DESCRIPTION

Rieker's mechanical boom angle indicators are all-weather and will not rust, freeze, or otherwise "hang up" like oldfashioned metal pendulum styles. Like all of our instruments, each indicator is properly dampened for smooth reliable readings.

The housing is designed for easy mounting with two screws, allowing for quick and efficient retrofitting in the field.

With bright, long-lasting LEDs, the backlit models are highly visible for increased safety - especially at night!

APPLICATIONS

The 4120 is recommended for use on any boom where quick accurate inclination measurements must be taken under difficult conditions and harsh environments.

The 4120 meets OSHA Standards for Cranes and derricks and with installation makes the equipment compliant to the standard.

Typical applications include aerial lifts, truck-mounted boom cranes, any fire truck with a mounted boom or ladder, telescoping off-road variable reach fork lifts, cranes and derricks.

5012P Gradiometer

Mechanical “Ball-in-Tube” Grade (Slope) Indicator

Page 1 of 1

Features

Part Number Shown: 5012P “Gradiometer”

Accurate, Rugged Inclinometer for Measuring Slope or Grade

2 Scales: Inch per Ft-Rise and % Grade

Weatherproof - will not rust or hang up

UV Resistant

Extremely shock and vibration resistant

Description

Easily installed – quick retrofitting

Quick and accurate visual reference

Operational from -50° F to +180° F

A Gradiometer is any of various surveying instruments for measuring angles of elevation, slope, or incline, as of an embankment or roadway. Also called clinometer or inclinometer, the 5012P provides accurate measurement of slope in Percent Grade and Inch Per Foot Rise. Rieker manufacturers these manual type gradiometers (or inclinometers) using precise glass tube and ball construction. All our tubes are filled with a special dampening fluid that controls the movement of the ball. The fluid combined with large, clear number and degree markings make it easy to get quick, accurate readings under a wide variety of severe environmental conditions.

Applications

Plows, graders, excavators, trenchers, and pavers are only a few examples of the types of applications well suited for gradiometers.
