridge cranes can be configured with either a single girder (one beam) or a double girder (two beams) design. Advantages: Overhead bridge cranes offer a wider range of motion and more flexibility compared to other overhead crane types, making them suitable for moving heavy loads in multiple directions. What is a Gantry Crane? A gantry crane is similar to a bridge crane, but instead of moving on suspended runways, the crane uses legs to support the bridge, trolley, and hoist. These legs travel on rails that are embedded in, or on top of the floor or ground structure. A gantry crane is ideal when you require a lightweight and quick knockdown crane for applications that require portability and corrosion resistance. They are also considered when there is a reason not to incorporate an overhead runway system and are most traditionally used in outdoor applications where full beams and columns can’t be installed, or they can be used below an existing bridge crane system. Gantry cranes are commonly found in shipyards, railyards, special construction sites like where a bridge is being built, or in places like steel mills where overhead room may be an issue. Gantry cranes come in a wide range of designs, including: Adjustable Gantries – used for warehousing applications requiring the movement of materials through aisles, doorways, around obstacles, and over or under obstructions. Welding and fabrication shops can use gantry cranes for lifting parts and equipment into position. Portable Gantries – used for plant maintenance applications requiring replacement and relocation of equipment and machinery. Service truck applications requiring quick knockdown for fast, easy movement to and from a work site. Track-Mounted Gantries – used for applications requiring lifting and moving heavy loads over a fixed route, either manually or motorized. Moving and lifting heavy materials doesn’t have to involve installing expensive equipment or permanently changing your facility. Gantry cranes do the job efficiently and economically and are ideal lifting solutions because: No permanent installation is required—making gantry cranes ideal if you rent or lease your facility Quick and easy assembly and tear-down Portable design allows for use in more than one facility or work area What is a Monorail Crane? Most commonly found in a production or assembly line, this type of crane uses a trolley to carry the hoist along a single path. Monorail cranes do not utilize a bridge or girder design—instead, the trolley is designed to connect to an I-beam, often already built into the ceiling structure, and runs along the flat surface (flange) on the bottom of the beam. They can also utilize a configured support structure as well. Material can be run back and forth in a straight line, or the rails can be designed with curves, branches, switches, and with changes in elevation. Monorail cranes follow a singular path and are designed for lifts that do not require the side-to-side trolley movement provided by the bridge in an overhead or gantry style crane. Monorail cranes are perfect for lifting applications where a full-blown crane design is not required. They’re a cost-effective and versatile solution for many assembly line and production applications. What is a Jib Crane? Jib cranes come in a number of different styles and types but do not utilize a runway or track system. They can be stand-alone or column / wall-mounted and offer a wide variety of capacities, heights, and spans. Jib cranes are space-saving, economical, and are ideal for jobs like maneuvering or moving items for assembly within a smaller radius. They can typically offer 180-360° of rotation, and even small ones can hoist several tons of material. The best way to determine what type of jib crane is best for your application is to consider the following: What type of operation or usage will this equipment see? What height clearances or spans are required in this work area? Is there available support structure available for mounting, or will this be a standalone unit—(floor, wall, and ceiling)? What other special options or considerations are required? What is the available budget for the system and installation? What is a Workstation Crane? Workstation cranes are designed to allow the operators an ergonomic means of moving or lifting loads with limited effort in a smaller size work area. Workstation cranes are typically lighter-duty systems—lifting materials from 150 lbs. up to 2 tons in capacity. They’re designed for repetitive lifting of loads, positioning of loads, increasing worker productivity and ease of work flow. They can be built and installed easily using a modular design for greater flexibility and do not require an existing support structure for installation.

How do cranes work?

