Walk Around Charge Kit from Semmco reduces manual handling

Semmco has enhanced its Walk Around Nitrogen Charge Kit to provide a safer, more efficient way for engineers to service aircraft door systems and tyres. Designed for single-person operation, the portable kit reduces manual handling, simplifies maintenance tasks and helps support faster aircraft turnaround times.

Semmco, part of the HAKI Safety Group has released its enhanced Walk Around Nitrogen Charge Kit, a portable nitrogen charging kit designed to provide an easy-to-use method of topping up aircraft door systems and tyres without the traditional manual handling and safety concerns. It also improves efficiency and enables quicker turnaround times.


The Walk Around Charge Kit is easily managed by one person and simplifies maintenance tasks that traditionally requires two operators to complete, such as replenishing nitrogen on aircraft door systems. The kit is self-contained in a robust, rain shower proof carrying bag, with double zip to allow easy access.  The user has clear visibility to the gauge, that offers a reading of the cylinder pressure level and the output pressure being delivered for the application; with an ON/OFF valve supplying gas to the regulator.


The regulator and relief valve assembly are housed in a damage resistant close foam protective lining, incorporating a 1.5m charge/connection hose and Shrader connection on the hose end for easy connecting to door assist bottle.


A cylinder charging connection point is located on the side of the valve body using a designated charge adaptor to prevent cross contamination and inappropriate charging methods.  The Walk Around Kit can be configured for high- or low-pressure cylinders, depending on requirements.


The cylinder and bag weigh just 6.5kg, reducing strain for the operator and contributing to safer working practices.   All elements are tested to the correct standards and meet both US DoT, European and UK regulations.

“We designed the Walk Around Charging kit to provide a more efficient and safer way of completing a critical task during aircraft turnaround.  What was once a two-person job can now be carried out safely by one engineer taking the Walk Around Kit to where it is needed. We are leading the way in GSE design innovation, and this is a prime example of our ability to assess a task and design a solution that brings benefits to both the engineers on the ground and the airlines themselves.”
