Horisont Stairway Safety instructions Safety instructions Always check products and equipment before use. Check all included stairway parts before assembly. Never use damaged or rusty materials as this can affect safety. Do not combine products Stairways that are mounted, combined or connected using products other than HSS products are not recommended.
Safety instructions Horisont Stairway Remember • Plan walkway locations at an early stage, this will benefit everyone. • Use only safety-controlled products. • Cordon off below and around the assembly area in connection with the instal lation so that unauthorized personnel are not injured if, for example, you should drop tools or material.

Horisont Stairway Technical data HP1023 Universal support Weight: 18kg Used to support stairways of 18 and 21 steps, and to stiffen stairways of 15 steps when set up at a low angle. The telescopic support is adjustable to fit dif- ferent stairways and base surfaces.
Design and function Horisont Stairway Design and function All the steps are pivotally connected through the four supporting side piec- es. To prevent the steps from tipping forward when going up or down the stairs have a latch that locks the steps. The latch, which is attached to the upper side piece, snaps into the lower side piece with the help of the handle and thereby locks the stairs so that it cannot be collapsed.
Horisont Stairway Assembly Assembly Delivery The stairway is delivered in the collapsed state. Handrails are packed together with the stairway. The stairway is not normally assembled. Pic 22. Stairs on delivery Equipment for assembling and erecting a stairway The following personnel and equipment are required for assembling and erect- ing a stairway- •...
Assembly Horisont Stairway Assembling the handrail It is advisable to mount the handrail before erecting the stairway. Mount the handrail to the stairway by pushing the ends of the posts down into the sockets on the steps. Make sure the posts go all the way down. Mount the handrail with the curve on the upper rail at the top.

Assembly Horisont Stairway NOTE! If the steps lean backwards due to the supporting surface not being level, the stairway must be collapsed slightly. This is achieved using the handrail. The lock must be released at the same time. Now place blocks on the sup- porting surface under the rear side rails to make the stairway ’s contact...
Horisont Stairway Assembly Mounting Slab attachments Mount the scaffold attachments on both stairway sleeve joints. Make sure the locking bolt is unscrewed to permit hooking over a scaffold pole. Lift the stair- way and lean it on the scaffold tube on which it is to be fixed. Let the stairway slide down so that the hooks grip the scaffold pole.
Assembly Horisont Stairway 4. Adjust the length of the support leg to bear on the ground/sole plate . The top of the leg must be above the top of the the locking device sleeve . Tighten the handle firmly so that the support leg is secured in the friction surface in the locking device.

Horisont Stairway Assembly Mounting the beam For selection of beam sections and number of steps, refer to fig. 5, and “ Table for supports and beams” on page 9. 1. Select a surface that is as level as possible. 2. Lay the collapsed beam sections with the cross braces downwards.
Assembly Horisont Stairway Assembling stairways on beam -- NOTE! --- When joining stairways, it is only possible to have an extended top step on the upper stairway. Other top steps (HP10518) must be replaced with nor- mal steps (HP 10511).

Horisont Stairway Assembly 6. Push the stairways together, they must be opened the same extent, use the handrails if necessary. One person should stand beside the joint and check that all four points on the upper stairway slide into the lower stairways side rails.
Assembly Horisont Stairway Erection of stairways on a beam Erection is performed in the same way as described under heading “Erection of stairway ”, with the exception of the procedure described in point 1. In- stead, connect the crane sling just above the middle of the stairway, around the beam’s upper section inside the handrails.
Horisont Stairway Maintenance Maintenance To ensure the stairway ’s function and safety in the future, always handle it with care. If a stairway is damaged, it must be repaired before being used again. Safety checks Safety checks are to be made before use and after dismantling and before parts areplaced in the store.
Maintenance Horisont Stairway Scrapping Those parts identified during the safety checks and which have not been possible to recondition should be discarded and destroyed so that they can- not be used. Once the stairway has reached the end of it ’s life due to dam- age, rusting or wear, it can be handled as galvanized steel scrap.
