TSL knuckle series is a fully hydraulic Knuckle boom Marine Crane on slewing bearings, from 30 to 800 TM. Thanks to the double boom articulation configuration, the crane occupies a very narrow space in stored position. They make full use of their strength and flexibility when loading and unloading equipment, material, tools and fishing equipment, including handling containers. Their compact construction means that they can easily be accommodated on small ships, yachts and docks where space is limited.
 
TSL Knuckle boom crane is composed of boom structure, slewing column, slewing bearing, pedestal, hoisting winch, slewing drive, luffing cylinder, knuckle cylinder and power pack, etc.
 
★ Slewing drive：purchasing from famous brand product suit for marine environment or according to customer’s
      request
★ 360° Continuous rotation
★ The knuckle boom can be folded from 0 to 120 degree relative to the main boom; so that it can get a lesser
     outreach distance and lesser space in packing and working position
★ Main boom luffing: up to 80º
★ Hoisting winch: Compact design with planetary gearbox & hyd motor, easy to install and maintenance
★ Emergency release: manual operate to low down the load stably when crane lost power
★ Cut off switch: limit the hook upwards and downwards position to avoid over hoist & lost wire
★ Generally, Winding layer of wire rope is less than 3 layers on the drum, if need more layers, the LEBUS type
     groove will be applied
★ Man riding winch/crane: to make sure safety and reliability, 2 mechanical brake systems are equipped on the
     type of hoisting winch, safety coefficient of the wire rope is more than 8 or 10, the structure strength coefficient
     is over 4
★ The power pack is usually installed inside the crane, the electric motor would be flexibly coupled to hydraulic
     pump whichwould be mounted on a fabricated bracket in the slewing column, the power are also provided
     by diesel engine or hydraulic power shear with others
