BHI Hydraulic crane buffers

With THRAIL energy absorbing hydraulic bumpers

THRAIL and  international’s bumpers/buffers are designed for the harshest heavy-duty applications. Featuring a fatigue-less gas return spring and the most efficient fluid metering pin system available on the market, THRAIL/’s hydraulic bumper controls the deceleration of rail-mounted material handling equipment. Regardless of crane size or travel speed, THRAIL and  have come up with a solution providing the requested protection to control-stop all rail-mounted equipment whilst minimizing the end forces resulting from impact.Moreover, THRAIL also supplies a line of hydraulic bumpers and rubber buffers for much smaller moving equipment.

 

With the increased travel speeds of today’s container sts cranes, automated overhead and gantry cranes and high speed transfer cars the need for energy absorbing hydraulic bumpers (also known as buffers depending on your location) is greater than ever.

End stops are commonplace in docks and ports, at the end of rails accommodating cranes and railway lines delivering bulk material or cargo to a port. End stops are also used in factories and steel mills with cranes and major machinery to remove some of the high stresses endured by the buildings when cranes reach their destination. Very occasionally, moving equipment can fail to stop or slow down sufficiently, resulting in a risk of collision or overriding the end of the platform/line. Fitting efficient and effective end stops protects passengers, rolling stock and infrastructures in the rare events that trains or cranes fail to stop.
