A very efficient and effective operation, envisaged by the plant engineer, designed and built by Supreme Hoists, within budget, making innovative use of vehicle hoist component. When everything is ready to hand, the platform is lowered to a convenient height above the truck, hatches are slid open, filling is carried out by the driver approx 15min turn-around.
Supreme Hoists and Atrium Lift Co have been involved in the manufacturing and upgrades of such stage lifts from the early 90's.
We have successfully designed, manufactured and commissioned stage lifts in:
1993 Wellington State Theatre
1998 Napier Masonic Theatre
2000 Albany/Massey University
2001 Rotorua Church
2005 – 2006 St James Theatre Wellington
Michael Fowlers - (Earth Quake restraint Upgrade)
2012 Reconfigure A.S.B Theatre Auckland
With over 40 years of experience in manufacturing lifting equipment we have taken and used our knowledge in mechanical and hydraulic lifting systems to achieve the customer's desired result.
Our greatest engineering achievement would be Saint James TheatRE, two independently movable 3.6m mechanical lifts with hydraulic prop ups.
With a combined area of 32 square metres these two stages are capable of supporting a combined loading of 24 tonne in a force 9 earth quake with a safety factor of 3:1.
These two stages are capable of being stationed at any height with in the range of movement available giving the theatre greater versatility in stage performances.
Lifting speed approx 33mm per second i.e 2m per minute.
Lately there has been a demand for high lifting speeds 6m per minute i.e 100mm per second
mechanically this requires a lot of power
hydraulics can halve this
our goods lifts employ a very controllable electrical technique for hydraulically lowering heavy loads
Theatrical stage lift – curved trusses.
We think this can be utilized in parallel on a stage lift or similar situation to keep a number of independent hydraulic rams, pump and motors reasonable synchronization.
