GENERAL INFORMATION
The Vela barrier is an ideal solution for controlling traffic
movement in: private car parks, commercial premises,
hospitals, camp-sites etc.
Fig. 1 shows the constituent parts of the Vela unit,
including the pedestal casing, electro-hydraulic
operator and counter sprung beam assembly.
The electro-hydraulic unit is made up of two parts:
- The anodised aluminium lower casing contains the
electric motor and hydraulic pump. The pump delivery
rate varies according to beam length. The electric motor
is totally immersed in oil. The oil acts as a coolant and
transmission medium.
- The upper part houses a piston jack that is coupled to a
rack and pinion drive assembly. The central distribution
flange contains the locking and pressure adjusting
device. The two pressure valves allow precise
adjustment of the working forces that are transmitted to
the aluminium beam.
The Vela operator incorporates a hydraulic locking
system that will hold and lock the beam in any position it
has been stopped.
An emergency release device allows to override the
locking system by using the personalised release key.
The barrier pedestal is manufactured of mild steel that
has been sprayed with high gloss resin paint treatment
resistant to atmospheric corrosion. The extruded
aluminium beam is supplied in a white powder coated
finish and fitted with reflective strips. A rubber nosing is
fitted along the bottom edge to prevent damage in case
of accidental contact.
The Vela barrier can be supplied with rigid aluminium
beams or with a factory fitted skirt.
The Vela is suitable for left hand or right hand
installations and is supplied complete with fitting
accessories.
The counterbalance spring diameter is selected using
the table below.
