PURPOSE:To allow easy and quick metal fixing work while reducing the number of workers by mounting an X-axis positioning body, a Y-axis positioning body, and an elevating/lowering means on a truck and disposing metal supporting members at the upper end of the elevating/lowering means thereby eliminating the worker for holding the metal. CONSTITUTION:The body 3 of fixing device is moved immediately below an anchor bolt protruding from ceiling face by means of casters 22 of a truck 1. A suspension metal 8 is supported by a metal supporting member 6 at the tip of an elevating/lowering means 7. An X-axis positioning body 4 and a Y-axis positioning body 5 are then driven to be stopped at appropriate positions for aligning a bolt hole made through the suspension metal 8 with the anchor bolt protruding from the ceiling. The elevating/lowering means 7 is then elevated thus inserting the anchor bolt into the bolt hole of the suspension metal 8. While keeping that state, a worker tightens 8 washer and 8 nut from the end of the anchor bolt. This constitution allows one worker to secure the suspension metal 8 to the ceiling. |
