Profile: Griswold Machine & Engineering, Inc. is a manufacturer and supplier of trench shielding and trench shoring products. We specialize in product engineering and industry development. Our bedding boxes are designed for clean sweep access by the excavator bucket. Four styles of bedding boxes are available (standard, heavy duty, light duty, and Easy Lift), to handle from four to fifteen cubic yards of bedding material such as gravel or washed rock. Custom designs and modifications can also be produced to meet specific bedding box needs. The standard bedding box unit features rugged steel welded construction, fully re-inforced at all points of stress. The top frame is further strengthened by an inner core of hardwood. This unit is constructed of 1/4" sides and ends, and the bottom surface is smooth; fabricated of 1/2" steel plate, with wear strips on the inside to guard against damage by bucket teeth. Low 44" profile allows dump truck to fill the box from either end or side.
