Understanding Scissor Lifts

Types of Scissor Lifts and Their Specific Applications

Scissor lifts come in various forms, each designed to cater to specific tasks and environments. Electric scissor lifts, known for their quiet operation, are often utilized indoors on flat, hard surfaces where emissions and noise need to be kept to a minimum. Rough terrain scissor lifts boast reinforced tires and four-wheel drive capabilities, making them suitable for outdoor work where uneven ground conditions prevail. Additionally, there are pneumatic scissor lifts that operate using air pressure, ideal for environments where combustion engines are not allowed due to the risk of contamination or explosion. By understanding the different types of scissor lifts and their applications, operators can choose the most appropriate lift for their particular job, ensuring efficiency and safety.

Basic Mechanics of Scissor Lifts

At the heart of a scissor lift’s design is the crisscrossing ‘scissor’ mechanism, which provides stability and elevation. This is typically powered by hydraulic, pneumatic, or mechanical means. Hydraulic scissor lifts use pressurized fluid to move the lift’s platform up and down. The pressure is generated by a motor, which pumps the fluid into the lift’s cylinder, extending the scissor mechanism. Pneumatic lifts operate on air pressure, making them less prone to leaks and environmental concerns than hydraulic systems. Mechanical lifts, on the other hand, employ a screw thread or rack-and-pinion system to achieve lift. Understanding these mechanisms is crucial for operators, as it affects maintenance routines, emergency procedures, and the lift’s operational limitations.

Potential Hazards Associated with Scissor Lift Operation

Despite their indispensable utility, scissor lifts can pose several hazards if not operated correctly, and recognizing these potential hazards, operators and site supervisors can take proactive steps to mitigate risks and foster a safety culture on the job site. Tipping and collapses can occur when lifts are used on uneven terrain or are overloaded. Falls from height are a risk, notably if the operator neglects to use a harness or the guardrails are compromised. Electrocution is a threat if a lift is maneuvered close to power lines or energized conductors. Mechanical faults can also lead to accidents, making regular inspections and maintenance a non-negotiable part of the scissor lift operation.

Pre-Operational Safety Checks

Inspecting the Scissor Lift Before Use

Before each operation, it is essential to conduct a thorough inspection of the scissor lift to identify any potential issues that could lead to malfunctions or accidents. This routine should be as meticulous as it is systematic, following a checklist that includes but is not limited to:

  • Examining the integrity of the guardrails
  • Ensuring the stability of the platform
  • Checking for hydraulic leaks or damaged components
  • Verifying that the tires are in good condition and properly inflated
  • Testing the controls to confirm they respond correctly

The lift should also be checked for any loose objects that could be hazardous when elevated. A pre-operational checklist not only prevents the oversight of critical safety aspects but also helps in maintaining the longevity of the equipment. Should your scissor lift not pass your pre-operation inspection, please call our scissor lift company immediately.

Assessing the Work Environment for Potential Risks

The environment where the scissor lift will be used must be scrutinized for potential hazards. This assessment involves checking for uneven ground that could compromise the lift’s stability, identifying overhead obstructions that could pose collision risks, and being aware of nearby power lines that could create electrocution hazards. It’s also important to consider environmental factors, such as wind ¹ – after all, we are in the Windy City – which could affect the lift’s operation at height. Each potential risk identified must be addressed appropriately, whether by relocating the lift, stabilizing the ground with appropriate support, or implementing measures to guard against electrical hazards.

Ensuring All Safety Devices are Functional

Safety devices on scissor lifts are critical components that must be in working order before operation. These include tilt sensors that alert the operator if the lift is at a dangerous angle, descent alarms, emergency stop buttons, and foot switches that require the operator’s presence for the machine to operate. Testing these devices should be a non-negotiable step in the pre-operational checklist. Personal protective equipment (PPE), such as harnesses and lanyards for the operator, must be inspected for wear and defects. Ensuring that all these safety measures are in place and functional is not just a regulatory requirement but a fundamental responsibility of the operator and employer to safeguard the well-being of all personnel involved.

