TEREX AERIAL DEVICES

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.

STRUCTURE

Terex South Dakota, Inc. (Terex) is recalling certain model year 2007-2013 TLM37, TLM40, TLM41, and TLM50 aerial devices manufactured March 29, 2007, to January 31, 2013. The aerial devices have the pedestal attached to the lift turrets that may crack due to missing reinforcements.

Risk: Cracks, if not repaired, may result in the failure of the aerial pedestal, increasing the risk of injury to the operator or those nearby.

EQUIPMENT

Terex South Dakota, Inc. (Terex) is recalling certain 2008-2015 TLM37, TLM37P, TLM39, TLM41, TLM50, TLM55, and TLLM60 aerial devices manufactured June 18, 2008, to September 28, 2015. On the affected devices, both the boom tip leveling cylinder and the master cylinder at the elbow may make contact with the structural components, potentially damaging the boom tip leveling cylinder rod eye and the master cylinder rod eye.

Risk: Repeated contact may result in the rod eyes cracking. This cracking can lead to the failure of the boom tip leveling cylinder rod eye and the platform tilting unexpectedly which could cause the occupants to fall from the aerial platform, increasing their risk of injury.

STRUCTURE

Terex South Dakota (Terex) is recalling certain model year 2011-2016 HR, HRX, TC, TCX, and SML aerial devices. The affected aerial devices may have inadequate welds at the boom tip leveling sprockets. A failure of these welds may result in the platform tilting unexpectedly.

Risk: If the platform tilts unexpectedly, the user may fall, increasing their risk of injury.

STRUCTURE

Terex South Dakota, Inc. (Terex) is recalling certain model year 2011-2015 SCM48, SCM50, and SCM55 aerial devices manufactured August 24, 2011, to November 5, 2015. The affected vehicles have a leveling cylinder linkage that can be forced past its intended stop position, causing damage to, and failure of, the leveling system.

Risk: If the leveling system fails, the aerial platform may tilt, increasing the risk of injury to the user or those nearby.

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.

STRUCTURE:FRAME AND MEMBERS

Terex South Dakota, Inc. (Terex) is recalling certain model year 2006-2014 TLM series models manufactured from December 2006 through February 2014 which were installed on Ford F550 vehicles. The affected vehicles may develop a crack in a notch of the vehicle frame.

Risk: A crack in the frame may cause frame failure, resulting in a loss of vehicle control, increasing the risk of a crash.
