Strong Design from To Presenting the TK550 Telescopic Crawler Crane to Revolutionize Foundation Work KOBELCO is proud to launch the new TK550 telescopic crawler crane, which combines the stability and lift power unique to crawler cranes with the convenience of an automatic boom extender/retractor. The TK550 model offers many advantages, including the flexibility of an adjustable boom that can match any worksite conditions. It also cuts down on bothersome boom setup and transportation time, and the compact design and maneuverability can handle rough terrain with ease. Of course, the crane is...

Newly designed high-strength telescopic boom Excellent stability and lifting capacity Features and performance suited for foundation work Optimal dimensions and mass for superior mobility Wide range of safety features Equipped with Telescopic Boom Featuring High Strength and Rigidity Operability That Only a Telescopic Boom Can Deliver The automatic boom extender/retractor easily adjusts the length of the boom to match working conditions, making the crane ideal for material handling. Boom Length : Boom Features Both Light Weight and High Stability Despite its light weight, the boom features...

PERFORMANCE Attachments for All Types of Foundation Work High Stability Accommodates a Wide Operational Area Delivers a maximum working radius of 27.6m, with a horizontal lifting capacity of 1.45t with a fully-extend boom. The minimum working radius with a fully extended boom is 3.0m. Maximum Working Radius Features a lifting capacity of 10.15t at a 10m working radius for foundation work, ideal for work that requires vibro-hammer or auger attachments. The lifting capacity of 22t x 6m (when the second and third boom sections are fully extended) is well-suited to vibro-hammer operations. Drum...

TRANSPORT Ease of Transport Makes Set-Up More Convenient Designed for Easy Transport. Overall height 3.385m Operating weight (Standard specification) Overall width Overall length : Counterweight In case of axle extension adaptor installed Telescopic Boom Requires No Assembly/Disassembly The automatic extender/retractor saves time and effort, thereby maximizing time spent on the project at hand. There’s no need to allot space to assemble, disassemble, and store the boom. On-site safety is also increased, as there is no potential for an accident during boom assembly/disassembly. Counterweight...

SAFETY & COMFORT Safety and Comfort Give the Operator Peace of Mind. Operational Range Limiter By setting the parameters of boom angle (upper and lower limits), boom top height, and operating radius, the operator can limit the range in which the boom operates. A warning buzzer sounds and the machine stops automatically whenever those limits are approached. This mechanism has proved successful on wheel cranes, and can be used not only to prevent contact, but also to increase efficiency in repetitive tasks. Engine Start-Up Safety Mechanism Prevents Accidental Operation If the engine is...
