意大利微型起重机制造商Jekko推出了SPX650，这是一种电动微型起重机，该公司表示，该机器填补了其SPX532和SPX1280型号之间的空白。
SPX650的最大起重能力为5吨。五节主伸缩臂的最大工作高度为16.5 m，最大延伸范围为14 m。动臂在2.9 x 2.9 m的最小稳定区域内可连续旋转360度，可用于吊钩模式或绞车模式。
借助液压悬臂，最大伸展范围为19.8米，可到达高度为23.5 m。液压臂架最多可提供三个扩展（一个液压，两个按链条），最大容量为1.2吨。可实现负15°的副臂角度，以实现更大的多功能性。也可以使用较短的2吨副臂（runner jib）这种副臂特别适合玻璃安装等应用。
副臂可以用三种不同的方式存储：静止在立柱上；在地上;或在主臂下Jekko借助即插即用设计，将其存放在主臂下，安装和拆卸时间仅为3分钟。
Jekko说，SPX650专为室内和室外使用而设计，适用于各种应用。它的轨道可以向外延伸，从而使SPX650能够为轻巧的货物提供拾放功能。
起重机的操作是通过遥控器进行的，并且提供Jekko的J-Connect远程监控和辅助技术的支持。
该起重机具有一个三相16 kW发动机，由48伏容量为400 Ah的锂离子电池供电。使用大功率400伏特充电器，电池可以在三个小时内充满电。使用起重机上的常规充电器需要9个小时，起重机还可以在充电时使用。
杰科说，SPX650还将在2021年配备柴油发动机和三相电动机。
起重机的液压系统使用的是与丹麦跨国公司Danfoss相同的PVG 16比例倾斜阀，与SPX532和SPX1280上的阀相同。液压系统具有一个负载感应活塞泵，该泵由Jekko自己的动力管理控制器驱动。该公司表示，这可以以所需的最低功耗提供操作员所需的所有动力、速度和控制力。
Jekko期望新起重机在下一年中占其总营业额的15％至20％。

Versatile mini crane
By Christian Shelton
Italian mini crane manufacturer Jekko has launched the SPX650, a medium-sized electric mini crane, which the company says bridges the gap between its SPX532 and SPX1280 models. The crane utilises proven technology from both these cranes, as well as introducing new features.
The SPX650 has a maximum lifting capacity of five tonnes. The five-section main telescopic boom has a maximum working height of 16.5 m and a maximum outreach of 14 m. The boom has 360 degrees continuous rotation within a minimum stabilisation area of 2.9 x 2.9 m and can be used in either hook mode or winch mode.
With its hydraulic jib, maximum outreach is 19.8 metres and it has a reachable height of 23.5 m. The hydraulic jib offers up to three extensions (one hydraulic, two by chain) and has a maximum capacity of 1.2 tonnes. A negative jib angle of 15° is possible for greater appliCATion versatility. A shorter, two-tonne runner jib is also available. This runner jib is particularly suited to appliCATions such as glazing installation, says Jekko.
The jib can be stored in three different ways: at rest on the column; on the ground; or under the main boom. When stored under the main boom, installation and disassembly times are as little as three minutes, says Jekko, aided by its plug ‘n’ play design.
The SPX650 utilises the SPX1280’s proven X-pattern outrigger system which can extend to provide a stabilisation area of up to 4.5 x 4.5 m. The stabilisers can also be adjusted with up to 72 degrees of swing. Stabilisation software ensures the maximum safe working load for any configuration.
Designed for use both indoors and outdoors, Jekko says the SPX650 is suitable for a wide range of appliCATions. Its tracks can extend outwards enabling the SPX650 to provide pick and carry functionality for lighter loads.
Crane operation is via the same in-house designed remote control as found on the SPX532 and SPX1280 and is backed by Jekko’s J-Connect remote monitoring and assistance technology.
The crane has a three-phase 16 kW engine electrical which is powered by a 48 volt lithium-ion battery with a capacity of 400 Ah. Using a high power 400 volt charger the battery can be fully charged in three hours. Using a regular 220 volt domestic power source this takes nine hours, via the onboard charger, although the crane can be used whilst being charged.
In 2021 the SPX650 will also be available with a diesel engine paired with three-phase electric motor, Jekko says.
The crane’s hydraulics use the same PVG 16 proportional bank valves from Danish multinational Danfoss as found on the SPX532 and SPX1280. The hydraulic system has a load sensing piston pump which is driven by Jekko’s own power management control. The company says this offers all the power, speed, and control the operator needs with the minimum power consumption required.
“The idea behind new SPX650 comes from the market needs,” comments Alberto Franceschini, Jekko export sales manager. “Our customers were looking for medium-size mini crane… that can work both indoor and outdoor and is suitable for many different job sites. We analysed both what the competition was offering and our own range, and the result is SPX650”.
Jekko expects the new crane to account for between 15 to 20 percent of its total sales turnover over the following year.
