Product Description 30KN×17M TELESCOPIC KNUCKLE BOOM MARINE CRANEOEM & ODMCertificate: ABS, BV, CCS, DNV, LR, NK, RS,ISO9001,CESlewing angle range: 0-400°Crane (used to refer to smaller tonnage), also known as ship cranes, refers to the maritime environment to perform transport operations of a special crane, mainly used for ship to ship, ship and shore cargo transport, transfer, supply at sea, underwater operation equipment, such as the launch and recovery of important tasks.Telescopic folding jib crane, also known as electro-hydraulic telescopic foldable boom crane, is a kind of lifting equipment which uses electric power to drive the hydraulic system to realize the telescopic and folding action of the jib.PERFORMANCE FEATURES1. Telescopic knuckle boom marine crane has the characteristics of light weight, flexible manoeuvring and easy maintenance.2. Crane action by the lifting, slewing, luffing, folding jib four power systems.3. The four power systems are all-hydraulic, by an electric motor dragging an oil pump to supply power.4. The electric motor is fixedly installed inside the base.5. The oil pump is fixedly installed on the slewing base and connected to the motor through a universal coupling.6. The hoisting winch is installed on the top of the slewing base, driven by the superior performance piston oil motor and driven by the high-strength planetary gearbox to wind the steel rope to complete the lifting of the goods. The steel wire rope is galvanised anti-rotation type.7. The slewing mechanism is installed on the slewing base, driven by the superior performance of the plunger oil motor, through the high strength planetary gear reducer output pinion and slewing bearing of the internal gear ring direct meshing to achieve the tower slewing.8. Luffing, folding and telescopic action by high-performance hydraulic cylinders to achieve the cylinder limit position with a safety buffer function.9. Crane manoeuvres by the superior performance of the multi-way reversing valve to complete. 10. The open-air console is equipped with a manual emergency oil pump for emergency release in case of power failure. 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.STRUCTURAL INTRODUCTION1. The overall structure of this machine is mainly divided into four parts: pedestal, slewing base, boom and open-air manoeuvring platform.2. The pedestal is a cylinder, which should be bolted to the deck base when using the machine.3. Slewing base and fuel tank are combined into one box structure with compact structure and small volume. It is connected to the base through the slewing bearing in the middle.4. The boom is a box-type structure, welded with plates into a gas-tight structure, the inner cavity does not have to be maintained, the boom is three sections of expansion and contraction of a folding arm.5. Open-air manoeuvring platform is welded next to the tower, all crane operations can be completed on the open-air manoeuvring platform.The crane console position {i.e., the left machine (console on the left) or right machine (console on the right)} optionalDESIGN DRAWINGWe 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.MAIN TECHNICAL PARAMETERSHere are the main technical parameters of our client customised hydraulic telescopic knuckle boom marine jib crane:30KN×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: The data in the table is for reference only, we can customise different cranes according to different needs, accept OEM & ODM .SAFETY SYSTEM1. All lifting, slewing and luffing are equipped with automatic protection device, which has nothing to do with the control oil circuit of the main power system, once power or pressure is lost for some reason, all the movements will be stopped automatically to ensure the safety of the crane.2. There is a safety valve installed in the main control valve to implement the overload protection of all actions.3. The winch and slewing mechanism have automatic braking device.4. Torque limiting device is installed.5. The limiting position of luffing, folding and telescoping is done by the mechanical limiting position of the oil cylinder.6. The upper limit of the hook is completed by the mechanical limit of the boom head.7. Emergency stop device is provided on the open-air manoeuvring platform to ensure the safety of man and machine.CLASSIFICATION OF CRANES1, According to the type of boom can be divided into: straight jib crane, folding jib crane, telescopic crane, 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. Mini ship crane Offshore CraneHeavy CraneImportantIt 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.FAQ1.Are you a manufacturer? Yes, we operate a factory staffed with skilled technicians on-site, complemented by our trading company.2.Is your products customized?
