Standard Excavator is used for digging of trench, holes and foundations, and for some material handling etc. job, There are some jobs like river dredging, pond cleaning and canal maintenance that needs excavator have a lot of reach, For this situation, a long reach booms front can convert standard excavator into a long reach excavator that working range around 50% at height and forward, we have many customers whose excavator has two kits of boom arm configuration, one is their original standard boom arm, another is long reach booms kit for special some projects that need excavator reach longer.
If you already bought excavator long reach booms from your attachment supplier, do you know how to inspect the quality? We listed some tips for your reference to check boom arm quality, it is also useful when you at an exhibition, and I think it can be applied to all steel structure products.
1 Reasonable structure, excavator boom arm is designed under mechanical stress analysis, on boom arm , there are some areas withstand strong force need to be reinforced, for example, area that close to hinge, cylinder bracket. In where thicker steel and gusset are usually used as a way of reinforcement.
2, Steel property, That every material has been chosen and proved is right has its reason. With the development of IT technology, FAE software(finite element method) can simulate material stress situation under specific force. That also has been applied for boom arm design. The result indicates Q345B steel yield strength of which reaches 345Mpa is capable as boom arm material, only for huge machine or more tough job, that requires higher strength of steel.
3, welding quality, good welding line is even, 1-2cm high,
4,Painting, good painting is a guarantee of long lifetime, that prevent product from rusting in some special environment like sea water, it is also necessary to repaint if boom arm was scratched
