Crane Load and Radius Indicator System

Clearly shows total weight of load, load radius, and safe lifting capacity — all on a single gauge

The AOI Crane Load and Radius Indicator System is ideal for construction, dockside, and offshore drilling environments, as well as for material replenishment and salvage operations. Designed for use with gantry, pedestal, derrick, barge, and locomotive cranes, this durable system provides reliable, accurate measurements that help ensure safe lifting operations.

The system consists of a Load and Radius Gauge, a radius Sensor, a Load Cell, a hydraulic Radius Hose, and a Radius Sensor Hose.

Features

  • Large 8-1/2-inch, easy-to-read dial
  • Dial available in a wide range of capacities, up to 300,000 pounds
  • For use with gantry (revolver and whirly), pedestal, derrick, barge, and locomotive cranes
  • For construction, dockside, and offshore drilling environments — and for material replenishment and salvage operations
  • Wide range of models. Dials for multipart line arrangements available.
  • For dead-end applications, adaptable to portal, derrick, and pedestal cranes with suspended upper block. Systems can be coupled for multifall crane applications.
  • Available with integral jaw x jaw clevis with safety pins


The AOI Crane Load and Radius Indicator System is available in three models:

  • Series ACR Crane Load and Radius Indicating System — Shows total load, radius-of-load, and rated load values at specified radiuses.
  • Series ACL Crane Load Indicating System —
    Shows total load in pounds, tons, kilograms, tonnes, or decanewtons.
  • Series AR Crane Radius Indicating System —
    Shows radius-of-load and rated loads at specified radiuses.
