First lithium-powered knuckle boom crawler crane from Jekko

Jekko has enlarged its offer of fully-electric minicranes with its first knuckle boom crawler crane: JF235CL.

The lithium-ion-battery power supply makes this crane suitable for indoor jobsites, such as on industrial maintenance, being totally emission-free and low noise. On these types of jobsites, the knuckle boom crawler crane JF235 has already been proving useful with its articulated boom being agile, manoeuvrable in every direction and compact. Now that it is also fully-electric it offers greater efficiency and sustainability.

The new model has the same features and lifting performances of the corresponding diesel model: it reaches a height of 25m, a radius of 23m and a lifting capacity of 6.15t with unchanged lifting diagrams. It is available with accessories including a fly jib, searcher hook, manual extensions and man working platform.

JF235CL features a 48V 67kWh lithium-ion-battery pack providing performance and reliability. To ensure the highest level of safety the battery pack is monitored by a BMS (Battery Monitoring System) fully integrated into the machine’s electronics.

The low voltage battery allows to easily perform troubleshooting without the need of dedicated service licence.  The high capacity battery allows the 12kW motor pump to run with an autonomy of 10 working hours (on 35% duty cycle).

Compared to diesel-powered engines, battery-powered cranes are maintenance free, greatly reducing the service activities required on the crane. The Start&Stop system applied on motor pump ensures a further considerable energy saving and lowers hydraulic maintenance needed.

The crane can be recharged with both single phase (230V) or three phase (400V) chargers. The complete recharge 0-100% can be completed in 6 hours 30 min and the crane can continue to operate at full power without stopping even while recharging the battery.
