A deviation quantity is generated between the first and second trolley cranes, a correction signal proportional to the magnitude of this deviation quantity is outputted from a position electricity converter 32. This signal is inputted to the second acceleration/deceleration regulator 32b. The second trolley crane starts the slave operation by optimumly shortening the integrated time of the second acceleration/deceleration regulator 32b. On the other hand, the harmonious movement when the cargo handling is performed by the second gantry crane is likewise controlled by a relay 45a.

IPC: C22C38/00
Filed: 1979-09-21
Abstract: PURPOSE: To provide heat-resisting steel having improved impact value without lowering strength, by adding a very small quantities of Nb, Zr, to SUS403 steel.  
     CONSTITUTION: Heat-resisting steel contg. 0.08W0.25% C, ≤1.5% Si, ≤1.5% Mn, ≤1.0% Ni, 10.0W14.0% Cr, ≤2.0% Mo, ≤1.0W%, ≤0.5% V. It is an essential condition for said steel to contain 0.02W0.5% (Nb+Zr), provided that ≤0.01% Nb, ≤0.01% Zr. In said composition, Nb and Mo are particularly strong carbide- forming elements, and improve high temp. strength and temper resistance, in addition, prevent formation of coarse crystal grains, as a result, improving remarkably toughness by dispersion and precipitation of ine structure of NbC. Zr contributes to form fine crystal grains, hence simultaneous addition of Nb and Zr allows particularly to form fine crystal grains, hence Zr is effective in improving the toughness by strengthening the intergranular boundary.
