Application of Two Types of Elevated Excavators
At present, there are two types of elevated excavators designed for special construction scenarios: straddle excavators (long-leg excavators) and high-bed excavators.
The straddle excavator features an ultra-high ground clearance and obstacle-crossing chassis. It is mainly used for special projects including railway construction, port operation, mining and wetland engineering overseas to overcome the limitations of standard excavators. In railway freight yards, the machine can straddle railway wagons directly. With an elevated cab offering a full view, it efficiently unloads bulk cargo such as coal, ore and sand without temporary scaffolding. Trains can be processed immediately upon arrival, greatly shortening transit time. Widely adopted in railway terminals across Africa and Southeast Asia, it also carries out railway maintenance work, including ballast cleaning and ditch excavation above tracks without interrupting rail traffic.
The high-bed excavator is equipped with a lifted chassis with excellent wading capacity, enabling trenching and excavation in shallow water areas. It is widely used in marsh and tidal flat renovation projects. As a cost-effective alternative to amphibious excavators, it effectively cuts down overall operation costs.
We are a professional manufacturer of straddle carrier and elevated chassis structures for excavators. Our straddle carrier could be customized on height and width to meet your different working condition in railway transportation. And, our elevated brackets can raise the machine height by 1 to 3 meters. Adopting tubular steel construction, our structures perfectly fit all mainstream excavator models. The refitted elevated excavators with our straddle carriers and elevation structures are widely used in material handling for railway wagons, cargo loading and unloading in port, river regulation, coastal development, wetland construction, shallow water operation, pipeline laying, land reclamation, waterway dredging and delta reclamation projects.
