is powered by a 20 HP 380 volt 3-phase
electric motor and came with a 30-gallon
reservoir, four manual operated Enerpac
control valves, a master control valve, five
pressure relief valves, four pressure gauges,
loop filtration circuit, four pressure port
outlets with counterbalance valves and
quick couplers and four return ports with
quick couplers.
The jacks supplied by Hydra-Slide were
standard Power Team RD556 cylinders.

being one of the strongest and toughest
timbers available. It is

Moving a
super yacht
Atlas Enterprises
recently moved
the heaviest object
employees have
transported since the
company was founded
as Ron Holland
Housemoving in the early 1970s.
The super yacht, a 215-foot and 480-ton
structure, is equipped with a swimming
pool on deck that doubles as a helicopter
pad when the pool cover closes over the
top.
“It’s not the largest thing I have ever
driven,” said Chris Holland, president of
Atlas Enterprises, “but it is certainly the
most expensive.”
HMR Supplies, a sister company, has
supplied equipment for the yacht builder’s
use numerous times. However, the
company wanted the skilled engineering
and professional experience of the Atlas
team to get the super yacht, which is long
enough and heavy enough to be classified
as an ocean liner, to the body of water it
uses for its sea trials. Due to the size of
the super yacht, there was very little room
in the fabrication facility for placement of
trailers under the yacht.
The move began with two full days of
preparation that included completing
the bolster and cradle system that had
been engineered and fabricated by HMR
Supplies. Once the yacht was securely
nestled into the bolster system, the dollies
that ultimately carried the super yacht
onto the barge were put into position.
The move ended after an eight-hour
session that required the removal of the
doorway header within the fabrication
facility due to only three inches of
clearance for height and navigation of a
90-degree turn in tight quarters.
“It was highly satisfying to see it all
work smoothly,” says Holland. “Several
times the margin of error was as low as
two inches. I’m incredibly proud of our
team.”
Atlas’ two partner companies – CR
Holland Crane Service and HMR
Supplies – assisted with project logistics
that included 12 Coaster Holland Dollies,
4 Powered Holland Dollies and two
power units. No push or pull truck was
used to move the yacht. Holland said two
power dollies placed in front propelled
the super yacht out of the fabrication
building and through the city streets. To
reach the launch area, the structure had

to navigate an extremely tight fit between
a building and a fence just before making
the 90-degree turn.
Holland said that the turn would
not have been possible without all
four Powered Holland Dollies that
are hydrostatically driven and run by
remote control. Two of those dollies
moved the back end of the super
yacht independently of the front end
throughout the turn.
Once at the water’s edge, the super yacht
was launched from a barge that carried
it into deeper water where the barge was
then sunk. As the yacht was moved slowly
onto the barge, water was pumped into
the ballast tanks on the barge to safely
accommodate the weight of the yacht.
The bolsters, which were supported and
lashed down before dollies were removed,
remained on the barge until after the
yacht was launched for its sea trials.
After a trek that often involved steering
with only inches of clearance and a
complex 90-degree turn, Chris Holland,
president of HMR Supplies, moves a new
215-foot, 480-ton super yacht out of the
fabrication facility to the barge for its
initial launch and sea trials.
