How do i determine the load on a door hinge.

Hinges for doors of this type often carry quite a load. If using pivot hinges at the ends of the door usually the upper hinge female is detached from the male for a few millimeters as it is free to get downward. Although the main force on the door is vertical the load on the hinges also has a horizontal component in the plane of the door. A full overlay door covers all or nearly all of the front edge of the cabinet.

Radial load fdoor x d1 fext x d2 dhinge multiply fdoor with the difference between dhinge and d1. Radial load hinge one fdoor x dhinge d1 dhinge. This overlay type typically is used for doors at the ends of a cabinet. Multiply fdoor by d1 and divide by dhinge.

One way to calculate this is to assume the lower hinge pin is fixed and figure the torque on that hinge pin so that the top hinge pin 62 away provides all the torque. This hinge will allow the door to cover half of the partition wall or approximately 3 8. As a further consequence of this effect the total weight of the door will load on the top hinge. A basic guideline for buying a gate hinge would be a gate door that is 5 feet high 3 feet wide and 55 pounds would be considered an average size door while one that is 6 feet high 4 feet wide and 132 pounds would be considered heavy.

That s force distance so 62 torque force on pin 63750 in lbs. A wider door will need more load bearing support for stability. The distance between the hinges is bigger than the door height diffmm mm too much n 1 i with the help of the dirak hinge calculator you will get recommendations for suitable hinges based on the information you have entered. Doors up to 60 need two hinges.

The hinge height required is determined by the door thickness and the door width. In stock and ready to ship. The center of gravity of the door is cantilevered off the hinges. Choose from our selection of load rated hinges including butt hinges entry door hinges and more.

The width of the door is important because it affects the weight of the door. As a general rule you will want to use one hinge per every 30 of door or fraction thereof.
