Product Description Product DescriptionFoldable Boom Marine Deck Crane--- Telescopic knuckle boom marine craneOEM & ODMCertificate: ABS, BV, CCS, DNV, LR, NK, RS, ISO9001, CESlewing angle range: 0-400°The Foldable Boom Marine Deck Crane is a type of marine deck crane featuring a telescopic and folding boom design, also known as a telescopic-knuckle boom marine deck crane. Powered by an electric motor that drives a hydraulic pump, the Foldable Boom Marine Deck Crane supplies power to hydraulic cylinders, enabling functions such as the telescoping, luffing, and slewing of the crane boom. When not in use, the boom can be fully folded, occupying only 1/3 of the deck space required by traditional straight-boom cranes, making it an extremely convenient deck crane solution.Main components:1. Boom system: comprising telescopic and folding boom sections made of high-strength materials to withstand the loads involved in lifting.2. Hydraulic system: It contains hydraulic pumps, hydraulic cylinders, hydraulic valves and other components, which are responsible for providing power and controlling the movement of the boom.3. Electric drive system: usually consists of an electric motor, controller, etc., which provides power to the hydraulic system.4. Lifting mechanism: hooks/spreaders, wire ropes, etc., for attaching and lifting heavy loads.5. Slewing mechanism: It enables the boom to rotate horizontally, increasing the flexibility of work. 6. Control system: including operating handle, control panel, etc., for the operator to control the crane's various actions and functions.7. Pedestal: Fixed on the deck, etc., to increase the stability and carrying capacity of the crane.Features:Telescopic folding cranes are compact and can be easily installed on all types of vessels; the contraction and folding of the lifting arm makes them light and flexible, taking up little space, and with a large lifting capacity and a wide range of working radius.ApplicationsCollapsible telescopic boom cranes are particularly suitable for use on ships, oil rigs, and other offshore platforms where space is limited and heavy lifting is required.Design Drawing Product ParametersMain technical parameters30KN×17m Hydraulic folding boom telescopic slewing craneSafe working load30kNDrive systemHydrauliclifting height20mEnvironmental temperature-10oC-45oClifting speed10M/minLuffing time110SRotation speed0..6r/minLuffing time60sRotation angle359°(Incomplete rotation)Motor specificationY160L-4-HWorking radius2.5~17mMotor power20KWCable50mMotor duty systemS6-40%Allowable tilt angleHeel≤5°Motor power source380V /5HZ/3PTrim≤2°Protection classIP56Protection level of electric control boxIP23Insulation classFElectric control box controls voltage220V/50HZ/1P Note: 1.

According to the crane's boom type can be divided into: straight jib crane, folding jib crane, telescopic crane, and telescopic folding jib crane.2. Divided according to operational areas (Classification Society Code Naming)Ordinary cranes(ship crane): operate in ports or sheltered waters where there is no significant movement of the ship under wave action.Offshore cranes: Cranes used on ships or platforms that operate in open waters offshore. The sea conditions in these waters can cause significant movement of the vessel or platform.Heavy cranes: SWL >160T3. Divided according to service categories: service cranes, grain and cargo lifting cranes, fishing cranes, platform cranes, grab cranes, and so on.We can design and produce cranes according to the operational scenarios and specific requirements, accept non-standard customization, and customers can also choose the required functions according to their requirements.Mini ship craneOffshore CraneHeavy CraneWorking PrincipleFolding knuckle boom marine deck crane provides power through the electric motor, drives the hydraulic pump to generate high-pressure oil, and then pushes the hydraulic cylinder to realize the extension, contraction and folding of the boom, to complete the lifting work of heavy objects.ImportantIt 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 accurately manufacture a marine crane to your specifications. * 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?CertificationCooperationWe start from 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? Yes, we operate a factory 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 detailed requirements! So if you give us more information about the lift capacity, span, lift height, power source, and other specs, we will give you a very quick quote! 3. What information should I provide when inquiring? The more information you provide, the more accurate the solution we can prepare for you! The information, such as the lifting capacity, span, lifting height, power source, or other special information 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 do a series of inspections and tests, and have a detailed tracking report. You can also go through the domestic testing company agent testing, or you can personally send a delegation to track the testing process; it is ok.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 such as lifting sling belt, lifting clamp, grab bucket, Spreader beams, magnet, or other specials as your requirement!
