November 29, 2023The Science Behind Elevator Safety: How Elevator Braking Systems Work | Laddey Clark & Ryan LLP | New Jersey Personal Injury Attorneys (3)

Elevators have become an integral part of modern life, allowing us to move effortlessly between floors in tall buildings. While we may not often think about it, elevator safety is not something anyone should take for granted. Elevators are very complicated machines that require frequent maintenance and inspection to ensure they don’t malfunction and injure or kill their passengers. A critical component of elevator safety is the elevator braking system.

The Basics of Elevator Braking Systems:

Elevator braking systems are designed to ensure smooth and secure rides for passengers. They are supposed to stop the elevator smoothly, and without causing injury to the elevators unsuspecting occupants. They primarily consist of three key components:

1. Elevator Motor: Elevators are equipped with powerful motors that control the movement of the elevator car. These motors are responsible for lifting and lowering the car within the shaft. If the elevator motors are not maintained, the elevator can move faster than was designed and lead to potentially catastrophic failure of the elevator system.

2. Counterweights: Most elevators feature counterweights that balance the load in the car. These weights reduce the overall energy required to move the elevator, making it more efficient.

3. Brakes: Elevator brakes are the crucial safety component. They work to stop the elevator in emergency situations, and are supposed to prevent the elevator from falling or moving uncontrollably. These brakes require frequent maintenance to ensure they are working properly. They are designed to stop a fully loaded elevator and then some, so the stop experienced by someone in a lightly loaded elevator will be very severe.

How Elevator Brakes Function:

Elevator brakes work on a straightforward principle. When the elevator is in motion, the motor provides the necessary force to lift or lower the car. In normal operation, the brakes remain open, allowing the elevator to move freely.

However, several safety mechanisms are in place to protect passengers in case of an emergency:

1. Traction System: Many modern elevators use a traction system, which involves a cable attached to the car and counterweight. The brakes grip the cable, preventing the car from moving.

2. Safety Governor: Elevators have a safety governor, which is essentially a speed-sensitive device. If the elevator moves too fast or experiences a sudden drop in speed, the safety governor triggers the brakes. If the safety engages, the unsuspecting passengers would feel a very hard and destabilizing stop, possibly leading to some very serious injuries.

3. Door Interlocks: The elevator doors are interlocked with the brakes, ensuring that the doors cannot open unless the elevator is securely at a designated floor. These brakes can also trip the elevator if they are not properly maintained and cause a passengers to lose their balance or be injured.

In summary, elevator braking systems are a crucial part of elevator safety. These systems are designed to respond quickly to prevent an elevator freefall, but they can, by their very design, still cause very serious injuries to elevator passengers. In fact, the very fact that one of these braking systems was engaged is evidence that the elevator itself was not being properly maintained.

Our Verdicts and Settlements

  • $3,000,000 Settlement

    A 76-year-old woman was struck, lifted up and thrown to the ground by a school bus as it was making a turn within a parking lot. As a result, she sustained serious and catastrophic injuries including a lacerated spleen, pinched ureter (requiring a stent and surgery every six months), rib fractures, lumbar spine (lower back) fractures and multiple internal hematomas, among other injuries. A lawsuit was filed against the transportation company that owned the school bus, the driver of the school bus, the owner of the parking lot where the incident occurred, and the valet company who managed/operated the parking lot. During discovery, and following mediation, the defendants offered a global settlement of $3,000,000 to resolve the matter without further litigation.

  • $385,000 Settlement

    A 53-year-old man was rear-ended by an Amerigas Propane Truck, resulting in serious and permanent injuries to his neck (including three cervical herniations and two cervical bulges). He underwent a two-level disc replacement surgery in his neck. While awaiting trial in Sussex County, Amerigas offered $385,000 to resolve the matter and avoid trial.

  • $275,000 Settlement

    A 59-year-old woman was T-boned, resulting in a displaced fracture to her wrist. The fracture was operated on and left the woman with hardware in her wrist. The tortfeasor had a limited insurance policy of $15,000, which was quickly offered. A claim for underinsured motorist benefits was made against the injured woman’s insurance company, Allstate. Allstate offered an additional $275,000 to resolve the matter pre-trial.

  • $270,000 Settlement

    A 53-year-old woman was struck head on, resulting in two herniations in her cervical spine and post-concussive syndrome. She underwent a two-level anterior cervical discectomy and fusion. Tortfeasor carried minimum policy limits with Esurance for $15,000, which was tendered following the surgery. The injured woman sought compensation under her underinsured motorist policy with NJM. NJM offered an additional $270,000 to resolve the matter pre-trial.

