Function：If we are restricted by the geographic conditions such as
the ground is cramped, and we can not arrange the drawing wire,
this equipment can be fit for this circumstance. The section is a
trapezoid which is narrow-end-up mold without wire. We can arrange
trimmed hammer in the tower, ect.
Trait：
The section is a trapezoid, which is narrow-end-up mold without
wire, artistically laid out and orderly placed.
According to the lay out of the back anchor, the vertical steel
tower can be fit into two kinds: with the back anchor and without
back anchor. The difference is that the vertical steel tower
without back anchor mainly subjected to the pull from the main
cable way. The force analysis of the steel tower is the main angle
iron whice is nearly the bankside to bear the pressure The removed
bank side subjected to the pull, so the concrete fundament is
relatively lager, the main angle bar and the connecting angel are
also relatively rougher, and the top slab and the support clock are
relatively thicker.
The other type mainly subjected to the pressure come from the main
wire cable. As a consequent, the concrete fundament is relatively
smaller, the main angle bar and the connecting angel are also
relatively thinner, and the top slab and the plate are relatively
slimmer.
