Jekko’s new SPX650

Italy – Jekko has welcomed the latest addition to its range, SPX650, the 5 ton mini crane with a maximum reachable height of 23.5 m (with jib) which embodies many state-of-the-art innovations and promises to become a flagship model of the Treviso-based company.

Thanks to the experience gained over the last two years with SPX532 and SPX1280, Jekko could concentrate in one machine the best features and the most advanced technical solutions already successfully applied in the two best-selling models.

SPX650 boasts cutting edge stabilization and hydraulic systems, new hydraulic jib and runner jib (with plug and play attachment), a lithium battery power supply and a handy radio remote control. Besides that, the crane features other important functionalities such as the possibility of working either with hook or winch, the extendable tracks, the availability of pick and carry mode and the telemetry system J-Connect. And all this without neglecting the design and quality materials, with a close attention to detail.

“The idea behind new SPX650 comes from the market needs,” said Alberto Franceschini, Jekko export sales manager. “Our customers were looking for medium size mini crane, with a length of the boom over 20 m and a very good lifting capacity. Operators were asking for a crane that can work both indoor and outdoor, suitable in many job sites: glazing, curtain walls installation, steel erection, industrial maintenance. So we analyzed both what the competition was offering and our own range, and the result is SPX650”.

A sophisticated hydraulic system: SPX650 can count on a 100% electronically-operated supply system with PVG 16 proportional bank valves by Danfoss, the same of SPX532 and SPX1280, which allows smooth and accurate crane movements and the possibility of working simultaneously with four functions.

“The heart of the hydraulic system is a load sensing piston pump, driven by our own power management control: this can guarantee the operator all the crane’s power, speed and control he needs, with the minimum consumption required,” said Marco Zava, Jekko R&D director.

New stabilization system for endless operating configurations: From the bigger SPX1280, SPX650 inherits also the new stabilization system, entirely and directly controlled by radio remote control. The crane is equipped with X-pattern outriggers with double extension (by cylinder and chains) to reduce the minimum stability area (2.9 x 2.9 m; 4.5 x 4.5 m the maximum area). Stabilizers feature also hydraulic rotation from 0° to 72° and a double regulation position of their height, for the maximum flexibility while operating in confined areas. The system considers several factors in order to determine the possible working conditions: depending on the opening angle and extension of the stabilizers, the software can define in real time the maximum safe working load in a specific point, with 5 total stability levels.

Greener and more efficient power supply by lithium batteries: SPX650 is equipped with a custom designed 48 V lithium battery pack with a capacity of 400 Ah, which powers a 16 kW three-phase electrical engine. Thanks to the 220 V single-phase charger on board the machine it is possible to work under charge; an external 400 V three-phase charger is also available as option. Lithium battery supply requires no maintenance and batteries can last for the whole crane’s life. Moreover, it allows unchanged and constant performance even in case of intense use with heavy loads, not to mention the possibility of operating indoor without any kind of emission.

New 1.2-tons hydraulic jib: The crane features a new 1.2 tons hydraulic jib with 3 extensions (1 hydraulic, 2 by chain) to achieve a maximum reachable height of 23.5 metres and a new 2-tons runner jib, ideal in glass installation. The jib can be stored in three ways, as in SPX532: at rest on the column, on the ground or under the main boom. Rest position under the main boom means significant reduction in jib installation and disassembly times. Last but not least, the jib can work with a negative angle up to 15°, for a greater application versatility.

Practical radio remote control: Everything is in the operator’s hands with the practical radio remote control, which is the same of SPX532 and SPX1280. It features LCD display and a software developed internally by Jekko; using selectors that link to intuitive screens it allows to directly activate or deactivate all crane functions: boom and winch speed, crane’s configuration selection (pick & carry, crane, outrigger ascent and descent, tracks) and manipulator.
