Combined T/ K Boom crane

TSL combined telescopic/knuckle boom series is a fully hydraulic Elbow Knuckle/Telescopic boom Marine Crane on slewing bearings, from 30 to 800 TM. The kind of crane was developed from knuckle boom crane, the biggest change is the telescopic boom instead of the knuckle boom, so that they have two functions of knuckle and telescopic boom. Customers can benefit from space saving and reliable cranes, that’s the successful combination of economic and performance orientated criteria.
Knuckle/telescopic boom crane is composed of boom system, slewing column, slewing bearing, pedestal, hoisting winch, slewing drive, luffing cylinder, knuckle cylinder, telescopic cylinder and power pack.
★ Slewing drive:purchasing from some 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 or10,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 which would be mounted on a fabricated bracket in the slewing column, the power are also provided
     by diesel engine or hydraulic power shear with others
