The job crane has a standard height of 3m under upper lifting hook of 3m. This height can be adjusted to be higher or lower thus modifying overall instrument height. For further customization or for a height under the upper lifting hook higher than 4m, contact the company. This articulated pillar jib crane is ideal for indoor use. There is a 270° rotation for arm 1 and 300° rotation for arm 2. This jib crane type cannot be motorized at all. Theoretical deflection for this machine would fall under the nominal load which is approximately 1/250th of the span + height. However, it cannot exceed 1/100th of the span in itself. The machines maximum hoisting speed is 8m/min. The machine comes with lockable main switch and it has the rotation slowing device mechanism. It can be used for hoisting power supply cable and it offers 3 layer protection system for extra safety.