  • $220,000 Settlement

    An 81-year-old woman sustained two herniations in her lumbar spine when the tortfeasor’s vehicle failed to yield to hers, causing a front-end collision. The injured woman ultimately required surgical intervention in the form of a two-level lumbar laminectomy. A complaint was filed in Hunterdon County, and Allstate for the tortfeasor offered $220,000 to settle the matter without the need for further litigation.

  • $413,500 Settlement

    A 13-year-old student was injured at recess when he fell on a concrete septic cover located in the center of the school’s soccer field. Specifically, the young boy injured his left knee when the knee landed directly on the septic cover. Two separate surgeries were performed to repair the fracture, and significant ligament injuries that had occurred in the fall. A settlement with the school, in the amount of $413,500, was reached prior to attending binding arbitration.

  • $300,000 Settlement

    Obtained a $300,000 settlement for a minor child, who was seriously injured from a dog bite that occurred in Vernon, NJ (Sussex County). The client, who was supposed to be supervised by the dog owner, was ultimately attacked by a pitbull and sustained multiple facial lacerations and scarring.Initially, the homeowner's Insurance Carrier, Homesite Insurance Company, refused to accept responsibility for the dog attack and attempted to disclaim coverage under the homeowner's insurance policy. Laddey Clark & Ryan’s passionate and vigorous representation ultimately led to the carrier tendering its full policy limits to settle the matter.

  • $250,000 SettlementObtained a $250,000 settlement for our client, who was seriously injured in a motor vehicle accident that occurred at the intersection of Quaker Church Road and Center Grove Road in Randolph Township, NJ (Morris County). The client was traveling through the intersection when a vehicle ran a red traffic light and caused the collision.As a result of the crash, the client sustained multiple neck and back injuries, ultimately requiring surgical intervention. We were able to secure the full policy limits from the other driver’s insurance company, GEICO, as well as the full underinsured motorist benefits (UIM) from the client’s carrier, Farmers Insurance.
  • $1,800,000 Verdict

    19-year-old girl is rear-ended and had a herniation in her neck that will eventually result in surgery. The insurance company for the other driver, Mercury Insurance, claimed all of the spinal damage was due to old age and only made a minimal settlement offer. The jury was able to see how much the spinal damage and constant pain impacted the future for this young woman.

  • $4,100,000 Verdict

    A 14-year-old girl’s father ran a stop sign and collided with a passing car. She suffered a herniation in her neck, which harms her ability to play the viola. She had been a serious candidate at Julliard. The insurance company, Allstate, offered $7,500 pre-trial, which forced this case into the jury’s hands.

  • $750,000 Verdict

    A woman leaving work at 1 a.m. slipped on black ice in the parking lot outside of her office building, fracturing her ankle. She worked at an international company that conducted business at all hours of the day. The company that was hired to perform 24/7 monitoring of the property claimed it had no idea that people would be working that late and therefore should not be held responsible for re-freeze situations. We successfully argued that the snow and ice removal company, which received weather alerts every two hours, should have known that there was a re-freeze situation, and that it was well aware people worked in this office 24/7.

  • $2,000,000 Verdict

    An elevator maintained by Schindler Elevator Corporation dropped and slammed to a stop in Stateline, Nevada, severely injuring one of the passengers. Schindler and its attorneys maintained throughout the case that it did nothing wrong despite the admissions of its own supervisors that it was not maintaining the elevators to the proper standards.

  • $5,000,000 Verdict

    A 72 year-old man slipped and fell on black ice outside a Wells Fargo Bank. He suffered a spinal injury and required emergency surgery that confined him to a wheelchair. Wells Fargo and the company it hired to clear ice from the property attempted to blame the victim, but we were able to convince the jury the ice was an ongoing condition caused by a poor drainage pipe.

  • $1,455,000 Verdict

    Аn 18-year-old woman was rear-ended on her way home from college and suffered a herniation in her lower spine. Her doctors said her injury would eventually result in a fusion surgery. The insurance company, New Jersey Manufacturers, offered only $50,000 to resolve the case before trial started. We were able to show the jury how the terrible injury to this young woman has dramatically altered her life, and the woman’s treating doctors showed how the damage to her spine is progressive.

  • $7,750,000 Verdict

    Schindler Elevator Corporation created false work reports claiming a secretary performed maintenance on an elevator at the Headquarters Plaza building in Morristown, NJ. The elevator eventually failed catastrophically, severely injuring the carpenter inside. The man will never work again and is now in constant pain from his injuries. This case was a retrial after a previous jury entered an award of $4,000,000 in the same case that Schindler was able to get reversed on appeal.
