    Plastic Encapsulated Ladder System    
   

Ladder conforms to requirements of BSEN 13101-1 “Drain and sewer systems outside buildings. Part 3: Planning and come c/w a 200mm chamber wall clearance.

  
     
             
   

 

      
             
   
FP McCann manhole chambers come with plastic encapsulated steel double steps. These have health & safety advantages and make manhole construction easier by eliminating the need to line up left hand & right hand steps across chamber joints, as is the case with single staggered steps.
     
During the manufacture of our manhole chambers the latest technology allows us to punch plastic inserts into the inner chamber wall. Double steps can then be supplied loose to site, and inserted easily and securely on site without recourse to grouting. Supplying loose steps also avoids the loss of steps under benching. If the manhole requires a ladder then it is simply a matter of inserting a ladder double step, as opposed to the standard double step, and running ladder sidehold, available from FP McCann, through each side of the step to form an instant ladder. No need to measure up, order a ladder, return to site, drill and fit.
     
     
SUMMARY
  
A system that gives the user benefits of a durable plastic encapsulated ladder without the need to specify an exact length or fit on site. In addition a single specification can be used for all depths of access.
     
     
PRODUCT SPECIFICATIONS  

BS EN 13101-1 and BS1247 pt. 2
     
     
APPLICATIONS  

Concrete manholes and inspection chambers.
Renovation of existing structures.
     
     
MATERIALS  

High Impact Virgin Polypropylene copolymer plastic, yellow as high standard colour. If the ladder is to be subject to prolonged exposure to daylight then black or uv stabilised material should be specified. Structural steel reinforcement as standard.
     
     
PERFORMANCE  

Pull out load: 7.5kN minimum when fitted in accordance with
Manufacturers instructions.

Deflection under load: 5mm maximum at 2.5kN

Permanent Set: 0mm at 2.5kN

Impact: 20kg weight from 1 metre, no cracking.

Chemical Resistance: At least pH2 to 12

Integrity of plastic: 2M ohm at 500 volts DC

Thickness of plastic: 3mm minimum

Minimum cross section: 25mm diameter

     
     
ADVANTAGES  

Excellent Corrosion Resistance

Visibility

No Sharp Edges

 

Eliminates need to specify exact length or fit on site.

Steel reinforcement gives predictable deflection under load without causing brittle failure.

     
   
             
    Handhold...        
         
    The handhold entry pole system is suitable for aiding maintenance engineers in the initial entry into a manhole from the surface level. Once fitted, the entry pole is a permanent fitting in the manhole which is stored in the lowered position beneath the level of the cover. When required, the entry pole can be easily extended by simply hooking the easy to reach loop located at the top of the pole, pulling the handle upwards and twist locking into position. The handhold then provides a stable support to aid the entrance of the manhole as well as a clear visual indication of the location of the manhole when open. This helps prevent injury of other people in the area. Once the engineer has used the entry pole to aid their return to the surface, the pole is simply twisted to unlock it from the raised position and lowered back into the manhole ready for the next time it is needed.
   
             
    Specification        
    The handhold has a pole length of 1200mm and can be assembled to give three different distances from the pole to the wall. This is designed to accommodate different cover positions

   
         
    Advantages    
    • Helps the user find the first step safely.
• Creates visual aid to indicate location of manhole to other people in the area.
• Easy to fit.
• Easy to raise and lower.
• High strength for ultimate safety.
• Low cost
• Can be fitted to any Caswick step
• Two projections for round or flat walled manholes
