Technology AssociatesForklifts, industrial trucks, skid steer loaders, bobcats and other similar material-handling machines are often difficult to maneuver and susceptible to a wide range of accidents. Their nature exposes operators and nearby co-workers to falling loads, crushing hazards and lading dock falls. Large loads and high centers of gravity also make these machines prone to tip-over accidents. To mitigate some of these dangers, machines are usually equipped with Roll Over Protective Structures (ROPS), Falling Object Protective Structures (FOPR) and other forms of guarding. Machine speed and braking acceleration is often controlled electronically to reduce the likelihood of a tip-over.

Expertise

At Technology Associates our testing, research and analysis capabilities include:

  • Stability analysis
  • Component failure
  • Brake testing
  • Operator biomechanics

Questions Answered

Through scientific analysis, we can help you answer pertinent questions such as:

  • Why did the forklift tip-over?
  • Did the machine's guarding meet applicable safety standards?
  • Why did the load fall on the operator?
  • Were they any safety devices available at the time the machine was built that could have prevented the accident or mitigated injuries?

Case Examples

Missing Locking Pin:

A forklift operator was lifting a large load while an assistant was standing nearby observing the operation. Suddenly, one fork shifted its position and caused the load to fall onto the assistant, causing a severe crush injury. Upon inspection of the machine, Technology Associates identified a missing fork locking pin, which allowed the fork to move unexpectedly and caused the accident, indicating that the accident was the result of improper maintenance.

Forklift Intrusion:

The driver of an upright lift truck crashed into a metal railing when the truck's brakes malfunctioned. The broken railing intruded into operator compartment causing serious leg injuries. We created a biomechanical model to show that the intruding railing caused the injury, as opposed to the defense's claim that the operator stuck her foot out. We also showed that a door would have been an appropriate safety device that would have prevented her injuries, resulting in a substantial jury award.

Forensic Engineering Experts: Machine Guarding

By: Dr. Irving Ojalvo

The primary function of all guarding is to prevent an operator or bystander from being injured by a potentially dangerous portion of a machine. Often the hazard involves moving parts with the potential to cut, crush or draw-in body parts, although barrier guards may also be necessary when electrical, thermal or chemical dangers are present.

The Distribution of Pedestrian-Backing Vehicle Accidents by Backup Alarm Status and Vehicle Type

By: Dr. J.P. Purswell

The purpose of the current study was to update and expand upon an earlier study performed to review and categorize OSHA accident investigation records for pedestrian-backing vehicle accidents according to whether the backing vehicle had a backup alarm and whether the alarm was installed and functioning as intended. The current study includes an analysis of additional records as well as the business type (SIC code) of the employer.

Automated Retrieval System Failure Results in Catastrophic Fire at Storage Facility

By: Bill O'Donnell

The largest storage rack/ retrieval system, larger than two football fields and eighty feet wide was constructed to store 108 million pounds of paper products. On July, 2002, after two months of use, the facility collapsed and sparked a fire that destroyed the entire structure and 45 million pounds of paper. Nearly 50 fire departments responded to the inferno, which burned for three weeks. The owner of the facility sued a number of companies that included the contractor that designed and built the structure, a subcontractor, and the company that supplied the 110 foot steel columns.
