Tree shaker comprises a construction, which have a front end engaging two arms for gripping a tree. It consists of two shafts. A first shaft having a first weight is rotatably engaged by the construction and is rotated by a first motor a first weight connected to or integrally formed with the first shaft and a second shaft having a second weight is rotatably engaged by the construction and is rotated by a second motor. The first and second shafts being coaxial such that one of them is internally located relative to the other and a stopping mechanism is connected to one of the weights for restricting the relative orientation of the weights to a maximum of 180.degree. one relative to the other & to a minimum of a close contact between one another.

Trench and sump lining systems are typically applied at a minimum 1/8″ thickness to the interior of tanks, trenches and other surfaces.  They are designed to withstand a broad range of chemical exposures and sliding abrasion. 

Trench Fill Boxes are included in midland machineries. It is strike-off to 30″ below grade. It is available with an edge drain guide tube keeps drain tube from getting crushed by aggregate.

Trench Rollers provides smooth operation with the powerful water-cooled, electric start & cylinder diesel engines, which is equipped with radio remote control and charged at the roller. It is used to compact soil being refilled into a pipe or cable trench. This roller is used in trench operations having a compacting roller of a width not less than 15 inches (380 mm). It is equipped with a leveling mechanism to maintain the compacting surface of the roller in the desired plane while compacting surfaces below the edge of the old pavement.
