MANUAL OR POWERED - Rigid Arm Knock-down Counterbalance Floor Crane

Very similar in design to the pivot arm style knock down crane except fitted with an adjustable rigid jib lifting arm with safe working loads up to 2000kg!

The big advantage of this type of design is that it can be used with either a hand hoist or an electric wire rope hoist for lifting materials much greater heights, for example a standard floor crane would most commonly be used for lifting equipment off the floor in a workshop etc where as this is more suitable for  lifting from below ground level, like pump well maintenance / lift shaft working / between floors on a building or for building maintenance (working from the roof of a building to raise materials or install new / replacement windows)

Knock Down means  a modular design that can be dismantled/disassembled after use and the after transportation to a new location can be quickly and simply rebuilt.

Note: The pictures shown are our artists impression only and are only indicative of our capability. (for display purposes only) All cranes are made individually and the the design may be subject to change according to your required specification; the pictures are not to scale, general arrangement drawings will be issued for approval on receipt of your order.

Advantages of the knock down design are:

• Reduced weight
• Less manual handling problems
• More compact design
• Can be set-up in locations that a standard counterweight floor crane simply could not because it purely would not be possible to get it there!

The weights shown her counterbalance the weight of the load being lifted by the jib / hook. The number and net weight depends on the SWL of the the crane. It is possible to shorten the chassis / frame of the mobile crane though this would involve more weights.

Floor Cranes With Spark Resistant Features / Explosion proof.

For Floor cranes to be used in potentially explosive areas / atmospheres such as Zone 1 or 2, SELS can include any anti-sparking features that our customers specify - this will increase its anti-sparking properties and therefore make the crane more suitable for use in a potentially explosive environment!

SELS will not to take the responsibility of supplying our floor cranes described as 'spark proof' as this is ‘too broad’ a term. We believe that total compliance is probably impossible because of the mechanical operation and movement of a floor crane; i.e. we cannot offer a 100% guarantee that no part of the assembly is capable of generating a spark which could ignite a flame!  IE: SELS will supply / manufacture cranes with anti sparking features to our customer’s requirements though will not certified them as sparkproof / explosion proof. Our cranes have been successfully supplied to customers in the offshore Oil and Gas industry in the UK on this basis.

Optional Features and Accessories
