The RoughDeck
®
Floor Scales are fully electronic, low profile load receivers. The RoughDeck is available in sizes
from 30 in x 30 in (.76 m x .76 m) to 96 in x 120 in (2.44 m x 3.05 m), and capacities from 2K- to 30K-lbs
(1000–15000 Kg). The RoughDeck comes in several versions, including the stainless steel HE model designed for
harsh washdown environments.
All models use four corner-mounted, FM-approved load cells, with the cells recessed into the frame channels for
protection. A signal-trim summing board for any necessary corner corrections is enclosed in a junction box
mounted on a slide-out tray for easy access. The stainless steel models use a stainless steel NEMA Type 4X
junction box. Mild steel models feature the same board housed in a standard plastic junction box. All models come
pre-trimmed, and corner corrections should not be necessary.
Load cell cables are enclosed in conduit through the main channels, and held down with replaceable cable ties near
each corner, eliminating the possibility of cable damage in portable applications. Also useful for portable
applications are threaded corner holes in the deck for removable eye bolts to allow lifting the scale from above with
chains. Because of the possibility of foot and load cell damage from forklift tines, the scale should always be lifted
from above with chains through the eye bolts.
The adjustable feet are used to allow leveling the scale to make up for minor floor irregularities. For permanent
installations, two of the four feet can be held in place on the floor with optional floor mounting plates to guard
against deck movement.
Other available options include custom frames for pit installations, and access ramps for all sizes and models of the
RoughDeck. Decks designed for use in pits can be ordered with holes drilled in the deck directly above each foot
for adjusting foot height with a screwdriver from above. See Section 4.4 on page 15 for replacement part and
optional equipment part numbers.
