SEVENCRANE se bo udeležil EXPONOR CHILE od 3. do 6. junija 2024.

Portalni žerjav z enim nosilcem je v glavnem sestavljen iz mostu (glavni nosilec), štirih opornikov, spodnjega nosilca, pogonske naprave za voziček, električnega krmiljenja, električnega dvigala itd. Mostni okvir (glavni nosilec) portalnega žerjava z enim žarkom je na splošno škatlasto strukturo, zvarjeno z jeklenimi ploščami. Dno glavnega nosilca je opremljeno s tirnico I-nosilca za delovanje električnega dvigala. Lahko se uporablja tudi za glavni nosilec portalnih žerjavov z velikim razponom, ki delajo na prostem. Nosilna konstrukcija, oblikovana z varjenjem profilnega jekla, ima visoko togost (zlasti vodoravno togost), majhno težo, majhno privetrno območje in ima velike gospodarske koristi. Vendar je izdelava in varjenje te konstrukcije bolj zapletena in težavna od škatlaste strukture.

Veliki portalni žerjavi so najpogostejša dvižna in manipulativna oprema, ki se uporablja v industriji in gradbeništvu. Pogosto se uporabljajo za dvigovanje težkih in premikanje v industrijskih okoljih, kot so pristanišča, gradbišča in proizvodni obrati. Portalni žerjavi so opremljeni z dvižnim mehanizmom, ki lahko dviguje in spušča težke predmete. Mehanizem običajno vključuje sistem žerjava ali vitla, ki je lahko električni, hidravlični ali drugače gnan, odvisno od zasnove žerjava. Zanj je značilna visoka, toga jeklena konstrukcija, ki se razteza čez območje in je na obeh straneh podprta z nogami ali stebri.

The mobile girder rail gantry crane consists of the main beam, rigid and flexible door legs, operating trolley, lifting mechanism, cart operating mechanism, electrical system, operating cab, etc. According to the yard operation process, the cantilever can be extended in the direction of the single door leg or the double door leg to become a single cantilever or double cantilever model, and if it is not extended, it will be a non-cantilever model. According to the location, container storage and transportation process, and loading and unloading vehicles (container trucks or railway vehicles), confirm the selection of different structural methods without cantilever, single cantilever, and double cantilever.

Warehouse gantry cranes are widely used in factories, construction sites, and material handling plants to lift and transport materials. There are different types of this crane such as semi-gantry crane, single-girder gantry crane, durable double-girder gantry crane, efficient mobile crane, warehouse rail-mounted container gantry crane. Customers can choose the appropriate type according to actual needs. SEVENCRANE, a professional crane manufacturer, provides cranes with excellent performance and low prices. Choosing our company is more efficient and cost-effective.

The warehouse gantry crane produced by SEVENCRANE has an Automatic Storage and Retrieval System (ASRS), which is a warehouse stacker used for elevated shelf systems. The AS/RS lifting system uses automated technology to store and retrieve pallets. The warehouse crane system is mainly composed of three operating mechanisms: lifting mechanism, crane operating mechanism, and trolley operating mechanism.
