Our Range Of Jib Crane Options
A Jib crane comes in many formats and Cranes Direct can offer you a wide range of Jib cranes for sale. We include our own custom made cranes manufactured here on site, to suit your lifting/hoisting needs/specifications. We are able to produce floor mounted, column mounted and wall mounted versions with either under or over bracing. Cranes Direct can also supply and fit 360 degree rotating variants as well as double arm models and articulated arm jibs. All comply to BS standards (BS7333/BS2853).
Swing Jib Cranes
A Jib crane may also be referred to as a swing Jib crane or slewing jib crane. They are a type of crane which typically consists of a supporting beam or column to which a slewing / swinging jib arm or boom is attached. Together with lifting accessories such as a hoisting device and beam trolley they enable the lifting, lowering and moving of heavy loads within a specific area. The lifting area will be restricted to the reach and range of slew/rotation of the boom. These are commonly used in the majority of industrial settings, warehouses, dockyards and within the construction industry. There are many benefits to using a Jib crane.
Jib cranes usually have a hand powered/manual rotation whereby they move in an arc, up to 360 degrees. The load can also be hand traversed along the beam by means of a trolley. However it is possible to have electric rotation and traverse movements if required. The hand powered/manual function uses a push and pull motion to rotate the jib arm and to move the load across the arm. The lifting and lowering of the load is usually done by means of a hoist, either manually or electrically powered. We are able to supply and fit electric hoists, as well as manual hoists, and any other lifting equipment you may need. A jib cranes arm doesn’t have to swing; it can also be manufactured in a Fixed Position.
Jib Crane Mounting Options
There are different ways of mounting the Jib crane products which we can manufacture and/or supply. The range includes; wall mounted, column/pillar mounted, floor mounted (also called free standing jib cranes).
The wall mounted option is usually bolted to a brick wall. This can only be done if the wall is deemed structurally sound and capable of withstanding the load. Specialist consultation may be necessary to ensure the structures are fit for purpose. Wall mounting is usually considered for lifting lighter loads up to 500kg. When there is no floor space available for a floor mounted model or suitable columns available.
Column or Pillar Mounted
Column or pillar mounted models are bolted and/or strapped to a brick column or steel support pillar within the buildings existing structure. These models take up no valuable floor space but can lift heavier weights that a wall mounted crane. In fact safe working loads of up to 3000kg are achievable with a column or pillar mounted slewing jib crane. Structural engineers may need to be consulted to test that the structure is able to take the strain.
Floor Mounted or Free Standing Jib Crane Models
Commonly called floor mounted or free standing jib cranes. They use very heavy duty bolts to secure them to the floor. Because of this it is essential that the floor or foundations are solid and stable and are able to take the weight of both the crane and the loads that will be lifted. In some cases the foundations may need inspecting and testing by a qualified person to assess the strength and stability. Although floor mounting takes up some floor space the main benefit is the ability to lift heavier loads – up to 3000kg. They can also offer a wider range of slewing options as they do not commonly have walls or pillars hindering the slew.
Jib Crane Bracing
All of the above cranes need to be stable and structurally sound (may need additional assessment) and can be manufactured with under or over braced jib arms.
Under Braced Jib Crane
An under braced frame work incorporates a steel support beam from the main, side column to the jib arm. This offers essential support for those heavy loads. Because the under brace is sited under the jib arm the crane to be fitted right up to roof level giving the advantage of gaining the maximum possible height of lift.
Over Braced Jib Crane
The over braced system incorporates a similar support beam, but unlike the under braced version the brace is fitted above the arm. Whilst this will lower the height of lift slightly it will maximize the lifting height under the beam. It will also maximize the travel span across the beam. Over bracing will give you maximum travel up to the upright side frames.
360 DEGREE SLEWING JIB CRANES, MOBILE JIB CRANES AND MORE
We can also supply 360 degree slewing Jib cranes, articulated Jibs and Jibs with powered rotation, from leading manufacturers. The 360 degree slewing model does as its name intends, the arm can fully rotate around its column. An articulated arm model enables easy manoeuvring around obstacles which can’t be moved.
CHOOSING THE RIGHT ONE:
Due to the fact that these types of cranes come in numerous variations, careful consideration should be made to all aspects to ensure you get the most well suited crane for its intended applications.
Things to consider;
- Size: height and span/radius
- Lifting Capacity
- Mounting: wall, column or floor
- Bracing: under-braced or over-braced (over-braced gives more room to travel across the beam, under-braced is ideal for lower headroom areas)
- Range of slew / rotation – typically 270 or 360 degrees
- Manual or powered rotation
- Additional equipment, i.e. trolley and lifting hoist

COMMISSIONING & INSTALLING:
Whatever type you choose, Cranes Direct can offer the full service, from custom building your bespoke crane to your own specifications or supplying a specialist Jib crane to delivering, installing and load testing your new crane to ensure it follows all safety regulations and protocols.
The stability and safety of your crane highly depends on its foundations or supports and should be assessed to ensure they can withstand the superimposed forces which will be applied by the crane and the loads it lifts. Floor foundations may need reinforcing, and column mounted cranes will need preventative measures to be taken to prevent the jib from sliding down.
