Today I review the 6t Liebherr 100 LC tower crane, the crane was set up with the max jib size of 50 meters, max tower height is 44 meters
The first thing I noticed with this crane is its size. Its only a 6t crane but it looks like a 12t. The large size makes the crane extremely stable. The tower doesn't twist no matter how fast you stop slewing. Deflection is minimal for this size of crane and at 50m it can lift a reasonable 1.6t (unlike other brands that claim it can lift a certain amount and fall short the Liebherr can do what it says)
The hoist speed is pretty good. It will beat just about every other crane on hoist speed that's 8t and below
The wind pushes the jib around real easy so you have to keep an eye on the jib if operating by remote, but it has a great slew brake. The slew motors don't decelerate like other tower cranes. With the Liebherr driving is different, you slew, reach desired slew speed (this happens quite quick, it has good slew motors) and just let the crane glide along. To slow down and stop you just back slew, there's no letting it glide to a stop. It takes a little while to get used to but when you do you don't want to operate anything else. Dogman says stop slew, backslew, jib stops completely.... Its that easy.
Just don't forget to apply the slew brake as soon as possible because even with hardly any breeze the jib will move.
No matter how hard you back slew it doesn't faze this crane, the jib wont bend and shake and the tower wont twist.
The remote is something else. Its huge, way bigger than the big Hetronic remotes you get with Potain cranes. The levers make it feel like you are operating a crane not a remote control car. It even has a thumb button on the hoist lever to give micro hoist speed - just like the cabin controls. Some crane operators will whinge about having to carry around a remote the size of a large infant... Bad luck for them!
The only disappointment on this crane was the cabin. It was small, real small. Room for a seat and the controls and that's it. Access to the cabin is via the roof, you pretty much drop into your little seat.
Believe the hype, 4.5 out of 5
The easiest crane to operate ever!
