1.0 Introduction

Note

CAUTION

WARNING

DANGER

The RoughDeck® Floor Scales are fully electronic, low profile load receivers. The RoughDeck scales are 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-lb
(1000–15000 kg).

All models use four corner-mounted, FM-approved load cells, wi
protection. Also included is a signal-trim summing board enclosed in a stainless steel, NEMA 4X junction box for
any necessary corner corrections. All models come pre-trimmed; corner corrections should not be necessary.

Load cell cables are enclosed in conduit through the main channe
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
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

for adjusting foot height with a screwdriver from above. See Section 4.4 on page 12 for replacement part and
optional equipment part numbers.

1.1 Model Designations

The model identification label is located on the side of the frame next to the slide-out junction box. Include both
model number and serial number when ordering replacement parts.

A duplicate label is affixed inside the junction box opening.

The following model designations are used to describe the different scale versions:

HP (

Rough-n-Ready)— Mild steel, high precision, NTEP-certified as “legal-for-trade” and FM-approved load

cells.

HP-H
HC

— 20K- and 30K-lb capacity HP models.

— Similar to HP models, the HC includes overload stops at each corner of the platform. This model is

approved by Measurement Canada (formerly LMB) and available for use in Canada.
