Presented here is the latest release in the series of Grove
precision scale replica models. The 1:50th scale RT540E rough
terrain crane features a host of fine detailing throughout which
demonstrates the high level of engineering and attention to detail
that TWH Collectibles put into each and every release.
The four large outrigger arms extend from the chassis and while
they are a little tight, this helps greatly in ensuring that once
the pads have been lowered, the arms remain perfectly horizontal
with no noticeable droop. The jacks have been constructed with the
screw thread hidden inside which makes the pistons look very
Yellow chevron warning markings and tiny safety labels have also
been added. The rear of the chassis houses the engine compartment
with access steps, metal grab rails and towing loops all visible.
The light housing has been integrated into the frame and a photo
etch grill with a honeycombed style pattern is utilised at the rear
of the engine bay to protect the cooling systems.
The battery compartment can be opened to reveal the moulded
batteries with flexible piping also visible. Side mounted access
steps are found on both sides of the chassis giving easy access to
the operators cab. The exhaust stack is protected with a photo
etched jacket which really does give the model a more realistic and
lifelike appearance and the side engine cover can be opened to
reveal the engine components packed into the engine bay.
The underside of the model reveals even more fine detailing
including the drive train from the transfer casing to the front and
rear axles. Various hydraulic hoses have been added and both axles
feature functional steering allowing a number of posing
possibilities. The moulded rubber tires have a very distinct and
crisply cast tread pattern with yellow wheel hubs and black
The large, angled counterweight fitted to the upper carriage
frame has a photo etched grill on the rear surface with two winches
mounted into the frame. The upper surfaces have a black printed
surface to simulate the anti slip panels found on the real machine,
complete with black painted grab rail.
One of the most striking features on the model is the hydraulic
distribution block which has been fully modeled with silver check
valves and both fixed and flexible hydraulic piping traveling to
the replicated hydraulic winch and slewing motors. All this detail
is hidden behind the removable access panel and this level of
detail and realism is what makes TWH models stand out.
The cab has been very nicely modeled with patterned floor panel,
sliding cab door and all the controls accurately placed. Safety and
operating instructions are printed on the side window with several
grab rails strategically positioned for safe cab access. Even the
fire extinguisher has been added along with a printed safety mesh
screen on the inside window along with highlighted rubber window
seals and both front and roof mounted windscreen wipers all adding
to the realistic appearance.
The four section telescoping boom extends smoothly with nice
detailing of each section, complete with a printed Grove logo. The
boom lift hydraulic is just about stiff enough to hold the boom in
the air with a hole drilled into the cylinder to allow the boom to
be secured in the raised position with a small pin. There are two
identical hooks supplied with the model. One hook is already fitted
to the front winch and reeved through the pulleys on the boom head
while the second hook is supplied separately in the box.
There is also a load sensing device attached by a fine metal
chain which is a nice touch, although on the model reviewed here,
the hook has a tendency to twist due to the way it has been reeved.
The swing out jib is stored on the side of the boom and fits well
in this position. When the pin is removed from the boom head to
extend the boom, the jib becomes very loose and does not pose
correctly once the boom is raised.
The jib can be extended by removing the pin and re-fastening it
once the inner jib section has been fully extended. This is a
highly detailed and very realistic looking replica of a popular
machine, securely packed in a two section polystyrene carton with
printed cardboard box. A booklet is supplied with the model which
details the specifications of the machine along with a colour
leaflet detailing the assembly steps.
