TEREX DIGGER DERRICK

ELECTRICAL SYSTEM:STARTER ASSEMBLY

Terex South Dakota, Inc. (Terex) is recalling certain 2018-2019 C4045, C4047, C5050, and C7066 Digger Derrick vehicles. Due to an engine computer program error, if the hood switch fails or opens, the remote engine start/stop function becomes disabled.

Risk: A disabled remote engine start/stop prevents the digger derrick operator from shutting the engine off during hydraulic issues on the digger, increasing the risk of injury.

STRUCTURE

Terex South Dakota, Inc. (Terex) is recalling certain 2017-2018 Terex Digger Derrick vehicles. The guide bar that attaches the pole guide arms to the pole guide tilt bracket may have insufficient welds, possibly resulting in the guide arm falling while in use.

Risk: If the pole guide arm falls, it may strike any nearby personnel, increasing the risk of injury.

ELECTRICAL SYSTEM

Terex South Dakota (TSD) is recalling certain 2012-2017 Digger Derricks and Aerial Devices, models C4000, C5000, C6000, C7000, General, HR, OM, RM,RMX, SC, SCM, TC, TCX, TL, TM, and XT, built on Freightliner chassis with SmartPlex engine controls. The vehicles have a switch to monitor whether the hood is open or not. If the switch thinks that the hood is open, the vehicle software may disable the Aerial or Digger Derrick remote engine control functions.

Risk: If the hood switch prevents the remote engine controls from shutting the vehicle engine down in the event of a hydraulic issue on the Aerial or Digger Derrick, it may increase the risk of an injury.

ELECTRICAL SYSTEM

Terex South Dakota (TSD) is recalling certain 2007-2016 vehicles equipped with Terex C4000, FC, HR, HRX, SCM, TC, TCX, TL, TPL, and XT aerial devices and digger derricks used for utility line work. In the event of a short circuit of a tool plugged into the onboard electrical socket, the GFPE breaker may not trip at the proper current before the user receives a shock.

Risk: Without proper protection against electrical shock, the user has a greater risk of injury.

EQUIPMENT

Terex South Dakota, Inc. (Terex) is recalling certain model year 2014-2015 Aerial Devices and General Digger Derricks manufactured March 28, 2014, to March 1, 2015. In the affected vehicles, the fasteners that attach the turntable bearing to the carrier and the aerial or the digger derrick may fail.

Risk: If the attaching bolts fail, the boom may fall, increasing the risk of injury to the operator or those nearby.

STRUCTURE:FRAME AND MEMBERS

Terex South Dakota, Inc. (Terex) is recalling certain model year 2013-2015 Aerial Devices and Digger Derrick trucks manufactured from June 3, 2013, through November 13, 2014. Due to an issue in assembly, the vertical cylinders and, by extension, the outriggers may drift when loaded.

Risk: Outrigger drifting could result in the platform falling and seriously injuring platform occupants or bystanders.

EQUIPMENT

Terex South Dakota, Inc. (Terex) is recalling certain model year 1999-2012 XL4000 Digger Derrick utility trucks. The shims and spacers used to adjust the length of the hydraulic cylinder may give, causing the rod eye and threads to fatigue while lifting loads.

Risk: The hydraulic cylinder may separate from the digger derick arm, allowing it to collapse without warning, increasing the risk of injury to the operator or those nearby.

EQUIPMENT

Terex is recalling certain model year 2012-2013 Aerial Devices and Digger Derricks manufactured September 2012 through February 2013. The lock valve cavity in the outrigger cylinder may be machined incorrectly and the seals may be damaged.

Risk: Damaged seals may allow the outrigger to drift. If the outrigger cylinder drifts, stability may be affected and the unit may overturn, increasing the risk of injury.
