I've only seen one rendering, and it's from an aerial view.  From that angle it's hard to tell what impact it will make in height and hard to tell the exterior materials. It's one that should be brick, but whatever is used will determine if this is attractive or not. Keeping fingers crossed.

North tower crane nearing completion.

Looking north from Lafayette, 1/2 block east of 6th Ave. South:

Sixth South, Mar 18, 2020, 3.jpg

When assembling the crane on 3/18 they did not add the small metal extension at the top and the cables attached to it that lend extra support to the boom (my terms may not be correct).  Is that extra support required on every crane or do some not need it?

How do flat-tops differ from other tower cranes?

The main difference is that flat-tops, also called topless cranes, do not have an A-frame or cat-head structure above the tower, as well as pendant lines that connect the top of the A-frame to the jib and counterjib. The absence of these items makes transporting, assembly and erection easier and quicker. Additionally, when a construction project requires multiple cranes, the jib of one crane requires less height clearance to pass under the jib of its neighbor.

Traditional hammerhead tower cranes utilize the A-frame structure for additional strength in lifting cargo. With no A-frame present, flat-top cranes lift comparatively less. In recent times, however, flat-tops with lifting capacities of 32 to 50 tons have entered the market. Conventional flat-tops typically lift 8 to 10 tons, so newer models with higher capacities have become a welcome response to market demands.
