Explore heavy haul

This is a 50/50 company between Select Plant Hire (Laing O’Rourke) and W S Transportation (owned by William Stobart son) I understand they have purchased three new Mercedes Titan 250ton 8 wheel tractor units to do the work for Weldex Crawler cranes,this work had been done for many years by Heanor Haulage,however the manager at Heanor left and took several of the drivers( £4 per hour more )with him to Explore.I wonder how they can make the work pay as the rigs cost £400k .(£8000 per month hp)
Heanor was a good company with many years of practical experience but they are old school and all there fleet was sold by Malcolm Harrison Auctions.
I wonder how long William Stobart will keep supporting W.S (3.9m loan)seeing as W S turned over 18m and made a pre tax profit of 72k on there last accounts.
