Un puente grúa es un dispositivo mecánico que se utiliza para levantar objetos pesados dentro de un espacio fijo. Se utiliza mucho en talleres, almacenes o espacios abiertos.
The girder of the bridge crane spans on a special track at a certain height and can move along the track in the span direction. It is equipped with a lifting device on the girder, most of which use a lifting trolley. The lifting device can move along the girder in the span direction. Because it looks like a metal bridge, it is called an overhead crane. In common parlance, bridge cranes are also called “Crane” or “Crane”.
1. Classification and uses of bridge cranes
Classification of grúas puente
There are many types of overhead cranes, which can be classified according to different methods.
1) According to different spreaders, they can be divided into hook cranes, grab cranes and electromagnetic suction cup cranes.
2) According to different uses, they can be divided into two categories: general overhead cranes and special overhead cranes. There are many forms of special overhead cranes, mainly including forging overhead cranes, casting overhead cranes, metallurgical overhead cranes, power station overhead cranes, explosion-proof overhead cranes, insulated overhead cranes, hanging beam overhead cranes, dual-purpose ( Three-purpose) bridge crane, large lifting height bridge crane, etc.
3) According to the structural form of the main beam, it can be divided into box structure overhead crane, truss structure overhead crane and tubular structure overhead crane. In addition, there are cranes with simple cross-section beams made of shaped steel (I-beam) and steel plates, called beam cranes. Beam cranes usually use electric hoists as lifting trolleys.
The purpose of bridge crane
Bridge cranes are widely used in various industrial enterprises, ports, warehouses, material yards, power stations and other places.
Different types of puentes grúa pórtico are suitable for lifting different types of heavy objects, and different spreaders are used according to specific requirements. Hook-type cranes are used to lift various heavy objects; grab-type cranes are used to lift various bulk items, such as coal, coke, sand, salt, etc.; electromagnetic chuck-type cranes are used to lift magnetically conductive metal materials. Such as section steel, steel plate, scrap steel, etc.
Dual-purpose or triple-purpose polipasto aéreo viga are designed to improve production efficiency. Their trolleys are equipped with convertible hooks, grab buckets or electromagnetic disks that can lift finished parts, bulk items or magnetically conductive metal materials. However, only one of these retrieval devices may be used each time a load is lifted.
Explosion-proof cranes are used for lifting heavy objects in workshops, warehouses and other places with flammable and explosive media. Electrical equipment and related devices on cranes are explosion-proof to prevent sparks from causing explosions. Insulation cranes are used to lift various finished items in the electrolysis workshop. Relevant parts of the Se vende puente grúa aéreo are equipped with reliable insulation devices to ensure safe operation.
Double trolley crane is a kind of mechanical equipment widely used in workshops, warehouses or open spaces, and is used to lift heavy objects in fixed spans.
