When a Booster amusement ride failed operation during high-season SPIT electrical mechanics attended the attraction to investigate the fault. An obsolete DC Drive was faulty and had to be replaced. The decision was taken to translocate the amusement ride to the nearest SPIT site in Almelo.

SPITs engineers started a reverse-engineering project to determine all relevant parameters for a retrofit by a new – modern – DC Drive System. Given the the challenging speed, control and safety features needed for the Pendulum ride our engineer decided to use the all digital ABB DCS800 series of drives.

Our partner ABB Ladenburg produced overnight a 450 Amps 4-Quadrant drive. Next morning the drive was picked up in Germany and transported by courier to the Netherlands. Meanwhile engineers from SPIT prepared the cabined and wiring for adapting to the new drive. The preliminary software was written in parallel.

After completion of the electrical installation the Booster was commissioned with great caution. After several hours of testing all safety and acceleration parameters were tested successfully and the amusement ride was ready for operation just before their next appointment.

This is just another great example on the wide spread of applications where SPIT can add value. In this case; great reduction of loss… And for our engineers a free ride after completion!

Pendulum rides are amusement rides based on the motion of a fixed pendulum. The configuration of the ride consists of a gondola, arm, and an axle. One end of the arms is fitted with a passenger-carrying gondola, while the other is attached to the axle. On some models, the arm extends beyond the axle and is fitted with a heavy counterweight. The counterweight is often used when the gondola swings through an inversion.

In addition to swinging back and forth, some designs incorporate rotating gondolas and may send riders through a complete inversion. Pendulum rides are propelled by one of two methods: a series of DC motors driving the axle, or wheels at the base of the station pushing the gondola as it swings by.
