40 Ton Overhead Crane - Double Girder Grab Crane for Sale America

grab crane for A Paper Plant

Bulk material handling around the clock – outdoors and in all weathers. DQCRANES overhead traveling cranes can meet the operating requirements for an paper factory in America. This heavy duty crane aims to blend the incoming materials and to serve the furnaces according to schedule. 

40 Ton overhead crane for Sale to America

• As a famous paper manufacturer in North America, the client operates a plant with four machines to produce paper for printing newspapers and magazines. Two furnaces are supplied with fuels to generate the steam needed in the production process.
• The two sets of double-girder overhead travelling cranes supplied from DQCRANES, has a load capacity of 40 tons, span 22.25 m and travels on a runway at a height of approximately 10.688 m. It clears shredded wood chips from two tipping positions and first heaps them in the storage area. Using a motor-powered orange peel grab, which has a capacity of up to 8 m3 thanks to its enclosed design, this 40 ton overhead crane also picks up deliveries of slurry and distributes it over the entire storage area.
• This 40 ton bridge crane works around the clock, also operating smoothly down to temperatures of 20 degrees below zero. The electric components of the crane installation are installed in an insulated and heated container on the crane bridge. Eight motors for the long-travel motions and four for cross-travel ensure that the crane positions exactly, even in strong wind conditions. If the wind force 10, the bridge cranes will be switched off and mechanically locked.
• In addition, the double girder overhead crane adopts an eight-wheel structure, not only allows the end carriage to be disassembled into three sections, which is convenient for transportation, but also disperses the wheel pressure, which greatly extends the life of the track, rail bearing beam, and column, and facilitates adding new crane on the same span in the future.

Grab Crane Application

Grab crane is the equipment that is commonly used in industrial site to load and unload powder (bulk) goods in 3-dimensional space. Motions of grab crane in horizontal lateral and longitudinal directions are realized respectively by the crane and trolley, which are generally called traveling system; vertical motions of grab crane are completed by the lifting motor responsible for lifting motion and the open and close motor responsible for grab bucket opening and closing (throwing and grabbing). In general, the supporting motor of grab crane is wound-rotor AC asynchronous motor, which uses series-resistance speed regulation and relay-contact control mode in most cases. Since the motor consumes lot of energies when it operates at a low speed, and has flexible mechanical characteristics, small speed regulation range, low efficiency and high fault rate, it is a good choice to use a frequency converter together with it. 

Grab Crane Process Characteristic

• The low-frequency starting torque is big, speed is smooth and has high accuracy;
• It is convenience to operate, the failure rate in use is low;
• When there is a heavy haul, start-stop in halfway is normal, smoothly and do not slide;
• Raising, making and braking torque output balanced, contribute balanced, the bucket does not open when moving;
• Positioning accuracy is high, with good operating performance. 

Applicable Scenario

• Similar application: Grab Overhead Crane, Grab gantry crane and Grab jib crane, etc..
• Applicable industries: Metallurgy, petrochemical, logistics, Paper Plant, power plant, mining, building material and port, etc..
