1. GENERAL DESCRIPTION 

Tall, magnificent towers have traditionally served as high-profile showpieces at amusement 

parks intending to attract and intrigue people from miles away. 

MAURER designed this Action Tower completely different from normal Free Fall Towers. 

Our Power Tower offers the following highlights: 

► Six different ride programs move the gondola 

We have created six different ride programs for different types of guests, families and 

teenagers etc. For example, one program features Jo Jo or Bungee effects. Another program 

provides a very fast way up, then, the gondola suddenly stops and drops by several meters at 

the same time (this can be compared with an airplane going through an air pocket), before the 

gondola goes up. Still another program creates an airtime effect, i.e. the gondola is lifted to the 

top extremely fast, does not stop up there, but drops again immediately, so that the rider lifts off 

from the seat and his shoulders are held down by the shoulder restraints for several seconds. 

►The Gondola can stop at each height level (useful for exit and entrance as well). 

All this is possible due to the drive technology of the gondola. 4 cable winches are driven by 2 

fast-moving special engines. The cables coil and uncoil very quickly and are connected to the 

gondola. 

► Tower gondola 

The gondola is very large. Every movement of the gondola carried out on the Power Tower can 

be seen from a great distance. At night, the illuminated gondola is a great attraction. So, it 

represents quite an eye catcher, and is very helpful to the marketing activities. 

The gondola can transport 32 people at the same time. So, the capacity (varying according to 

the riding program) is up to 1,350 pph.

► Outriggers / Foundation 

The Tower is supported by four outriggers, which have the advantages that the costs for the 

foundations are very low. A normal ground requires a concrete slab covering the total surface, 

which a thickness of approx. 20 cm. The customer does not need expensive foundations. 

► Riders 

Our aim is to attract as many visitors as possible, who really want to ride the Tower. 

To achieve that goal, we have the following strategy in mind: 

The Power Tower should not look too imposing to the crowd standing around it, as many guests 

might be frightened of the Tower. This strategy helps people decide to go for it, enjoying an 

eventful and attractive ride, which they previously might not have expected. Firstly, such an 

experience makes them proud of themselves and secondly, they had great fun. 

If the drop speed of the Tower is too aggressive, we know from our experience that with this 

kind of Tower, more people stand in front of it, just watching it instead of riding. 

Our customers have made an opinion poll and the result is: 

In a typical family park 40% of visitors ride the MAURER Tower. This is a very high percentage 

for this group of visitors and regarding the fact that it is a vertical ride. 90% of guests riding the 

Tower are certain to enjoy this attraction again, when they come back to the park. 

► Operational availability 

Very important is the available operating time of the Tower. The machine time at our customers’ 

site is 97 – 100% for a 56m Tower. 

► Security system 

Not only does our Power Tower have the highest hourly capacity, but, it is equipped with one of 

the best safety systems on the market, and is manufactured in accordance to the stringent 

German DIN and European EN safety standards (DIN 4112 / EN 13814) and it is certified by the 

German safety authority TÜV Sueddeutschland. 

Starting from the development of the Tower, TÜV Sueddeutschland was involved. All processed 

within the Tower are secured by redundancy. The control system consists of two independent 

PLC systems that are monitored.
