A gantry crane is a type of overhead hoist that is typically mounted on rails. Rails offer optimal support for the crane’s load, and rail mounted gantry cranes are found in shipyards, steel yards, and locomotive industries. They can be powered by electricity or steam, and the runners associated with them can be mounted on factory ceilings. The enclosed runners ensure effective grips. Gantry cranes can lift up to a ton of weight, and they can be rented or purchased for larger projects.
Cantilever Structure
Cantilever structure is a part of the main beam of the gantry crane(grua de portico), and extends beyond the width of the track below it. This type of structure is typically used for production operations, while finished products are transported, loaded, transferred, and discharged outside the span. Because of this, it is not affected by normal production operations. When choosing a gantry crane, you should consider several factors, including the application and the size of the products.
Load Capacity
When purchasing a gantry crane, you should consider how much weight the system will carry. Most gantry cranes are designed for high-volume lifts, and the maximum load capacity is approximately 1,000 pounds. They are ideally suited for general manufacturing, fabrication, and yard applications. The duty cycle of a gantry crane(grua portico birrail)’s components will determine how long they will last. A gantry’s design should also take into account foot traffic and other elements of the work area.
Operation
There are several steps involved in the operation of a gantry crane. First, the crane operator must switch on the crane’s main electrical power supply before allowing it to start working. This is done by alternatingly switching on the switch-disconnector switch and the emergency switch. Next, the driver should apply voltage to the crane’s protective panel, which should have a control green light. After that, the operator must check whether the handwheels and the controller handles are installed in zero positions. The driver must then turn on the linear contactor in the protective panel, accompanied by a characteristic click when the shaft is turned.
Components
A gantry crane consists of girders or beams that span a span of space, parallel to the ground. This type of crane(grua portico monorriel) has a range of sizes, ranging from small single girder models to large double girder types. Gantry cranes are designed with many different components, grouped into structural, electrical, and mechanical categories. Their components include the girder or beams, which carry the load, the hoist, and the crane drive.
Variations
One type of gantry crane is a single-leg type. Single-leg gantries have a single movable leg on the ground and an overhead end truck mounted on an I-beam. Single-leg gantries have dual motors: one to drive the wheels along the floor, while the other powers the overhead end truck. These cranes are often used in warehouses and other spaces where space is limited.
Applications
Gantry cranes are used for a variety of industrial applications. They are also called portal cranes. The word portal refers to the workspace of the crane. Many industrial facilities utilize gantry cranes for the handling of heavy objects. These cranes can be portable or stationary depending on the needs of the business. They are also useful for lifting heavy items. You can find a gantry crane in most warehouses, so there is no need to hire a professional to use one. Reference: https://aicrane.cl/
