Round Manhole Trench Shield


Round Manhole Trench Shield

GME’s Manhole Trench Shields are designed to allow a pipe job to progress along with little interruption or delay. The idea behind these trench boxes is to use them in conjunction with trench shields on a job-site. When the job lead to a manhole structure, insert the Manhole Trench Box and continue on with the pipe work on the other side.


The GME Shields are available as a; Square Manhole, Round Manhole (providing complete protection on all sides), Octagon Manhole and a 4-Sided Manhole Shield (WTB Series). All trench shields are designed by GME to be used with in the 40,000 to 60,000 lb range.


The Round Manhole Shields are specially designed for personal protection during manhole installations and repair work. High strength steel walls, welded securely to rigid steel top and bottom framing. Optional replaceable cut-outs allow for clearance of utility lines.
