Hamm H7i Single Drum Compactors

Presented here is the H7i single drum compactor from NZG which has been produced in four different versions. Both padfoot and smooth drum versions are available with fully enclosed cabins or canopies. The H7i compactor is simple to operate, making it ideal for the rental sector with excellent climbing ability coupled to good driving characteristics and high ground clearance making it ideal for earthworks. In standard configuration, the H7i tips the scales at 6.3 ton and is powered by a Kubota V3307-CR-T diesel engine delivering 73hp. Travel is provided by hydrostatic drive motors giving infinitely adjustable speed up to 12.5km/h

All four versions have the usual level of detailing expected from NZG including the replicated driver’s station incorporating a side console with joystick control and central column housing the steering wheel.

The cabin version has tinted windows which reduce the visibility of the internal details but it appears all four versions share the same internal layout. Externally, there are several differences including the orientation of the rear view mirrors.

The H7i P versions have good detailing of the drum surface with an articulating chassis which provides steering while there is also some oscillation built into the 3-point centre pivot assembly. The tread pattern of the rear tyres is also different with the smooth drum versions having a subtle and intricate tread design while the padfoot versions have a tractor style tread pattern with prominent raised areas.

The front frame has a slightly different configuration between padfoot and smooth drum, with the latter having a close mounted scraper bar. The smooth drum is finished in a silver colour and is freely rotating.

The curved rear engine housing offers an excellent view of the area with surface engraving of the cooling grills which are enhanced with black paint. The paint finish is good throughout with authentic placement of the new Wirtgen Group and Hamm markings.
