The underslung overhead crane is used in conjunction with the CD1, MD1 electric hoist to become a light and small crane that runs on rails. Used in machinery, assembly site, warehouses, and other places
The LX underslung overhead crane is suitable for working under the conditions of working level A3～A4, working environment temperature -25℃～+40℃, relative humidity ≤85% and no flammable, explosive and corrosive medium environment. The lifting weight is 0.5 to 10 tons, and the span is 3 to 22.5 meters.
The product has the advantages of compact structure, good rigidity, easy operation, low noise, safety and reliability, and beautiful appearance.
The main components are: bridge frame, crane operating mechanism, electric hoist, and electronic control system.
To install an underslung cranes, the roof structure must have the ability to withstand the weight that imposed by the underslung cranes itself and the load. So, before you make the final decision to purchase an single girder underslung cranes, you need to consult with our engineers to make sure that every detail is considered in order to avoid any convenience.
Simply attached to the existing roof structure, this special kind cranes eliminate the need for runway support columns. This way, the entire building floor area is available for production. Peripheral areas of the workshop can be served by using the girder overhangs to extend the travel range of the hoist trolley beyond the runways. Optional latching devices make it possible to transfer the hoist trolley from the crane girder to a branch track and back without having to deposit the load.
The electric suspension crane bridge frame is mainly composed of main beam and end beam device. The main beam is the main load-bearing component of the hoist crane, and its lower flange is the electric hoist running track.
Electric suspension cranes are generally designed with 500mm, 750mm, 1000mm cantilevers according to different spans. When the electric hoist is fully loaded to the cantilever end, negative wheel pressure is not allowed on the opposite side.
The end beam device is located directly above the span of the two ends of the main beam, and is connected to the main beam through a single-hole hinged connecting plate. Rubber buffers are installed at both ends of the beam to avoid structural damage due to collision.
The balance shaft connection structure is adopted between the main beam and the end beam, which is simple in structure, convenient to install, and convenient for transportation and storage.
The electric suspension overhead crane trolley running mechanism consists of two sets electric trolleys and two sets driven trolleys, which are connected to the end beam connecting plate by two bolts under the wall panel.
The motor adopts ZDY series conical rotor brake motor. The motor has the characteristics of good heat dissipation, long service life, safety and reliability.
The body and cover of the drive unit are cast from gray iron HT200 with good anti-vibration performance. The gears and gear shafts are 40Cr forgings, and the hardness is HB235～269.
The wheel set is formed by die forging of 45# steel, and the heat treatment hardness is 300～380HB.
The wheel axle is made of 45# steel, and the heat treatment hardness is 235～269HB.
Electric hoist is to be used on underslung overhead crane, each electric hoist will perform dynamic and static load test, rise and drop pressure tests. The baking paint process is adopted to enhance the adhesion of the paint film and improve the appearance quality. Assembly line ensures product quality.
Pendant panel, Remote control. The crane can also be equipped with two sets of operating devices, namely: ground + remote control .
However, due to safety issues, the two operating modes can only be switched and cannot be used at the same time.
The control circuit voltage is generally AC 36V safe voltage.
Crane electrical equipment can ensure that the crane has safe, accurate and reliable transmission performance, monitoring performance and protection performance.
According to customer requirements, the power supply can be designed as a three-phase electrical control system below 690V and a frequency of 50-60HZ.
