RESTON®PENDULUM – Seismic isolators

RESTON®PENDULUM – Seismic isolators

mageba seismic isolator RESTON-PENDULUM bearings are based on the functional principle of a pendulum. They allow a structure to become horizontally displaced during an earthquake, with seismic energy being dissipated by the friction betw ... [more]

RESTON®POT – Pot Bearings

RESTON®POT – Pot Bearings

mageba Pot Bearings are durable bearings that can be used in many situations, whether in big or small bridges, or a variety of engineering structures.

RESTON®SA – Hydraulic dampers

RESTON®SA – Hydraulic dampers

Under normal circumstances, Hydraulic Shock Absorbers allow free movements of the bridge structure. Under shock impact, e.g. due to earthquakes, high braking loads or strong winds, they function temporarily as elastic damping connections.

TENSA®MODULAR LR & LR-LS – Modular expansion joints

TENSA®MODULAR LR & LR-LS – Modular expansion joints

Modular Expansion Joints can be constructed for any movements, from about 100 mm up to 2,000 mm and more. They allow movements in all 3 directions and rotations around all 3 axes.
