The correct method of operation: run organization in the range of short-distance running, should be selected according to the specific circumstances of the controller should be in the position of the handle. If you run institutions operating within long-distance range, must take control handle stepwise to the last stage, the motor is running at high speed, Hohhot double girder crane, so that both the motor is good, but the work efficiency too high, and saving electricity. When hanging hook hoisting mechanism has objects, control handle back to the rise in the last stage of the zero position, must remain slightly (1 second) in the middle of each range. As for the heavy load, the handle on the second level should remain one more would be better, thus reducing the vibration when stopping hook. Crane starting to have a smooth and by levels of acceleration. Lifting mechanism for each file conversion time of 1-2 seconds, run the agency each file conversion time is not less than three seconds. (4) high manufacturing precision, fine, good looks small frame uses large CNC Boring and Milling overall processing each trolley car seat and reaming, reduce manufacturing variations welding process, manufacture of high precision, improve the various components installation accuracy, avoid eating the rail car and three-wheel phenomenon. Bridge with the overall drilling process as a whole draw lines, 32 tons of double girder crane, end beam coupling reaming, reaming carts sets the frame are boring overall, improve the assembly precision bridge and traveling mechanism to avoid carts skew and three-wheel phenomenon. (5) Electrical control of high precision, perfect protection of the bridge crane AC inverter + PLC program control, dual-beam crane companies, agencies motion accuracy is less than 5mm, at the same time, with a complete mechanical and electrical protection devices, such as main and auxiliary hook overload limiter, main and auxiliary hook height limiters, running institutional settings proximity switch deceleration, limit switches and the mechanical end stop buffer stop. (6) series, modular design days of the company's products have become modular and serialization. All new products are designed in a mature product developed on the basis of reliable performance. (7) frequency control, smooth starting and braking; can be equipped with anti-sway technology, lifting more secure. All agencies using frequency control, starting and braking smoothly without impact, increase safety crane work and can improve productivity. If the user needs, the crane can be added fortification swing function: while working hoist no swing, positioning accuracy, automatic reset, enhance efficiency, improve work safety. 32 t double-girder crane _ generous heavy (Online) _ Hohhot double girder crane provided by generous heavy machinery Co., Ltd., Henan Province.
