For guarantee Overhead crane of normal of work and in any location of positioning, each institutions Shang are set has security device, as in motor and reducer of high-speed axis Shang layout, by brake and brake round coupling composition, brake for often closed type, power Shi brake gate w open, power Shi closed, can makes was hanging of weights in lifting of any location stop not moving, makes size car run institutions stop running, achieved accurate in place.
Overhead crane hoisting mechanism is by electric motor, speed reducer, drum group, and wire ropes, pulleys, hooks set of components, under the driving torque of the motor, hook up or down, is lifting weights and with it rising or falling. Trolley run establishments and traveling by motor, reducer, coupling, wheel sets and other components, drive torque produced by the motor through reducer, coupling operation of the wheel is made in two directions, trolley and bridge can be realize the purpose of movement from one place to another, is lifting weights to achieve stereo location of displacement.
Except brake device outside, Overhead crane of up liters institutions also device limited bit switch, overload limit device, size car are with limited bit switch, circuit in the set has had current protection, and lost pressure protection, and deficiency items protection, and zero bit protection, and emergency switch, and main isolation switch, and warehouse mouth door lock switch, and Bell tips, security device, to ensure crane of normal work and related personnel of personal security.
