Case Studies

In 2018 Alstom Trains was awarded the European Railway Traffic Management System (ERTMS) National Implementation Onboard Project in Norway. This project, to be delivered over a six-year period, involves equipping nearly 400 rolling stock vehicles with Alstom’s ERTMS system. Part of the installation work requires engineers to work at height on the train roofs and as Alstom has a strict rule that any working above 50cm is ‘work at height’, it is extremely important to ensure a safe working environment is provided for the engineers at all times. Consequently, Alstom issued a tender for a flexible and movable roof access solution together with a variable side access solution to accommodate the different types and shapes of rolling stock and provide the safe working environment they required.

What do you do when a supplier can no longer provide an after-sales service for critical safety equipment? This was a problem for a US helicopter engineering facility that had previously purchased access platforms from a French supplier, recommended by their Italian parent company. Unexpectedly, the supplier was unable to provide regular after-sales support in the US and as this was likely to be troublesome for the helicopter engineering facility, they decided to find a more suitable and reliable ‘local’ supplier. Their requirements had evolved too as they needed an engineering company with expertise in designing and manufacturing helicopter support equipment that could not only supply a quality product but also be capable of managing design change requirements, as well as providing 24/7 after-sales support. They also wanted to purchase equipment that could be easily repaired without the entire product having to be scrapped. To find a suitable supplier, the company issued a tender and after due process, Semmco Inc was appointed.

Variable height refuelling steps can be staged at different heights to accomodate dual fuellng connections quickly and safely.

Portable therapy oxygen cylinders, used in the aircraft for passenger assistance during flights, need to be serviced and charged regularly. This operation is made easier with the Semmco Oxygen Charging Rig without adding pressure to turnaround times.

When working in a time-critical environment it is vital that aircraft maintenance repairs are carried out safely and efficiently. The Walk Round Nitrogen Charging Kit is designed to provide an easy to use and convenient solution for topping up door assist bottles – critical to aircraft departures.

In order to carry out maintenance, engineers must gain access to a variety of equipment such as: passenger displays, telecommunications equipment, air-conditioning units and pantographs. For short periods of time it will also be necessary to maintain locomotive carriage roofs and it is important to minimise the length of time that this equipment is out of service.

HEAD10 is an award winning respiratory protection apparatur used for escape. It is a lightweight, ergonomic, closed circuit, hooded apparatus, that provides the wearer with a safe, simple and effective means of escape from an irrespirable or oxygen deficient atmosphere.

The Semmco SMART trolley provides customers with a low cost solution for oxygen and nitrogen refilling. The trolley includes safety features to address the issue of manual handling of cylinders along with a collapsable design suitable for cost effective international shipping.

Changing a wheel and brake pack on an aircraft is a testing operation as it involves moving large and heavy wheel and brake pack units along with tooling to the aircraft. The Semmco Wheel & Brake Service Trailer makes this difficult operation much easier.

In order to carry out an entry into an aircraft fuel tank, engineers potentially expose themselves to a combination of hazards and threats that need to be adequately controlled before an entry is made.
