Maintenance Stand Design

Dynamic Engineering specializes in the design of high capacity maintenance stands

Dynamic Engineering specializes in high capacity maintenance stand design. These stands are designed using the principles of the Australian Standards (AS2538) and experience gained in this field over a period of 10 years. Stability and strength as well as ease of handling are taken into account during the design process. From a design point of view, we use Finite Element Analysis, which is applied to each design, making it possible to ensure that the stand has adequate capacity to resist deformation and buckling. All designs are engineer certified – meaning that a Chartered Engineer, Registered with Engineers Australia, has signed off on the design.

Below are some examples of our many designs:

Mobile Equipment Maintenance Stands

At Dynamic Engineering Consultants we are always adding to our design inventory and as such we have developed maintenance stands for several existing machines. For example, the stands shown below is for a Komatsu WA1200 front end loader. These stands have a 200T capacity (100T each side).

After finishing the design, shop drawings were produced and the stands were fabricated. Below are eample of these stands in three different sizes.

Stands With Wheels

To easily move equipment on stands, wheels are added, see the examples below:

Rotor Shaft Stands

When ultra fine grinding mill rotor shafts need to be maintained or replaced, custom made shaft stands are required which can withstand the weight of the shafts. Our client needed these stands urgently and Dynamic Engineering was able to design these stands so maintenance could run on schedule.

Client’s Custom Design Stands

Many of our clients are happy to fabricate their own equipment, but need help converting their concept ideas into a design that complies with the Australian Standards. Dynamic Engineering works with the client, fine tuning the maintenance stand design until complies, and can then assist with generating accurate fabrication drawings.

In one such an example, our client wanted to analyse a drill mast stand with a WLL = 25T. Below is the concept along with the final design.

Final Design

The concept had to undergo several modifications to comply with the stress, deflection, stability, buckling requirements. In addition the pins were checked to see if they were strong enough and finally the stand was checked while being lifted with the forklift.
