Description |
The Pentalift MD Series Mechanical Dock Levelers
are designed and built to provide superior
product value through prolonged, trouble-free
performance. Its semi-automatic operation
requires no manual lifting. Pentalift MD Series
Mechanical Dock Levelers are operated by a
simple pull chain release at the rear of the
deck. All Pentalift dock levelers are
factory-tested before shipping.
When the operator pulls the release ring located
at the rear of the deck, the deck rises to its
full height. During the upward deck motion, the
lip automatically extends into position. The
operator then "walks" the deck down until the
extended lip rests on the truck/trailer bed. The
deck floats over the entire operating range to
accommodate the movement of the truck/trailer
suspension. All Pentalift MD Series Mechanical
Dock Levelers use the patented Easy-Float
hold-down assembly. After truck/trailer
departure, the lip automatically retracts behind
the dock bumpers. |

Structural Features |
 |
High-strength safety checker plate
deck and lip assembly, 55,000 psi yield. |
|
|
Full-width, self-cleaning, heavy-wall
hinge tube, 70,000 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, precision-formed “C" beams,
65,000 psi yield. Specially designed
beams allow Pentalift to create and
build the deck support with optimal
strength-to-weight ratio for a dock
leveler. Utilizing eight (8) 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 |
|
|
Positive lip lock assembly maintains extension of
the lip, then automatically retracts
once the truck departs. Lip is yieldable
if contacted in extended position during
truck/trailer positioning. |
|
|
Lip-assist spring assembly
counterbalances the weight of lip for
smoother extension and retraction. |
|
|
Computer optimized cam profile reduces “walkdown” forces. |
|
|
Mechanical safety legs, with below level
center, limit platform
freefall in the event of premature truck/trailer
departure. |
|
|
Full-range telescopic toe protection
assures total dock attendant safety.
Section features a “bend
relief” to increase strength. |
|
|
Fixed rear hinge remains flush with rear
of the pit to eliminate potential pinch
points and surface obstruction. Design
allows 4” of lateral deck compensation
to accommodate canted truck/trailer
beds. |
|
|
Heavy-duty, adjustable lift springs. |
|
|
Safe, easy maintenance with only three
adjustment points, conveniently located
at the front of the leveler, eliminate
the need to enter the pit. |
|
|
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.
Easy
Float Hold-down Assembly (click for details)
The Easy-Float hold-down assembly ensures
stress-free operation. The Easy-Float hold-down
assembly can be
released in any position with a minimal release
force of 8 lb. Contact between the lip
and truck/trailer bed is guaranteed since the
Easy-Float hold-down automatically compensates
for the up and down movement of the
truck/trailer suspension. |

Dock Leveler(s) to be Pentalift model
MD__________________ manufactured by Pentalift
Equipment Corporation. Nominal deck size of
_____' wide x _____' long with a rated capacity
of _____lb. The nominal lip length will be 16".
Mechanical Dock Leveler(s) to be semi-automatic
with no manual lifting required. The
hold-down assembly is to be the Easy-Float
design requiring a minimal release force of only
8 lb. The Easy-Float hold-down assembly is
to maintain lip contact with the truck/trailer
bed by allowing the leveler to float with the
suspension of the truck/trailer. A high
strength, braided nylon strap is to be used to
connect the deck and frame assemblies and to
absorb shock loads. All adjustments are to
be conveniently located at the front of the
Mechanical Dock Leveler(s). The lip is to
retract if impacted during truck/trailer
positioning. The lip hinge is to be welded
to a high tensile headboard. The rear
hinge is to be a full width, fixed style.
The deck design shall provide 4" of lateral deck
compensation for canted truck/trailer beds.
Mechanical Dock Leveler(s) to be equipped with
operating range toe guards, night lock and a
maintenance stand. Two molded rubber
bumpers will be provided. Mechanical Dock
Leveler(s) to have Pentalift gray finish. |
