This is a case study for a recently engineered solution. In this scenario, understanding problems with status quo led to a evolutionary new design and raising the bar for safety standards in container repair yards
Defining the problems
I’ve had the opportunity to visit other container parks and witness the methods traditionally adopted. The basic A-frame trestle container stand is commonly used to raise containers for inspection and repair. Constructed from box steel they are pretty sturdy, however, with an absence of working load limit certification, it is difficult to know their rating.
A knock from mobile equipment could easily change the weight distribution and exceed the operating capacity and buckle or over the stand.
Would you want to be underneath when an accident happens?
The 40′ container stands are constructed from a larger box steel. The problem with this arrangement is that you need two stands available for every container, in a combination of 20/40′ – (Problem 1).
The client had limited space for operating maintenance and repair (M&R). If using the separate container stands, they would need a large area available, and to constantly arranging them into position, which would be a waste of resource time – (Problem 2)
Another issue is that a 20′ stand bay needs to be completely reconfigured to accept 40′ containers. The width of mobile equipment are too wide to get between 20′ stand, due to their ‘A-frame’ design. It would put them at risk of damage too.
Container stands can only accommodate one container at a time. The client required a flexible solution that could accommodate both 20′ and 40′ container simultaneously – (Problem 3)
Problems / Challenges
To recap on the issues identified:
- Two stands for every container, a lot of equipment that is lightweight and prone to damage.
- Separate stands require constant reconfiguration for different container sizes.
- Separate stands only accommodate one container at a time.
Design a solution that would allow mobile operator to continuously work with multiple 20′ and 40′ containers without the need of reconfiguration.
The idea was to build larger stands which could to accommodate two x 20’/40′ containers simultaneously, whilst remaining mobile for flexible operations. The A-frame issues were negated by using a counterweight to prevent tipping, which allowed a gap for container handling equipment to drive between the stands.
With this solution the mobile equipment wheel tracks are between the stands span, so they do not need to be moved each time. The stands also weigh significantly more, so are less susceptible to movement from knocks and bumps during normal operational use.
This solution is fully engineered and certified. Meaning the M&R employees feel far more comfortable working underneath, and significantly reduced risk to business and injuries.
These stands are available globally engineered to your specification.
