This week we will be reviewing the 12 tonne Jaso J300 tower crane
The configuration for this crane was a 40 meter mast with a 35 meter jib
A nice well maintained Jaso, I was quite impressed with this crane. It drove like no other due to the short jib, usually these cranes are set up with the max 75m of jib, so for it to only have 35m of jib the slew motors had plenty of power, the slew would start immediately and stop immediately, no gliding to a stop, once you stop slewing on the controls the crane stops, at times it was more like operating an excavator than a tower crane. By far the easiest and most users friendly tower crane to operate in have ever come across, even in strong winds of over 70kms the crane was not affected.
The hoist speed on this crane was fantastic, we had it in 4 part to do concrete panels the largest of those 10 tonnes and there was no need to change back to 2 part, plenty of speed even with 4 part.
There was not much deflection on this crane, to be expected given the short jib and tower size
The crane cabin was big and comfy, the aircon worked a treat, tinting all over the windows, it even had cctv on the hoist drums as a safety feature.
The crane cabin chair reclines all the way back, like a chair on a first class flight. You can catch some sleep when its quite, its very comfortable. How good is that!
There was nothing I disliked on the crane so its getting 5 out of 5, perfect crane.
