Description

RON portable digital scales include the Crane Scale, Dynamometer Load Cell and Overload Detector series.

The low headroom RON 1000 Standard Type Overload Detector is designed to be installed on the dead end or can be used between the hoist and its trolley.

RON 1000 Standard Type is a low headroom, electromechanical Overload Detector, used for overload monitoring. It may be configured to trigger any desired electrical alarm supplied by the customer, including stopping the lift when an unsafe overload condition occurs, for overload detection and prevention.

Overload during lifting: Hoist or crane overload is dangerous and can cause accidents. Overload monitoring is important for prevention of crane overload.

The devices are supplied factory-calibrated and ready for installation. Available in a wide variety of capacities, the RON 1000 can be supplied in capacities ranging from 500 lbs (250 kgs) to 20,000 lbs (10,000 kgs). Each unit is initially adjusted to give the user an overload indication at 105% of rated capacity. Additional detection point is optional.

RON portable digital scales: Crane Scale, Dynamometer and Overload Detector series are factory-tested and supplied with a test certificate, including a fully traceable calibration chart.
