Seals
The team at Challenge Europe have found that
alongside their core threaded fastener range,
there is a demand for sealing “O” rings on an
urgent basis – and consequently decided to
enhance stock levels to meet the need.
Common requirements for “O” rings come
in Nitrile (NBR), EPDM, Viton®, Silicone,
Polyurethane and Neoprene with many
others also called for to suit the needs of
practically every industrial sector.
Challenge Europe can support both
production line requirements and supply as
consumable items for manufacturing plant.

Indeed, any application where seals for liquids

and gasses are an essential requirement.

Challenge Europe stock standard metric and

imperial sizes to ensure that production lines

keep moving and maintenance operations can

proceed smoothly.

These “O” rings function as seals between

fixed faces in static assemblies or as dynamic

seals between moving components, e.g.

in cylinder and piston configurations or on

rotating shafts in valving equipment.

Back-up rings are also available in a range of

materials and styles.

Cranes
British crane rental company Coussens
Crane Hire, which is based in Bexhill-on-
Sea in East Sussex, has just added two new
Demag all terrain cranes to its fleet: Not
only a Demag® AC 60-3 with a 50-meter
main boom, but also a Demag® AC 100-4L
with a 59.4-meter main boom that can have
its reach extended with a 19-meter swing-
away jib, which the company also ordered.
Both cranes feature the innovative IC1-Plus
control system, which utilizes the maximum

available lifting capacities when working with

asymmetrical outrigger configurations in

tight space conditions, as well as a remote

control.

“The remote control is particularly

useful when it comes to lifts without an

unobstructed view,” explains Managing

Director Paul Coussens, who states that the

crucial factor that influenced his purchase

decision for the AC 100-4L was its compact

design: The crane is 2.55 meters wide, and

no other crane in the same capacity class

has a smaller width. He also considers the

Demag AC 60-3 all terrain crane to be the

ideal machine for lifting roof trusses, steel

girders, and concrete components at large

working radii or over and beyond obstacles.

“In addition, with its lifting capacity of up

to 60 tonnes, the AC 60-3 is also the right

choice for lifting heavy loads such as boats

at tight radii. This makes it a particularly

versatile unit for our purposes,” Paul

Coussens explains.
