Platform shoe 2420, 2425, 2426
General
General
The platform shoe is used as a support for a working platform made up of timber
joists and scaffold boards. Primary joists are supported in the shoes and a platform
of scaffold boards or other timber decking is placed across them.
The working platform is quick and easy to assemble, and provides useful access
for painting and concrete finishing in confined areas such as lift shafts. It is also
useful for decking over service voids or other large floor openings.
The platform reduces the risk of falling whilst working within the lift shaft.
Positioning the pin support high on the bracket minimises the risk of rotation
under load.
The platform shoe is available in three sizes, to suit different joist dimensions. The
selection of the joist depends on the span, the loading, and other conditions
relevant to the application.

Safety instructions
Platform shoe 2420, 2425, 2426
Safety instructions
Always check products and equipment before use
Check the platform shoe before it is installed.
Never use damaged or rusty material that could impact on safety.
Do not combine products
It is not recommended to install, combine or interconnect platform shoes using
products other than those supplied by COMBISAFE. Combisafe product liability
only applies to combinations with correctly fitted COMBISAFE products.
Always use personal fall arrest equipment
1974_600
Personal fall arrest equipment must always be worn during assembly and
dismantling when a risk of falling exists. This also applies to work carried out from
a MEWP (mobile elevating working platform).
Figure 1. Personal fall arrest equipment.
Inspection after a fall
If a guard rail is subject to an accident or exposed to a heavy load, the rail must
be checked by a competent person. Contact Combisafe in the event of
uncertainty.

Safety instructions
Remember
• Plan the fall guard at an early stage; this will benefit everyone.
• Only use inspected safety products.
• Ensure sound and safe access to the installation site/work site.
• Cordon off below and around the assembly area in connection with the
installation so that unauthorized personnel are not injured if, for example,
you should drop tools or material.
• Use tools designed for the type of work to be carried out.
• Tighten screws properly and check that split pins lock correctly.
• Keep threads clean and lubricated.
• Keep the installation area in order.
• A safe workplace is an agreeable workplace.
• Many fall accidents occur from a low height.

The platform shoe angles are used to cover openings in slabs. The angle is fitted
on the platform shoe and then the entire unit is fitted to the edge of the slab. The
platform shoe angles are hot-dip galvanized.

Design and function
Design and function
The platform shoe is designed for the following maximum loads:
Material
Lightweight
concrete
Concrete
Maximum
permitted load
200 kg/shoe
850 kg/shoe
Comments
An increased load can be permitted if a
support plate is fitted to the lightweight
concrete under the shoe pin.
Contact Combisafe for confirmation.
Maximum load must not be imposed until
the concrete has achieved design strength.

Installation
Delivery
The platform shoe is delivered without accessories, casting sleeves, or anchors,
which must be ordered separately.
Preparations
• Read through the installation instructions before beginning installation.
• Refer to any instructions from the lift installer.
• Pay attention to any details such as cables, guides, etc.
• Check the timber quality before installation.
• Make sure that there are good access routes to the work area.
Installation
It is important that securing holes are level so that the work platform is flat and
steady.
NOTE
The distance between the centre of the cast-in sleeve/securing hole and
working surface depends on the size of the primary joist and the thickness
of the boards.
2420_012
The spacing c/c distance between the platform shoes is dependant on the
load and the board thickness.
Figure 12. Shoes level.

Installation
1. Install the platform shoes using one of the five methods below.
1: Casting in (Fig. 7)
Nail cast-in sleeves 2430 securely to the formwork. Secure the sleeve to the
reinforcement if necessary. After casting is complete and the formwork has
been removed, the platform shoe is installed by inserting the shoe pin into
the cast-in sleeve hole.
2: Securing with the shoe pin in a drilled hole (Fig. 8)
Drill a 20 mm dia, straight and level hole at least 85 mm deep. Remember
to blow out the hole after drilling so the shoe can be securely placed against
the wall. Install the platform shoe by inserting the shoe pin in the drilled hole.
3: Securing with an expanding anchor (Fig. 9)
Drill a hole for the anchor in accordance with the manufacturer's
instructions. Check that the platform shoe fits closely to the wall after
installation.
4: Securing with platform shoe angles (Fig. 10)
Fit the platform shoe to the platform shoe angle 2435/2436 to form a single
unit using the M16x20 set screw supplied with the platform shoe angle.
To ensure that the floor surface is level, decide whether you are going to
install the platform shoe in the upper or lower hole of the platform shoe
angle, depending on the dimensions of the primary joist. (See fig. 5 or fig. 6).
Drill the hole for the surface anchor in accordance with the manufacturer's
instructions. Fix the unit securely in place.
5: Creation of floor surface with tubing, couplings and scaffolding planks
(Fig. 11)
Install the platform shoe as described in option 2. It may be helpful to fit the
coupler on the platform shoe before installing the decking or boards.

2. Once the platform shoes have been installed and it has been ascertained that
they fit against the wall, measure the internal distance between two shoes.
Figure 13. Dimensions for cutting primary joists.
3. Cut the primary joist to length. Note that the joist must have a minimum
bearing in the platform shoe (see diagram).

MAX 10mm

4. Position primary joists in the shoes. It is important that the platform shoe is
mounted tight to the wall. Therefore, place a wedge between the primary
joist and the platform shoe to eliminate all free play. For higher joists above
145mm it can sometimes can be difficult to reach down to the platform shoe
with the wedge. Then chamfer (not shorten) the edge of the primary joist
according to lower pictures in figure 15. Finally, tighten the primary joist o
the platform shoe with screws to ensure a tight fit sideways as well.
Figure 15. Secure primary joist, using screws and wedges.

Installation

5. Install scaffolding planks to form a floor. The side openings to the wall edge
must be as small as possible, and must not exceed 200 mm, according to the
recommendations of the Swedish Work Environment Authority.
Minimise the cantilever of the boards beyond the joist to prevent tipping.
They should not cantilever more than 250 mm
Nail the boards to the joists, and ensure that they are flat and do not pose a
trip hazard.

Dismantling
Dismantling
The installation procedure should be performed in the reverse order when
dismantling.
Maintenance
Clean the platform shoes after use to ensure they are fit for use next time.
Safety checks
Safety checks are to be performed before use and after dismantling and before
parts are placed in the store.
Safety checks are to be carried out by competent personnel. Combisafe
recommends that only competent personnel trained by us carry out the safety
checks.
Check the condition of the platform shoe with regard to corrosion, welded joints,
cracks and deformations.
Inspection of the installed platform shoe
Check that:
• the shoe fits against the wall
• primary joists are properly secured to the shoe with nails
• boards and decking are properly secured to primary joists with nails
• the concrete has cured sufficiently to have achieved full strength
• all bolts are properly tightened
• there are no gaps bigger than 200 mm
• cantilever of the boards does not exceed 250 mm
• CC distance between the platform shoes and joist dimensions are correct for
the required loading
• boards have no cracks or knots.

Identification
The platform shoe is marked in two places (see figure 18) with a five character
identification number. This number can be of use during correspondence with
Combisafe.
