Insulated work platforms increase utilization of cranes and digger derricks

Diversified Products’ IWP-765kV insulated work platform enhances worker productivity and increase job functions performed with hydraulic telescoping cranes and digger derricks.

Waco, Texas, March 5, 2010—Responding to requests for work platforms capable of providing electrical insulation at voltages up to 765 kV, Diversified Products introduces the IWP-765kV insulated work platform. Designed to enhance worker productivity and increase job functions performed with hydraulic telescoping cranes and digger derricks, the platform permits bare-hand work and de-energized line construction, and reduces lineman fatigue by eliminating the need to climb towers.

Featuring a tried-and-proven design, the IWP-765kV provides electrical insulation to personnel working on live transmission lines and equipment at voltages up to 765 kV. The insulated jib consists of a main structural fiberglass member, which is filament wound with computer-controlled, continuous-roving epoxy/anhydride resin. It’s also sealed with bulkhead covers to minimize maintenance and protect from contaminants that may reduce insulation properties. A desiccant canister detects any moisture within the sealed jib and is visible from the ground when the jib is in a stowed or un-stowed position. Furthermore, a high-performance, sharp-edge corona ring reduces current leakage and is rated up to 765 kV.

The IWP-765kV features a radio control system that provides flexible, yet precise operation. The control system incorporates fully proportional controls. These allow simultaneous operation of the telescope, boom and rotation functions and enable the operator to better position the platform to suit virtually any job. A speed selector provides a choice of “fast” or “slow” operation to match the application, while programmable controls allow for precise and smooth operation while ramping up and down. For enhanced serviceability, LED displays are located within the control box, providing self-diagnostic information.

Every unit comes standard with a two-man, steel constructed basket, which can be easily installed and removed by two linemen. It features a 600-pound capacity, 36-inch by 72-inch platform, with the controls located on the curbside near the top rail. Serviceable, self-lubricating bushings are located on all pivots, and a ground access adds convenience for entry and loading. The basket is gravity hung with a closed-loop brake cylinder to dampen movement and lock it into position. Custom baskets are also available to suit specific requests.

Minimal set-up time is required to install the IWP-765kV on most hydraulic telescoping cranes. Crane specifications are reviewed prior to installation, and field or factory installation is provided standard. Other standard features include test bands and shield, boom-tip bonding straps, cable reel, lanyard attachment(s), current leakage monitor and battery charger. The jib and controls meet or exceed ANSI A92.2, ASME B30.23, CSA Z150 and CSA 225 standards.
