TS-HM-150-ZD

Data Sheet

Area of Application

The TS-HM-150-ZD is a shallow landslide barrier with a hinged connection to the base plate requiring upslope retaining ropes to support the post head. It has been 1:1 scale tested with multiple impact events.

Rope Guidances

The upper and lower bearing ropes are led through a rope guidance that is integrated on each post head and base plate. A similar guidance is used for the middle ropes. Each guidance provides large curved surfaces to help protect the ropes and allow unobstructed movement. The guidance is designed to be robust and with no movable parts in order to ensure longevity and zero maintenance.

Integrated Ladder

Each post has an integrated ladder composed of rungs spaced at 50 cm intervals in the webbing of the I-beam. The ladder assists in the installation of the fence as well as routine inspection and maintenance.

Retaining Rope Anchorage

The post head is secured using retaining ropes that lead to an upslope anchor in the middle of the field on either side of the post. This gives side-to-side stability of the post as well as the ability to lead forces into the ground. One anchor is shared between two posts. For this system, there are no brake elements on the retaining ropes.

Lateral Anchorage

Lateral anchoring or internal anchoring of long sections of fences are achieved normally with two anchors having the main bearing ropes and the middle ropes attached with brakes, thimbles and shackles. Brake elements on the middle ropes allow for more elongation than the upper and lower brakes to maximize energy absorption while maintaining a large residual height.

GDV Brake Element

The GDV series of brake elements are steel profiles with a roller which is pulled along its length when a force is applied, causing deformation. The gauge and length of the steel strip can be altered to control the amount of energy absorbed and the total displacement. These brakes are highly efficient and require minimal off-set from the posts.

Omega-Net

The primary net material used in Trumer systems is called the Omega-Net. It is a steel cable net made from spiral rope that has thick individual wires to resist abrasion. The strands of rope are pre-bent into arcs resembling an omega shape and then woven together to make the net. This process yields an extremely strong net with high flexibility and energy absorption characteristics.
