Hydraulic Devices

Hydraulic devices use fluid pressure to generate mechanical force and motion. They operate based on Pascal’s Law, enabling efficient power transmission. Common applications include hydraulic presses, lifts, brakes, and heavy machinery. These systems offer high power, precise control, and durability, making them essential in industries like construction, automotive, and manufacturing.

Hydraulic Dampers

MSIL hydraulic dampers efficiently dissipate energy by directing hydraulic fluid through precision-engineered orifices or valves under high pressure. Designed to enhance structural resilience during dynamic events such as earthquakes, these dampers provide optimized fluid flow control, ensuring smooth relative motion while limiting response forces to a predefined maximum level. The velocity-dependent response force can be fine-tuned with customizable damping exponents (α = 0.04-2.0), catering to specific structural requirements with high precision.

Minimal Resistance During Thermal Expansion – Offers imperceptible resistance below 3% of the nominal response force, ensuring structural flexibility.
Leak-Proof Design – A robust triple-sealing and pressure-limiting system prevent fluid leakage, enhancing reliability.
Hybrid Functionalities – Features optional fuse functions, lock-up mechanisms, and damping functions for versatile applications.
Adjustable Blocking Function – Allows blocking from as low as 0.1 mm/s to 0.5 mm/s for controlled motion restriction.
Rapid Response Time – High internal fluid rigidity ensures instantaneous force activation during seismic events.
Maintenance-Free Operation – Designed for long-term performance without the need for regular maintenance.
Wide Operating Temperature Range – Reliable functionality in extreme conditions from -50°C to +80°C.
Stable Internal Pressure – Heat-induced fluid expansion does not lead to increased internal pressure, maintaining system integrity.
Certified Quality – CE marking available, ensuring compliance with international standards.

Tuned Mass Dampers (TMD)

Slender, overhanging structures often experience vibrations due to their low inherent damping, typically ranging from 0.5% to 1%. Without effective damping solutions, excessive vibration amplitudes can impact structural integrity, reduce comfort, and accelerate material fatigue.

MSIL Tuned Mass Dampers (TMDs) are engineered to mitigate such vibrations with precision. Each TMD is custom-designed based on the specific structural requirements, utilizing a spring-mass system. The spring is fine-tuned to match the natural frequency of the structure, while the mass is carefully determined based on the modal mass of the relevant mode.

MSIL TMDs effectively reduce vibrations caused by wind and seismic activity in high-rise buildings, towers, bridges, and industrial structures, ensuring enhanced durability, safety, and occupant comfort.

Shock Transmission Units

MSIL Shock Transmission Units are advanced hydraulic safety devices engineered to enhance structural stability by locking under sudden dynamic forces such as seismic shocks or abrupt braking on bridges. These units effectively clamp the structure during high-impact events while permitting slow, natural movements with minimal resistance under normal conditions. Additionally, MSIL Load Limiters are designed to regulate reaction forces through velocity-controlled oil flow, preventing excessive stress on the structure. By integrating these technologies, MSIL ensures superior protection against extreme displacement forces, significantly reducing the risk of structural damage.
