ii DeckHand Portable Floor Scale

1.0 Introduction

The DeckHand™ Portable Floor Scales are fully electronic, NTEP-certified floor scales allowing one-person
portability on large rubber wheels. Available in painted steel or stainless steel construction, these rugged scales
come in 500 lb, 1000 lb, and 2000 lb capacity.

The heavy diamond-tread platform is 30-1/2 in x 24-1/4 in (0.77 m x 0.62 m) with an overall base height of only
4 1/2 in (0.11 m). The addition of an optional low-angle ramp allows one person to easily roll on a barrel or wheel
on a hand truck. The free-floating ramp pivots back over the deck and rests on the mast for compact storage or
balanced portability.

Figure 1-1. Optional Pivoting Ramp and Indicator

An efficient off-center arrangement of two high-capacity, single-point load cells yields Legal for Trade accuracy.
Electronic components are double-protected from rough use. A RoughDeck™ stainless steel NEMA 4X junction
box is further protected by mounting within the m ast. The optional indicator mounts on a s wivel bracket high
enough on the 59 in (1.50 m) mast to clear the tallest loads.

In addition to ramps, available options include stainless steel load cell guards (clamshell) and indicator brackets for
any Rice Lake IQ series indicator. Other indicators can be readily mast-mounted with slight modifications.

Authorized distributors and their employ ees can view or download this manual from the Rice Lake

Grade Level Requirements

The bubble level built into the platform should indicate
a level condition in use. On uneven floors, place
temporary shims under feet not contacting the floor.

injury.

Indicates a potentially hazardous situation that, if not avoided could result in serious injury or
death, and includes hazards that are exposed when guards are removed.

Indicates a potentially hazardous situation that, if not avoided may result in minor or moderate
injury.

Indicates information about procedures that, if not observed, could result in damage to

General Safety

Do not operate or work on this equipment unless you have read and understand the
instructions and warnings in this manual. Contact any Rice Lake Weighing Systems dealer
for replacement manuals. Proper care is your responsibility.

Before attempting to operate this unit, make sure every individual who operates or works with this unit has
read and understands the following safety information.

Failure to heed may result in serious injury of death.
DO NOT allow minors (children) or inexperienced persons to operate this unit.
DO NOT operate without all shields and guards in place.
DO NOT jump on the scale.
DO NOT use for purposes other then weight taking.
DO NOT place fingers into slots or possible pinch points.
DO NOT use any load bearing component that is worn beyond 5% of the original dimension.
DO NOT use this product if any of the components are cracked.
DO NOT exceed the rated load limit of the unit.
DO NOT make alterations or modifications to the unit.
DO NOT remove or obscure warning labels.
DO NOT use near water.
Before opening the unit, ensure the power cord is disconnected from the outlet.
Keep hands, feet and loose clothing away from moving parts.

1.2 Operating Requirements

Electrical Grounding

Rolling or wheeling loads onto the scale can build up large static charges that may damage the attached indicator
unless it is properly grounded to prevent ESD. This is especially true in dry environments where charges drain off
slowly, or if wheeling on materials which already contain a static charge, like rolls of paper or plastic film material
that have been recently spooled.

To prevent ESD damage, the indicator requires a three-prong 120 VAC outlet plug with continuous earth
ground. Do not attempt to use the scale with two-prong 120 VAC power without a ground.

2.0 Installation

Shoulder Bolts,
Pivot Washers

Overview

Assembly of the scale consists of the following steps:

1. Unpacking

2. Assembling mast onto scale base

3. Installing optional pivoting ramp

4. Mounting and wiring the indicator

5. Configuring the indicator

6. Calibrating the unit with test weights

2.1 Unpacking

The standard scale, with no added options, is shipped with load cells and indicator cable pre-wired into the junction
box on the mast. The indicator can be mounted and wired after the mast is in place.

Remove all packing material and inspect base and mast components for visible damage caused during shipment.

2.2 Installing Optional Pivoting Ramp

If the optional ramp is to be installed, set it flat on the floor in position in front of the scale so the holes in the base
align with the holes in the ramp pivot arms.

Figure 2-1. Pivoting Ramp

Insert a shoulder bolt with a single washer through an arm pivot hole. Slide three plastic pivot washers onto the bolt
for clearance between the arm and the base. See Figure 3-5. After the bolt engages the threads in the base, tighten
the shoulder bolt snugly. Repeat for the other side.