In the context of scissor lift operation, PPE can mean the difference between a minor incident and a life-threatening accident. The harness and lanyard system can prevent a fall from height, the leading cause of serious and fatal injuries in aerial lift operations. Hard hats and safety glasses shield against head and eye injuries, respectively, which are common in construction and industrial settings. When used consistently and correctly, PPE significantly reduces the risk of injury, providing an indispensable safety net for those working at heights.

Safe Operation Procedures

Guidelines for Safe Ascent and Descent

The movement of a scissor lift, whether ascending or descending, should be approached with meticulous care. Operators are instructed to ensure that the platform is clear of tools or debris before moving and to keep body parts inside the confines of the rails at all times. Smooth operation is key, avoiding sudden stops or starts, which can cause instability. When ascending, the lift should be raised vertically without any tilting, and during descent, operators must ensure that the descent path is clear of personnel and obstacles. Additionally, operators should never climb on the guardrails to reach higher areas; for example, if a 19-foot scissor lift does not reach, a 26-foot scissor lift should be used.

Weight Limit Compliance and Load Distribution

Every scissor lift has a maximum load capacity which must be respected to maintain stability and prevent mechanical failure. Operators need to be aware of the lift’s weight limit and must calculate the combined weight of personnel, tools, and materials before use. Note: Our 19 foot scissor lifts have a load capacity of 505 pounds. Even distribution of the load on the platform is also crucial to prevent tipping. Loads should be centered on the platform and secured if necessary to prevent shifting, which could disrupt the lift’s balance.

Maneuvering the Lift Safely Within the Worksite

Navigating a scissor lift on a job site requires vigilance and an awareness of the surroundings. Operators must follow designated driving paths and avoid hazardous areas with potential risks such as drop-offs, holes, or unstable surfaces. The use of spotters or ground guides can be crucial in tight spaces to guide the operator and ensure a safe path. All movements should be executed at a speed that is conducive to the operator’s control and the environmental conditions, taking special care during turns and reversals to maintain stability.

Best Practices for Working at Heights

Working at heights carries inherent risks that are magnified by improper practices. Operators should always maintain a firm footing on the platform and use guardrails or other approved anchorage points for fall protection. Tools and materials should be tethered or otherwise secured to prevent them from falling off the platform. When working at significant heights, it’s essential to monitor wind conditions as well, as strong gusts can destabilize the lift ¹. All operators should understand emergency descent procedures in case of power failure or other emergencies that require evacuation from height. Adopting these best practices helps ensure a safe and productive environment for everyone on the worksite.

Fall Protection Measures

Harness and Lanyard Usage

The deployment of personal fall arrest systems, including harnesses and lanyards, is crucial when operating a scissor lift. Operators are required to wear a full-body harness with straps that distribute fall forces over the thighs, pelvis, waist, chest, and shoulders. The harness should be connected to the lanyard, and the lanyard should then be attached to a designated anchorage point on the lift. This anchorage point is specifically designed to support the forces exerted during a fall. Operators must ensure the harness fits correctly and that all buckles are securely fastened. The lanyard length should be appropriate to prevent the worker from hitting the ground or the level below in case of a fall.

Guardrail Systems and Their Importance

Guardrails form an integral part of the built-in safety features of a scissor lift. These rails provide a barrier between the operator and the edges of the lift platform, thereby preventing falls. It’s imperative that all guardrail systems, including mid rails and top rails, are intact and secure before use. Operators should never lean over, sit, or climb on the guardrails, as these actions can lead to a loss of balance or structural failure of the guardrail.

Procedures to Follow in Case of a Fall

In the event that a fall occurs, it is vital that a clear procedure is followed. The fall arrest system is designed to stop a person’s fall safely, but it’s equally important to promptly rescue the individual to prevent suspension trauma ³. All scissor lift operators and spotters should be trained on the emergency procedures, which include notifying immediate supervisors, contacting emergency services if necessary, and employing the lift’s emergency lowering system if the situation and safety protocols allow. It is also advisable to have a fall rescue plan that reduces the time an individual remains suspended in a harness, as prolonged suspension can lead to serious health complications.
