Partial Removal of a 33-Floor Goods Lift
We were instructed by one of our clients to carry out the large task of partially removing a 33-floor goods lift and the Lift machine replacement in a busy hotel in London. This site was a particularly challenging one to work on as Hilton Park Lane is one of London’s busiest hotels.
Hilton Park lane
Our Task:
Supplying and fitting 33 lift shaft hoardings
Lift shaft painting
Enabling works - cutting concrete trapdoors to allow the new machines to be installed and old machines to be removed
Enabling works - cutting concrete nosings to allow new lift entrances to be installed
Partial Lift removal - removal of all equipment, retaining the car and counterweight guide rails and counterweight frame
Site clearances - with no storage on site there had to be a continuous site clearance procedure of all redundant materials whilst the job was being carried out
Installation of the new lift machine and bedplate
Supply all lifting equipment required for all tasks
The Job:
The first port of call was to install the 33 landing hoardings to make the work area safe and secure. Using the running lift the shaft was then painted, helping to seal it from dust and improve visibility for engineers, as well as making it easier to maintain.
Our engineers then used the running lift to remove all door and landing equipment, dismantling all entrances and clearing the steelwork from the site each time the lift car had reached its weight capacity; the process was then repeated for all backfill behind the architraves.
The compensation ropes and pulley were then removed ready for the car to be tackled and de-roped.
Once the counterweight was positioned on props, the car was tackled and de-roped, removing over 1200 metres of rope from the lift and disposing of it in the correct manner- being licensed waste carriers, our company are environmentally aware.
All redundant and waste metal was removed from the site and recycled, and all concrete was taken to the correct waste disposal site.
Our team then began on the works in the motor room, dismantling the large Otis gearless unit and bedplate which was then to be lowered down through two pre-cut trapdoors getting us down through the double plant room into the lift lobby.
The machine and bedplate were taken down in manageable pieces and removed from the site using the correct material handling equipment.
We then removed the large redundant diverter wheel from the wheel housing space between the lift motor room and lift shaft and removed this from the site.
The new TK elevator SC400 gearless machine unit and bedplate was then delivered to the site.
Using a mobile Gantry, we positioned the unit on a pallet truck and moved it round to the lift lobby where it was transported to the top floor. The large bedplate and diverter steelwork were then tackled up through both trapdoors and assembled.
Our team then tackled the new machine into position and fixed it in the correct position to pick up the car and counterweight centres.
Once the new machine had been roped, we then had a cantilever scaffold installed at the top floor which we used to walk out on and hang the counterweight in the top of the shaft. This allowed us to clamp the ropes and remove the redundant lift car and sling, and all redundant pit equipment.