2025-06-12 09:38:53

Cranes are believed to have been in use as early as 3000 BCE. The earliest of them, called ‘shadoof’, were used to lift water from lakes and rivers for irrigating farmlands in Egypt. It consisted of a pole with a bucket on one end that was counterbalanced on a fixed support. The Simple Crane In its simplest form, a crane consists of a lever and a pulley. Cranes at a fixed angle, with a single arm, were used in the early days to lift heavy loads. These days, modern cranes that can work from a few degrees angle to a nearly perpendicular position that can lift very heavy loads can be found everywhere, from construction sites to warehouses to seaports. Stationary as well as mobile cranes help to move cargo from one location to another easily. Generally, cranes are counterbalanced to prevent them from toppling forward with the weight being lifted. Some of them have projecting arms or legs that can be planted firmly to the ground to help maintain stability and distribute weight evenly. How are Shipping Containers Loaded and Unloaded? Cranes play a very vital role when it comes to lifting and stacking heavy objects in the port yard. They are also used to load heavy objects onto a ship. If we take a gantry crane that is more common in seaports, it has a main supporting framework called the gantry, a boom or a long arm that goes over the ship with a spreader and a cabin suspended over the main framework from where the operator controls the crane. Here, the spreader is a movable clasp that is used to grip and lift cargo containers from and onto a ship. Mobile cranes have trolleys that move on tracks along the quayside. There are rubber-tired gantry cranes as well. Containers are lifted from the ship and placed on truck beds or on the ground for reach stackers or forklift trucks to move them to their designated area. Port cranes are generally designed to lift weights ranging from 40 to 120 metric tons. A mechanism called ‘spreader’ is used to attach and lock onto the four corners of a shipping container to lift it for loading or unloading. It locks onto the corner castings of a container using a twist lock mechanism. Spreaders are designed to lift 20’, 40’, or 45’ containers. A single spreader can lift these containers separately or 2×20’ containers together. Double spreaders can lift single containers, 2×40’ or 45’, or 4×20’ containers in one move. Spreaders are used in different types of cranes to handle shipping containers. A crane may be diesel-powered or powered by electricity. However, most modern cranes are electric-powered. Separate high-powered motors are used to move the boom, gantry, trolley, and hoisting mechanism. The cranes used in seaports are generally classified as quay cranes and yard cranes. As their names suggest, quay cranes operate by the quayside, while yard cranes are found in the inner yards of the port.

Cranes are an essential part of any port. Without them, the transport of cargo would be effectively impossible. But you may be surprised at just how many different types and sizes of port cranes exist. This blog will explore these variations of port cranes and what differentiates them from each other. What is the primary function of a port crane? Port cranes serve a relatively simple, but critical, purpose: handling and transporting shipping containers to and from ships and throughout a terminal. This is true across all port cranes, regardless of the specific variant. Types of port cranes Most port cranes fall under the umbrella of gantry cranes. These are heavy duty cranes that are built on top of a gantry frame. Spreader Bars are suspended from the gantry and used to pick up containers by latching on to the corners of the containers via a standardized twist lock system. Among gantry cranes, there are a few main variations of crane. This blog will cover rubber-tired gantry (RTG) cranes, rail-mounted gantry (RMG) cranes, automatic stacking cranes (ASC) and ship to shore (STS) cranes. How to choose a port crane Selecting the right crane for your particular port is vital. Consider these key factors: Cargo Type Bulk Goods (Coal, Grain): Continuous unloaders, grab cranes. Containers: Ship-to-shore (STS), rail-mounted gantry (RMG) cranes. Heavy-Lift: Heavy-lift cranes with high capacity. Key takeaway: Match the crane to the primary cargo. Port Size & Layout Small Ports: Mobile harbor cranes (flexible, versatile). Large Ports: Specialized STS cranes (for large container ships). Consider: Quay length, water depth, vessel size, crane reach, and footprint. Automation Needs Fully Automated: Automated STS cranes, automated stacking cranes (ASCs) - for high efficiency and reduced labor. Manual Operation: May suffice for less demanding needs. Think long-term: Align automation with budget and efficiency goals.
