Very good camera, well studied. It comprises a bracket carrying the door and a lever hinged on a central pivot. 1- square with the door: * Its horizontal part (4 mm thick) is treated slip and size 5 * 8 cm suited (thickness of a door 4 cm); * Its vertical part is covered with felt to protect the face of the door. It remains vertical well when lifting with an integrated lever parallelogram lift door, * This bracket can rotate left to right, which, combined with the rotation of the lever around the central pivot, allows to translate the door to the hinges (the lift door Roughneck 32500 available from Amazon does not have this joint) 2 - lift capacity: average leverage arm between the foot of the operator and the door is 1.3, one for a 70 kg operator a maximum lifting capacity of 90 kg. Remarks: * Other websites indicate a lever ratio of 1.7: it assumes that the foot of the operator is applied to the extreme end of the lift door and the door of zero thickness is applied against the vertical part of the The support bracket (unrealistic) * Other sites indicate a lifting capacity of 200 kg: it is the strength of the product. To lift that much weight, the operator should be a sumo 150 kg! 3 - Lifting height measured 83 mm (some websites indicate 75 mm) 4 - Soil protection: this raises holder has: * A central pivot whose base is sheathed rubber to protect the soil and be non-slip, * A rubber stopper in the end of the lever 5 - Manufacturing Spanish by Virutex under Reference EP70P 6 - Site: [...]
