1.0 Introduction

DANGER

WARNING

CAUTION

Important

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 mast. The optional indicator mounts on a swivel 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 employees can view or download this manual from the Rice Lake
Weighing Systems distributor site at www.rlws.com.

Introduction 1

Failure to heed may result in serious injury of death.

WARNING

Important

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 up and down 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.
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.

Load Cell Excitation

Rated Excitation: 10 VDC

Maximum Excitation: 15 VDC

mV/V Signal Output: 2 mV/V

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.

Safe Static Overloading Capacity

Maximum: 150% of scale capacity
