Hydraulic Cylinders for Civil Engineering

Hydraulic Cylinders for Civil Engineering Projects

Water Level Control and Flood Protection

Hunger cylinders are used in modern dams for the positioning and control of level and flood protection gates. Cylinders for radial gates, rotary gates, slide gates and flap gates are bespoke engineered to meet the requirements of the project specifications, according to DIN and ASME standards but also regional standards where necessary and any special customer requirements. Load holding, synchronization and safety functions are incorporated into hydraulic manifold blocks directly mounted onto the hydraulic cylinders. Hunger also engineer and supply these manifold blocks together with associated power packs, thereby providing complete customer system solutions for civil engineering projects. A reference list representing decades of experience from more than 100 projects is available on request.

Ship Locks

Hydraulic drives located close to docks, rivers & canals water require high levels of reliability, corrosion protection and environmental compatibility. These requirements are fulfilled using modern piston rod coatings such as Hunger Ceraplate and Ultraplate coating, combined with special Hunger seal and guiding elements and environment friendly hydraulic fluids and by using Hunger stainless steel maintenance free spherical bearings.

Hydro Electric Power Stations

Hunger cylinders are employed in many hydroelectric power plants worldwide for the operation of turbine intake gates to control turbine speed. The cylinders must provide a reliable load holding function and must be capable of controlled interruption of the water flow at a high speed to prevent turbine breakdown.
