Types of electric hoist jib crane
Electric jib crane has different types and features. To get the most suitable jib crane, it is better to learn more details about jib cranes. The followings are about jib crane types features.
Free standing jib crane
This is the most common type of jib crane because they can be installed virtually anywhere including indoors or outdoors. Freestanding jib systems can be used underneath large bridge crane systems, or in open areas where they can support individual work cells. They can be used outdoors at marinas or loading docks, and indoors for machining and assembly operations where multiple jibs can be used in conjunction for staged operation.
Wall mounted jib crane
Wall-mounted jib crane systems can be used in individual bays, along structurally adequate walls or building support columns, or as a supplement to an existing monorail or overhead bridge crane. The main advantage of using a wall-mounted system is the space-savings that it offers. They don’t require any type of floor or foundation support, and they can also be installed very close to the underside of the lowest ceiling obstruction, providing maximum clearance both under and above the boom.
Cantilever: Wall-mounted cantilever jib cranes offer the greatest amount of clearance, above and below the boom, and have a full-cantilever design.
Tie-Rod Supported: This is the most economical means of providing hoist coverage along walls or building columns. A wall bracket and single tie-rod supports the boom to allow the hoist full travel along the length of the beam.
Wall traveling jib crane
This kind of jib crane is very flexible. The traveling rails are fixed on the wall, and the jib crane travel along the rail. In this way, traveling jib crane can prolong the service area and increase efficiency.
Components of electric hoist jib crane
Reach/Boom – the horizontal beam that the trolley travels back and forth on.
Mast/Pillar – the vertical beam used to support the boom on freestanding and mast systems.
Movable Hoist – the hoist is used to lift, position, and lower a load.
Trolley – the motion of the trolley can be manual, motorized, or pneumatic. The trolley carries the hoist, wire rope or chain, and the hook along the entire length of the boom.
Rotation – on free standing and mast type jib cranes, you can achieve 360°of boom rotation. On wall and column-mounted jib cranes, you can achieve 180-200°of rotation.
Electrification/Pneumatic Power – electric collector rings or pneumatic air lines can be added to the top or bottom of the mast to provide rotation assistance and allow for continuous 360° boom rotation.
Controls – on motorized or air-powered jib systems, you can use a push button controller to control the rotation of the boom, as well as the motion of the trolley and the lifting and lowering motion of the hoist. Multiple-speed or variable speed controls are available for the hoist and trolley.
Hook Height – How high can you or do you want to go with your lifts? You’ll need to know the lowest overhead obstruction to know how tall your jib crane can be.
Rotation Stop – if the crane is located close to a wall or other obstruction, a rotation stop will limit the crane’s motion before it collides with a nearby object.
Environmental Considerations – the components of the jib system can be galvanized to resist corrosion for outdoor applications. Also, special control enclosures can be designed for explosion proof applications, and other environments where heat, dust and dirt, or moisture may be a factor.
