3 ton LDY Metallurgical Electric Single Girder Overhead Crane With Span 13.5 Meters – Height 9 Meters

Overall structure sketch

Supply Scope

Our company mainly manufactures metallurgy cranes with lifting capacity of 1-10t, span of 7.5m-28.5m, lifting height of 1m-30m, working class(A6), also can design and manufacture according to requirements.

Applications

1. Matched with metallurgy hoist, to do interval and cycle work.
2. It is an important equipments to improve efficiency in modern industrial metallurgy and casting sites.
3. Crane assembly and test accord with No. 375, 2007 document
4. Banned used in inflammable, explosive corrosive medium environment.

Working Conditions

It is applicable in the temperature of -25℃～+60℃, Humidity≤85%, the temperature is below +60℃, humidity ≤50%, Altitude below 2000m, Power is 3-phase 380v 50HZ(also can be customized according to customer's requirements).

Structure & Feature

Mainly composed of bridge(metal), crane traveling mechanism, metallurgy hoist and electrical equipments.

Bridge

1. Use for supporting the crane and longitudinal traverse.
2. Be composed of main girder, end truck and connector, the three parts
3. The main girder is composed of high quality molding and stamping I-beam and U-Steel.
4. Adapts special thermal protection process below the main girder.
5. Steel quality is Q235B or Q345B(international Fe37 or Fe52).
6. The end truck is welded by rectangular tube or high quality steel plate.
7. The connecting between main girder and end truck adapts bolts suspension or sitting structure, easy for transportation.

Crane traveling mechanism

1. Separate driving
2. Driving and braking are completed by tapered rotor motor, can reduce damage to rail because of wheel skew or deflection.

Metallurgy hoist（It has an independent specification）

Electric

1. Lifting and traveling can be controlled separately, working separately or at the same time.
2. The power supply of trolley moving adapts thermostability cable.
3. Optional power supply ways:angle steel slide touch line, safe slide touch line, soft cable slide touch line
4. Control ways is ground control, Considering safety, advise to adapts remote control.
5. Through pressing the button switch, makes the contactor cut in or cut off the power, the electric components of main circuit and control circuit are less, easy maintenance.
6. There is thermal protective device outside the motor.
