Background technique

In tight line construction, it is often necessary to encounter various obstacles such as crossing roads, railways, communication and broadcasting lines, and power lines. In order to keep the conductors from being damaged and not affect the safe operation of the spanned objects, spanning frames should be set up at these crossing places before setting out the wires, so that the conductors can pass safely and smoothly. There are several ways to set up the spanning frame: general erection, non-stop erection and high-altitude crossing.

In crossing high-speed construction, the traditional lifting system generally adopts a spanning frame to span and seal the net on the top of the spanning frame, but this type of spanning frame can only prevent the load of the conductor under loose working conditions, such as a "running line" accident situation, then the straddle frame cannot be prevented.
