Guillotines

Standard Size: 36" High by 48" Wide

The overall dimensions are approximately 14 feet high to the top of the hydraulic cylinder, approximately 6 feet wide and approximately 6 feet long. It is powered by an 8" hydraulic cylinder and a 40 HP hydraulic pump. The hydraulic pump is tucked underneath the work table of the machine. The machine has heavy guards, guarding the blade. The hydraulic cylinder is electrically operated by two push buttons connected in such a way so that the operator must keep both hands on the buttons while the blade is moving down for safety reasons. The two up-rights of the machine are made of 8" x 8" x 1/2" thick structural tubing reinforced by 1" x 6" plates on the inside where the knife holder rides. The cross members (where the cylinder is mounted) are made of 18" ship channel having 3/4" x 3" vertical ribs and boxed in with 3/8" plate.
