One of the main advantages of the Parallel Single Slide Rail Shoring with H-Rolling Frame is that even very long pipes can be installed.
The H-Rolling frames get positioned alternately. One H-frame must be lowered down as far as possible; the next H-frame should be in an upper position. Then the long pipe has to be placed down in the range of the lower H-frame and moved horizontally underneath the upper H-frame for final positioning.
The H-Rolling frame is a vertically moveable frame, which flexibly adjusts in height for a pipe clearance of up to 2.60 m. The system can be used for a trench width from 1.05 m to 7.05 m. In order to achieve the required trench width, several frame extensions can be flanged and screwed behind each other.
The Single Slide Rail has a one track guidance for the insertion of the shoring plates. The plates are equipped with special T-shaped side adapters to slide into the rail, ensuring a positive connection. Thus, only one base and one top extension plate can be inserted for a maximum trench depth of up to ~ 3.80 m.
The slide rail plates and bolts used are identical in all our Slide Rail Systems enabling a high level of flexibility and compatibility.
The standard length of the Slide Rail plates is 2.00 to 5.00 m; however, the 3.50 m long plate is the most common for this system.
