PURPOSE:To reinforce the strength of lifting the iron core by forming a penetrating hole for lifting the iron core at the top of a reinforcing plate and upper iron core clamping bracket or of the upper iron core clamping bracket and strap and lifting the iron core. CONSTITUTION:The legs 1a of the iron core are extended at the top upwardly. The upper iron core clamping bracket 2 is increased in width. The legs 1a and the bracket 2 are fitted through connecting pins 4. The penetrating hole 6 for lifting the iron core 1 is formed at the tops of the bracket 2 and the strap 3. Since the thickness of the hole 6 is the sum of the bracket 2 and the strap 3, the strength of the hole 6 can be increased. The lifting load is shared at the conneting pin 4 and directly at the strap 3. |
