Product Description Product Description20Ton 30m Port Use Electric Lattice Boom Rail-mounted Mobile Gantry CraneOEM & ODMCertificate: CCS, ABS, BV, RMRS, DNV, LR, RINA, CE, ISO9001Rail-mounted Mobile Gantry Crane with Lattice Boom The crane drives the boom to complete pitching movements through drums, steel wire ropes, and pulley blocks, realizing thelifting and lowering of cargo; the horizontal movement of cargo is achieved through the rotation of the slewing mechanismwithin a range of 0-360 degrees, and it can be used in conjunction with specialized lifting tools, such as grabs, spreaders,and lifting beams.To reduce the weight of the crane while completing high loads, our crane adopts a lattice-type boom, which lightens the weighttraditional box-type rigid boom crane.When this lightweight and efficient crane is transferred from the ship to the port (from sea to land), it achieves moreconvenient and flexible use, we have designed movable "feet" (equipped with rubber tires or wheels moving along tracks),enabling it to move to land-based places such as ports and terminals, providing efficient and convenient solutions forcargo loading and unloading in ports, terminals, and other scenarios.Detailed PhotosFeatures1. Core Transmission Principle- Mechanical Transmission: Through the combination of steel wire ropes winding around drums and pulley blocks,the rotational movement of the drum is converted into the pitching linear movement of the boom.- Slewing Mechanism: Adopts gear or ring gear transmission to achieve full-circumferential (0-400°) rotation of the cranemain body, covering a wider operating range.2. Land Adaptation Innovations- Mobile Chassis: Rubber tires are suitable for short-distance movement on flexible road surfaces, while rail wheels are suitablefor long-distance, precise positioning on fixed tracks, enhancing site adaptability.- Functional Extension: Expanding from cargo loading and unloading scenarios on ship decks to integrated horizontaltransportation + vertical lifting operations at inland ports, reducing cargo transfer links.Applications Rail-mounted Mobile Gantry Crane with Lattice boom is commonly used in heavy-duty cargo loading/unloading andhandling scenarios requiring fixed-track movements, such as ports, docks, shipyards, and large logistics warehousing centers.It is particularly suitable for joint operations integrating ship decks and land tracks.DESIGN DRAWINGWe can design and produce cranes according to operational scenarios and specific requirements, accept non-standard customization, and allow customers to choose the required functions.Design phaseProduct ParametersTechnical characteristic parameterTrackClassificationM5Track modelP50Travel speed20 m/minMotor modelYZPF160M-6Wheel diameterΦ550 mmPower7.5 KWHardness of tooth surface HB=300-380Rotate speed965rpmMax. wheel pressure240KNGauge/Base distance10.5m·10.5m40T 30m Hydraulic Portal Gantry Crane(Rail-mounted Mobile Gantry Crane with Lattice Boom )SWL28t(Under the sling)10t(Sling no load)25t(Grab)40t(Hook)Working rangeMin/Max.7m/30mHeightOn track/DownOn:20m Down:15mWork speedHoisting25 m/min40 m/min30 m/min 20 m/min ,40 m/min (< 10t)Luffing80sRotate0.7r/minTrack 0.7r/minMotor PowerHydraulic system250kW(40%Duty Cycle)Track 7.5kWx8Weight240t Partial list of our crane productsImportantIt is important to know the intended application of your marine crane requirement. Below, you will find a general list of topics that we will discuss to manufacture a marine crane to your specifications accurately. * What are you planning to lift with your marine crane? * What is your desired load? * What is your desired reach? * Are you interested in which kind of marine cranes? * What are your environmental conditions? * What kind of controls would you like? * What is your drive system preference, electric hydraulic, diesel hydraulic, air pressure, or existing power system? * What classification does your marine crane require? ABS, Bureau Veritas, Lloyd's?CertificationCutting and Welding of Crane Steel PlatesCooperationWe started by meeting each other, visiting factories, discussing requirements, giving solutions, confirming orders, discussing details, and completing deliveries. We became not only business partners but also friends in life. It was a pleasant and meaningful journey. FAQ 1. Are you a manufacturer? Our factory is staffed with skilled technicians on-site, complemented by our trading company.2. Are your products customized? Yes, because of the different working conditions, all our products are customized depending on detail requirements! So if you give us more information about the lift capacity, span, lift height, power source, and other specials, we will give you a very quick quote! 3. What information should I provide when inquiring? The more information you provide, the more accurate solution we can prepare for you! The information such as the lifting capacity, span, lifting height, power source, or other specials you give us will be more appreciated. It would be better if we had drawings.4. What are the MOQ and payment terms?Our MOQ is just one set, and we accept T/T and L/C at sight, with other terms open for negotiation.5. How do you guarantee the quality?Before shipment, we will perform a series of inspections and tests and provide a detailed tracking report. You can also test through the domestic testing company agent or personally send a delegation to track the testing process; it is okay.6. How can we install the crane? Our senior engineer can be on your side to provide the installation guide service and training.7. Can you provide the serious lifting tools? Sure, we can provide any lifting tools you require, such as lifting sling belts, clamps, grab buckets, Spreader beams, magnets, or other specials!
