Here at Garmendale, we embrace the importance of safety, continuity and downtime. Your business is our business, and the comfort and safety of your visitors is vital to both of us. In fact, we have provided engineered shot gun gates to many of the fastest, highest and most exciting rides in Europe, and have built up a proven track record of ensuring effective, safe and comfortable visitor throughput.
Engineered to the highest standards
Our range of shotgun gates are designed and manufactured to meet BS 7036 parts 1, 3 & 4 Code of Practice for safety of powered doors, and BSEN ISO 13849 covering safety-related parts of control systems. The usual Garmendale Engineering high-quality procedures for design and manufacture also apply. The system has been designed so that at no time is high pressure used on the gate activating cylinder – this is one of the main safety aspects of the design. The soft start dump valve is activated by the ‘E’ stop system on the main ride and should the ‘E’ stop be pressed anywhere on the system at any time, it would immediately dump the air from the gate system. If the gates are in part open or part closed mode and the gates are pushed manually, they will go into gate closed or gate open position
Maximum safety and comfort
Our shotgun gates are available with two key operating systems. The first of these is the pneumatic gating system and there is also the recently added electrically operated gating system. Both provide maximum visitor comfort and safety, by preventing closure, if the mechanism senses that there is an obstruction i.e. an arm or leg. Unlike conventional kinetic energy locks which can be forced open, our system mechanically locks, preventing unauthorised entry and maximising safety. If they were pushed closed, they would mechanically lock once the gates have reached the fully closed position. In addition, our pneumatic control panel is also built in-house ensuring that the gates can be fully integrated with the ride’s control system should you wish. This prevents despatch unless all doors are closed and locked properly. We can also send signals direct to your own ride control system. What’s more, all of our gates are fitted with coded switches. This makes it impossible to activate the gates or ride any other way than that intended by the detailed design risk assessment, therefore ensuring visitor safety and avoiding costly mistakes.
All of our gates are designed to the highest BSEN 1090 standard to ensure long-lasting safety, reliability and durability. We have installed systems that are regularly used and have been in place since 1994. To understand how complex your system needs to be we would start our process with a detailed design risk assessment, taking into consideration operational requirements and maximum safety. Our gates are shot-blast zinc rich primed and powder coated to BS or RAL colour codes, and are available in a stainless steel polish or satin finish. Alternatively, we can work with your creative team to come up with a variety of themed effects. Not all environments are suitable for gates, so our engineering versatility has enabled our mechanism to be used also on solid doors.
A brief history
At Garmendale, we have been making shotgun ride gating systems for many years. The simple, clean design has ensured years of trouble free operation for parks around the world. Here’s a few examples.
Nemesis operating since March 1994
Fully interlocked into the ride safety system of this Bolliger & Mabillard coaster, giving a capacity of two trains each consisting of eight cars, at four across giving access to 64 riders at any one time. Top speed of 50mph.
Oblivion operating since March 1998
Two barrier gate systems, switched when the main transfer table is operational. A Bolliger & Mabillard drive coaster reaching 68.4mph with a ride duration of 1 minute 15 seconds.
Thorpe Park, Colossus March 2002
Incorporated into Intermin’s ride systems, Colossus is the UK’s only quadruple inversion coaster or corkscrew. Showing a standard system and styled with perforated mesh in-fill panels it’s finished in theme colours. It loads two trains, seven cars at two across, fulfilling a ride capacity of 1200 per hour, at a maximum speed of 48mph and reloading every 1 minute 45 seconds.
Air Ride March 2002
Our system is incorporated into the first flying roller coaster designed by Bolliger & Mabillard ride systems – Air Ride at Alton Towers. Showing a bespoke configuration of the RG11 system trough mounted, and using 316 brushed stainless steel to achieve the client’s required finish. It has a dual platform loading station, allowing three trains to operate simultaneously. Capacity is 1500 riders per hour at a top speed of 47mph.
Nemesis Inferno April 2003
Manufactured by Bolliger & Mabillard, this is an inverted coaster ride lasting approximately two minutes at a top speed of 50 mph and reaching a capacity of 1000 riders every hour. It consists of two cars with seven riders at four across, giving 28 riders per train.
The Smiler Gerstlaur infinity coaster May 2013
Five trains with a typical electrical and pneumatic control enclosure.
S.W.A.T. Ride March 2005
Incorporated into the S.W.A.T. ride at Thorpe Park designed by S&S ride systems. It has a standard system, styled with perforated mesh in-fill panels and finished in theme colours.
Sonic spin ball March 2004
Opened in 2004 and still in full operation.
Rita Queen of Speed April 2005
Rita is an Intamin accelerator coaster that reaches 61mph.
Charlie and the chocolate factory April 2006
From Mack Rides and handling 1000 riders every hour, at ten boats with nine people per boat and giving an 11 minute ride.
Intermin freefall drop coaster
Reaching 41mph and handling 1400 per hour.
Swarm March 2012
Our system is incorporated into this Bolliger & Mabillard ride. Swarm offers an extreme near miss experience in a church themed disaster zone with hard wood queuing pens imitating church pews and steel gates. It has a capacity of 1300 riders an hour at a top speed of 59mph.
Nemesis sub-terra March 2012
Fully integrated into the ride safety system of this ABC’s Freefall tower ride system, it has an RG11 system fitted to the client’s bespoke design. We manufactured two themed one hour fire rated doors complete with pressure sensitive switches and intumescing closures. This unique system went to the next level of safety requirements and created the next generation. It meets Performance Level E and (Safety Integrity Level 3?) and with a six metre drop at 21mph it creates a whole new dimension.
The Coca Cola London Eye
Incorporated into the London Eye and positioned at the main entry platform. It shows a standard system, using 316 brushed stainless steel to achieve the required client finish, due to its proximity to the River Thames.
Stealth March 2006
An Intermin accelerator coaster reaching 80mph and giving a 19 seconds ride.
Maurer Sohne Spinning Coaster
850 riders per hour and travelling at 38mph.
Orlando Eye March 2015
The 400-foot tall observation wheel provides breathtaking views of Central Florida in all directions, with sights of downtown Orlando’s skyline and theme parks.
Control cabinet, designed, built and installed in-house at Garmendale.
RG11 gating system
Operator controlled by push button. The operator has complete vision of the ride platform entry and exit and operates control from that point only. Read more here.
RG12 gating system
Entry is triggered by the ride which enables the fast throughput very often needed on roller coasters. It also adds to safety control with ride integration forming part of the safety circuit.
RG14 gating system
A more complex specialist system which usually includes many elements of entry and exit – multi-door control. No matter how large or small, all of our systems are based on low 3 to 4 bar pressure, thereby providing an anti-crush mechanism.
