HYDRAULIC TONGS BEAM 25t
Hydraulic tongs beam is designed for handling with
round blooms 410 mm of length 3000 - 6500 mm.
Beam is fitted with two tongs pairs, driven by recti-linear hydromotors.
Each tongs pair is driven independently that secures safe bearing of all
tongs pairs on the load and it means its reliable gripping. The mutual
synchronization of each tongs pair is performed by mechanical cinematic
chain.
Tongs parts, which are in contact with hot load, are designed as
exchangeable from the reasons of the increased wear.
Electromechanical system informs crane operator by means of signal lamps
located in cabin about mutual position of beam and load, i.e. about number
of blooms that are to be gripped by tongs.

The immediate state of all important
systems of beam is signalled to operator's cabin. Beam control system is
protected against accidental opening of tongs during load transport.
Hydraulic unit, which is located on beam body, is the source of pressure
liquid. All components of hydraulic circuit are protected against heat
radiation. The tongs beam is controlled by operator from cabin without
assistance of service on the floor.
Further the tongs beam is fitted with hooks for suspending of load magnet
and socket for its power supply connection. Power supply to the tongs beam
is performed from trolley frame.
