The NS-CSB 2x2 Crane Spreader Beam is 2 metres in length and has SWL of 2 tonnes. These qualities make spreader lifting beams well-suited to lighter, shorter span lifts that have a small headroom requirement, such as in smaller manufacturing shops or storage facilities. Optional oblong can be added for large crane hooks. One crane attachment point for both lifting and upending. Bearing included for easy rotation to unroll cable. The main benefit of spreader beam is the substantially reduced headroom required to perform the lift. Model RL - Reel Lifter Rugged construction to lift and upend reels. Crane Spreader Beams consist of a long beam that converts the lifting load into a bending moment through the beam. This is a much less efficient use of material, and as a result, spreader beams are in general heavier than spreader bars. This requires a machine to cut and bend plate steel but allows you to make the channel any height (for exactly the required strength) and doesn’t require welding.2 Tonne Crane Spreader Beam 2 Metres Crane Spreader Beams, spreader bars and lifting beams are very similar devices in common use in almost every industry. These devices have very similar functions they allow a single crane to lift loads from multiple locations, to spread out the load and provide balance to the lift. A personal favorite of mine is to make lifting beams out of two formed channels that bolt together. Lifting beams give you the flexibility to get creative with the design a bit more than spreader bars. Lifting beams on the other hand are heavier but simpler requiring at minimum an I-beam which can be purchased along with a couple lugs welded on it. All of these process require a special machine or technique to manufacture. If you currently have a requirement for a spreader beam within your workplace, get in touch with our team on 01952 586 626 or email to find. Spreader bars will require pins, holes drilled in long tubing and a tubing selection that can slide in each other ( Stocking Spreader Bar Material). Our bespoke approach means every crane spreader bar we produce is made to order letting us fully customise it around your specific lifting requirement.

ManufacturingĪ bit needs to be said about building telescopic spreader bars vs lifting beams since each comes with its own challenges. When your hook height is limited as much as indoor cranes and you don’t need to transport the beam to the worksite every day it makes sense to use a lifting beam not a spreader bar. So when would you want to use a lifting beam? Lifting beams are commonly used for indoor shop cranes. The length of of the beam plays a huge roll in this calculation and the difference is sizes becomes increasingly more apparent as the spread increases. Building the beam strong enough to cope with this bending moment means lifting beams are heavier than spreader bars for an equivalent spread and capacity. When youre looking for crane hire companies in Perth, its not always enough to go for a company with the. However, because the transverse loads are not balancing through the top rigging like on a spreader bar you end up with a bending moment going through the bar. This allows you to lift your load a lot higher on a given crane using a lifting beam. This is because there is no top rigging and connecting your crane directly to the beam via the top lug eliminates the wasted height that the rigging takes up. In the mobile crane world this distinction is really important as carrying rigging out to site can be expensive and constrained by what they can fit on the crane or truck.Ī lifting beam is used when hook height and clearance are important. This allows spreader bars to become 2-3 times larger than the collapsed length allowing the user to have a much more versatile lifting device. of the purchase order) by means of weights and mobile crane with load cell. By constructing the spreader bar using hollow structural steel material you can get two or more pieces to slide inside each other. Single lifting beam, H lifting beam, lifting beam with duplex sling. The second difference is that spreader bars can easily made to be telescopic. This upper rigging comes at a cost for the equipment but also requires a lot more hook height on a crane to lift a given load. The downside of spreader bars is that they require upper rigging. This effect makes spreader bars very efficient at transferring loads and have a much higher capacity then lifting beams for their given size. Our bespoke approach means every crane spreader bar we produce is made to order letting us fully customise it around your specific lifting requirement. A spreader bar has a very elegant mathematical solution that eliminates opposing loads causing it to act like a pure column. The main difference between the two comes down to the engineering.
