General information
The stationary dock leveller with swing lip (PS2) is a new product of PROMStahl’s wide product
range. This top-quality product benefits from over 25 years of experience in designing and
manufacturing docking systems. The electro-hydraulic PS2 leveller is operated at the touch of a
button. As soon as the platform has reached its highest position the lip swings out automatically
and comes to rest on the lorry bed. During loading and unloading the PROMStahl dock leveller
follows the movements of the vehicle (automatic floating position). The PS2 dock leveller is
supplied including frame and installed in the pit as a compact unit in just one step. Additional
supports are not necessary. Considerable savings in installation and its tail-lift recess, i.e. the
possibility to accommodate tail lifts, are the big advantages of this system. The load capacity of the
PS2 dock leveller corresponds to the axle load limit taking into consideration the most
unfavourable loading case. The PROMStahl dock leveller meets the requirements of the most
recent European standards (EN 1398).

Swing lip
Standard swing lip
For ergonomic reasons the front part of the hinge lip is bent
by 5° and provided with a 100mm chamfered section. Thanks
to this feature, transition from the swing lip to the vehicle bed
is even more comfortable.
Page 5/20
We reserve the right to alter technical specifications.
Tapered lip
The most cost-effective way to reduce the contact area of the swing lip is to provide it with
tapered edges on both sides. This option offers 125 mm bevels on both sides.
Recommended for NW > 2,200 mm.
Fold-down segments
Our PS2 dock levellers are also available with fold-down segments. In this case the lip
consists of a central element and two side elements (located on the left and right hand side).
The side elements fold down independently of the central element. The lip width is reduced by
125 mm on each side so that vehicles with narrow beds can be also loaded and unloaded.
When the lip returns to its rest position, the side elements are automatically locked with the
central element so that the central element and the side elements are lifted together during the
subsequent swing-out process.
Recommended for NW > 2200 mm. This option is only available for lip length: 400 mm.

Swing lip „FALL GUARD“
The “FALL GUARD“ hinge lip feature guarantees optimum safety for the loading personnel.
When the dock leveller returns in its rest position, a 90mm section of the hinge lip is positioned
vertically above the platform surface, thus creating an obstacle and preventing the fork lift
truck and the warehouse personnel from falling from the ramp.
Platform
Tear-plate thickness
The platform is made of high-quality tear plate material (S235JRG2) and supplied with a thickness
of 6/8 mm or optionally with 8/10 mm. It is strengthened by means of special reinforcements
guaranteeing optimal stability as well as a sufficient transverse torsion strength of up to 10% of the
platform’s width.
Optimised connection between the platform and the lip guarantee safe operation and a long
lifespan.
Toe guards
Page 7/20
We reserve the right to alter technical specifications.
EPDM sealing
The EPDM sealing is used to seal the gap between the dock leveller and the pit so that draught in
the warehouse building is reduced, the staff’s working conditions are improved and energy can be
saved. The EPDM sealing is installed on the three sides of the leveller.
Platform insulation
Page 8/20
We reserve the right to alter technical specifications.
Surface treatment
Painting
Before final assembly, the individual components of the dock leveller are sandblasted and provided
with a two-component paint. Standard RAL colours are RAL 5010, RAL 7016 and RAL 9005 in a
layer thickness of 80 µm (corrosion protection class C2-M). Further RAL colours and layer
thicknesses of up to 160 µm (corrosion protection class C3-H) are available as an option.
To increase corrosion protection, the dock leveller can also be delivered with hot-dip galvanized
steel parts.
Hydraulic unit
The dock leveller is operated by means of a tried and tested hydraulic unit immersed in oil (0.75
kW). The closed system stands outs for its high reliability even under very difficult operating
conditions. We offer special hydraulic oils for use with low-temperature applications.
The dock leveller is lifted by means of two cylinders (Ø 40 mm) to ensure safe positioning even if
the lorry leaves the dock during loading or unloading. In this case the down movement of the
leveller has to be stopped; this is guaranteed by means of special emergency valves in the lift
cylinders.
The lip is swung out by means of a lip cylinder with a piston rod of 30 mm in diameter.

Frames / pits
Page 10/20
We reserve the right to alter technical specifications.
W frame (in combination with a pre-frame)
The frame can be mounted to the floor slab already before installation of the dock leveller itself.
The leveller is then welded to the pre-installed frame. Pit preparations are identical for T and W
type frames so that maximum flexibility is guaranteed.
Page 11/20
We reserve the right to alter technical specifications.
F frame (flat steel frame for leveller replacement)
This type of frame is used for easy and fast replacement of existing dock levellers.
With the F-type frame the existing leveller is cut out of the pit and replaced by a new one. The
existing frame is used again if it is not damaged and if its load capacity is sufficient. Thus, concrete
work is not required.
Page 12/20
We reserve the right to alter technical specifications.
P frame (mounted in the pit)
The dock leveller frame is welded to an angle at the rear side of the pit. The advantage of this
solution is the fast and easy installation of the dock leveler. This type of installation is suited only
for pits without tail-lift recess.

We reserve the right to alter technical specifications.
B (box)
No need to prepare a standard installation pit. Preparation of the building floor slab is much easier
as boarding work is not necessary.

Accessories
Buffers
Fixed buffers as well as movable buffers are designed to absorb impact during the docking process
protecting both the vehicle and the docking system. All rubber elements of our PROMStahl buffer
series are made of high-quality rubber ensuring a long service life.
Fixed-position buffers
PGF 70
Rubber element (thickness 70 mm) with plate (hot-dip galvanized)
PGF 90 and PGF 140 are designed for extremely high impact forces
Page 16/20
We reserve the right to alter technical specifications.
Height-adjustable buffers
These buffers are used for loading and unloading of vehicles whose lorry beds are higher than
dock level. Height-adjustable buffers can be lifted by up to 250 mm above dock edge. During
loading and unloading the buffer adjusts to the lorry’s vertical movements. It moves up to 50 mm
upwards and 250 mm downwards. Thus, the buffer’s wear is reduced to minimum and its
durability is extended. After docking the buffer can be fixed at dock level so that the lorry tailgates
can be opened.
Floating buffers
These buffers have the highest possible durability. They follow the lorry’s vertical movements by
150 mm upwards and 150 mm downwards so that the buffers’ wear is almost reduced to zero.
Page 17/20
We reserve the right to alter technical specifications.
Buffers with protective housing
For higher impact loads buffers with protective housing are recommended. The sloped protective
plate prevents the buffers from being heavily damaged.
Thanks to the lateral flat steel guides the fixing bolts of rubber buffers are optimally protected
against shearing.
Spring-steel buffer
Spring-steel buffers provide optimum protection for heavy-duty loading and unloading. These
buffers stand out for their excellent shock-absorbing characteristics, maximum resistance to
wear and long service life.
During loading/unloading only the buffer steel plate gets into contact with the vehicle. Thus,
normal tear of the surface caused by the vehicle’s height movements is excluded. Costly buffer
replacement is avoided and operating costs are reduced.
The spring-steel buffer is either welded to the frame or dowelled to the leveller.
Optionally, it is possible to mount the buffer 200 mm above the dock edge by means of a
support.

Wheel chock
The PZK wheel chock equipped with a position-dependent ultrasonic
sensor and connected to the control unit via a robust cable
guarantees safety during the whole loading and unloading process. As
soon as one of the rear wheels of the lorry is stopped by means of the
wheel chock, the leveller control function is “released” so that
operation of the dock leveller can be started.
