2.5 Hydraulic Unit Installation
Refer to separate manual for information on the specific model provide.
2.5.1 Typically, the Model 400 series hydraulic unit is mounted on a concrete pad.
Generally, the hydraulic, electrical power, and control conduits will be run
together, and all will turn up out of the concrete pad to attach to the
hydraulic unit. Additional conduits may be required for traffic lights, loop
detectors, and other options. Contact B&B ARMR if you are unclear about
the conduit requirements for your installation.
2.5.2 Place the hydraulic unit on the pad over the exposed conduits and bolt the
unit in place. (The feet on the unit will accept standard concrete anchors.) If
you mount the unit to an intermediate steel structure, make sure that
structure is securely fastened to the pad.
2.5.3 Terminate the electrical power and control conduits in the electrical box and
the hydraulic hose conduit to the hydraulic side of the HPU. The hydraulic
conduit should be cut flush with the concrete pad. This will allow the
hydraulic hose to move slightly when pressure is applied without rubbing
against any sharp edges on the conduit.
2.5.4 Install the hose by pulling it into the conduit, making sure to protect the hose
from any sharp edges. When you cut the hose to length do not cut it too
short, as the hose will shrink in length when under pressure.
2.5.5 Connect the hoses to the fittings located on the manifold. The two fittings
on the left side of the manifold operate the gate, while the set on the right
operate the locking pin cylinder (model 450 & 450A only)
2.5.6 The hydraulic unit's oil tank holds 30 gallons. Approved hydraulic oil must
be added by removing the tank lid and pouring into the tank. The tank
should be filled until the oil is half way up the sight glass. (See the
Maintenance
section for oil specifications and additional details.) You may
see small amounts of oil in the unit when it arrives. This is residue from
factory testing prior to shipment
