Description |
Pentalift HU Series Ultima Hydraulic Dock Levelers
are designed to provide superior product value
through prolonged, trouble-free performance.
Convenient push button activation and proven
hydraulic technology increase the efficiency and
safety of the loading/unloading process. Pentalift
HU Series Ultima Hydraulic Dock Levelers provide superior performance
in high frequency loading/unloading, heavy load and
abusive environment applications. All Pentalift
dock levelers are factory tested before
shipping.
When the operator pushes and holds the raise
button, the deck rises to its full height. The
lip then extends into position. When the
button is released, the deck and lip lower until
the extended lip rests on the truck/trailer bed.
If there is no truck/trailer present or the truck/trailer
departs, the deck lowers, contacting the below
level stops. The lip automatically drifts into
the pendant position behind the dock bumpers. On
units equipped with automatic return-to-stored
position, the deck
returns to the stored position with the lip
behind the night lock. Deck lift and
lip extension are controlled through the Pentalogic
Hydraulic Manifold. |

Structural Features |
 |
High-strength safety checker plate
deck and lip assembly, 55,000 psi yield. |
|
|
Full-width, self-cleaning, heavy-wall
hinge tube, 65,000 psi yield. |
|
|
Gussets on lip and headboard hinge
maximize support. |
|
|
50,000 psi yield headboard with
bridged gaps and radii on all inside
corners for maximum strength |
 |
Structural “I" beams.
Structural "I" beams allow Pentalift to create and
build the deck support with optimal
strength-to-weight ratio for a dock
leveler. Utilizing six (6) beams
assures an even load distribution and
maximum deck support. |
|
|
Central deck beam for added support of
three-wheeled vehicles. |
|
|
Full-width, structural channel tailboard
and one-piece, full-width rear hinge
complete with heavy steel gussets.
Pentalift’s unique, welded assembly
provides a box section for superior
support. |
|
|
Rear frame assembly features eight
points of even support for the
full-width rear hinge. |
|
|
Heavy-duty front frame provides
full-width, cross-traffic support and
superior building aesthetics. |
|
|
Night lock prevents unauthorized entry
when overhead door is locked on top of
dock leveler. |
|
|
Operating Features |
|
|
Self-retracting, hydraulic lip cylinder
is standard on all models for fully
hydraulic operation. |
|
|
Top-fed, forward-positioned hydraulic
lift cylinder. |
|
|
Full-range, telescopic toe protection
assures total dock attendant safety.
Section features a “bend relief” to
maximize strength. |
|
|
Fixed rear hinge remains flush with the
rear of the pit to eliminate potential
pinch points and surface obstructions.
Design allows 4” of lateral deck
compensation to accommodate canted
truck/trailer beds. |
|
|
Hydraulic power unit incorporating
internal filtration system, 1 1/2 Hp TENV
motor. |
|
|
Maintenance stand supports deck
and lip during maintenance and
service. |

Balanced Design for Structural Harmony |
Other dock leveler manufacturers boast of
individual components as though they were
unrelated to each other in strength. Little
thought is given to the overall structural
balance of the combined load-bearing components. Many dock leveler manufacturers fail to realize
that, in many respects, the combination of
structural components is similar to a chain and
a chain is only as strong as its weakest link. Through the use of state-of-the-art finite
element analysis software, Pentalift components
are designed and sized to maintain structural
balance and harmony throughout, assuring maximum
dock leveler life by eliminating any weak links.

Combination Control Panel
(click for details) |
Combination Control Panels are available to suit
various applications and combinations of dock
equipment. Combination Control Panels are used to
simplify and harmonize the operation of the
loading dock equipment, increase safety, reduce
field-wiring costs and conserve wall space at
the loading dock. The dock equipment that is
typically interlocked is any combination of:
hydraulic dock leveler, vehicle restraint and
safety light system, overhead door and/or
inflatable dock shelter.

Pentalogic Hydraulic
Manifold (click for details) |
Operating every hydraulic function with only two
moving parts, the Pentalogic Hydraulic Manifold
revolutionized dock leveler hydraulic control
circuitry. Conventional hydraulic dock leveler
control valve circuitry is comprised of several
individual function valve assemblies. These
assemblies are constructed from many sub
components, increasing the potential of
hydraulic component failure and oil leaks.
Utilizing only two moving components, the
nonadjustable Pentalogic Hydraulic Manifold
eliminates all concerns related to on-site
adjustment, oil leaks or hydraulic component
failure.

|
Self Retracting Lip (click
for details) |
A major feature of the Pentalogic Hydraulic
Manifold is a self-retracting lip, an
important safety and performance feature.
With conventional hydraulic dock levelers, the yieldable
lip circuits utilize an “in line” pressure
relief valve, maintaining the lip in the
extended position. Once a truck/trailer departs, the
deck lowers and the lip remains in the extended
position. The next incoming truck/trailer will impact
the extended lip and any excessive force will
push the lip back into the pendant
position. In addition, a conventional hydraulic
circuit can cause the lip to get “caught on” a
portion of the incoming truck/trailer, resulting in
extensive damage to the truck/trailer, dock leveler
and cargo.
On truck/trailer departure, the Pentalogic Hydraulic
Manifold allows the lip assembly to gently
retract into the pendant position prior to the
arrival of the next incoming truck/trailer. The Pentalogic
Hydraulic Manifold assures that the
lip is always pendant behind the protective
bumpers. Units equipped with automatic
return-to-stored position work in conjunction
with the self-retracting lip (eliminating false
signals common with other makes) to return the
deck to the safe, stored position.
