The key to smooth, friction-free running lies in the end trucks. G-Rail™ end trucks are rigid, as opposed to articulating, that is, the bridge crane cannot skew with respect to the runways. This means that the whole bridge moves along evenly, with a decreased “pendulum effect”.
At Givens Lifting Systems, our end trucks are machined from aluminum, not welded. This allows for an accurate and square-fit, eliminating the possibility of binding. We ensure that the guide wheels at either end of the overhead crane are properly fitted to reduce friction.
