Is It Necessary for a Scissor Lift To Be Completely Level?

Having a perfectly level surface is ideal when operating a scissor lift. However, manufacturers understand that job sites often involve uneven terrain. This section explores manufacturer guidelines for slopes and the factors impacting stability.

Manufacturer Guidelines on Operating Slopes

Most scissor lift manufacturers provide guidelines on operating the equipment on sloped or uneven ground. They specify the maximum slope rating in the operator’s manual and on the scissor lift’s identification plate fitted on the machine.

This maximum slope is determined after evaluating factors like the lift’s weight distribution, surface traction required for extra braking distance, and tilt sensors. Exceeding the rating poses risks like reduced surface traction, longer braking distances on slick surfaces, and potential tip-overs if the slope is too steep.

Factors Impacting Stability on Slopes

A few key factors determine how much slope a scissor lift can withstand before stability is compromised. Ground conditions like loose gravel or wet surfaces reduce traction and braking ability. The slope grade of the lift’s weight distribution and center of gravity also impacts stability. Improper load balancing or additional weight, like outrigger boards, can shift the center of gravity on a slope.

Surface irregularities like raised sidewalks or uneven gravel introduce variations in contact points and risk tilting. The operator’s skill in using proper stabilization techniques like slowing speeds based on conditions is equally important. Cross-checking the maximum slope rating specified for different load capacities and configurations helps determine if a particular slope can be accessed safely.

Assessing Slope Grade and Surface Conditions

Proper evaluation of slope grade and surface conditions is critical for safely operating aerial lifts like scissor lifts on uneven terrain. Understanding the actual slope is key to determining whether the equipment exceeds its rating.

Measuring Slope Grade Accurately

An operator can use several methods to accurately measure the grade of a slope before determining if it is suitable for their scissor lift. One recommended technique involves finding the vertical distance and length to automatically calculate the slope percentage.

Tools like a carpenter’s level and wood level can help measure how far the downhill end of a board is raised when placed on the sloped surface. This indicates the slope grade, which should not exceed the lift’s maximum slope rating.

Evaluating Surface Traction and Stability

Equally important is inspecting the terrain’s surface traction and stability. Loose gravel, uneven gravel, and wet or loose ground like sand can reduce surface traction and impact the lift’s ability to brake safely. Slick or unstable surfaces increase braking distances, posing risks. Operators must also be aware of any raised sidewalks, drop-offs, or other irregularities on the slope.

Conditions that may shift the scissor lift’s center of gravity or compromise the stability of outrigger boards must be addressed, such as reducing the lift’s load capacity accordingly or repositioning outriggers. Only smooth, stable sloped surfaces providing adequate traction for operating the scissor lift’s ID plate should be considered.

Stabilization Methods for Uneven Surfaces

When operating aerial lifts like scissor lifts on uneven terrain, it is important to implement stabilization techniques to improve safety and control. Proper stabilization can help prevent tip-overs.

Using Outriggers and Stabilizer Feet

Outriggers are a very effective way to increase the stability of scissor lifts when used on sloped or uneven ground conditions. They work by expanding the lift’s base and lowering its center of gravity. Operators can add outrigger boards under the outriggers to further improve stability. This is especially useful on loose gravel or surfaces with irregularities, like raised sidewalks where the risk of tilting is higher.

Operating Techniques for Improved Control

In addition to mechanical stabilization, operators should use techniques that maximize control. Slowing surface traction based on conditions is key. Reducing load capacity suitably if the slope is too steep can evenly distribute weight.

Maintaining smooth, gradual movements per the lift’s manual prevents sudden shifts in the machine’s center of gravity. Always wearing a safety harness and tying to an anchor point on the lift improves safety on sloped terrain. Following manufacturer guidelines on maximum height and a safe working angle specific to each job site ensures safe operating practices.

Understanding a Lift’s Slope Rating Specifications

Every scissor lift is designed and tested to operate safely within defined parameters. Knowing a lift’s slope rating specifications allows operators to determine if a sloped surface can be accessed.

Identifying Maximum Slope in Manual and Plate

The maximum slope rating for a scissor lift is indicated in key areas for quick reference. Operators should familiarize themselves with where this specification appears – in the lift’s manual, on the manufacturer’s identification plate fitted to the machine, or marked by a decal on the platform. This ensures safe operating limits are never exceeded.

What Slope Rating Specifies

The slope rating considers factors like the lift’s center of gravity, weight distribution across its base, and safety systems installed. It specifies the maximum angle of inclination a surface can have for the lift to maintain stability under all foreseeable load and ground conditions.

Exceeding this slope rating invalidates the manufacturer’s safety testing and risks loss of control from tipping. Understanding this rating ensures lifts are only used within their intended design capacity.

Safety Considerations When Operating on Slopes

When operating aerial lifts like scissor lifts on sloped terrain, special safety precautions must be followed to prevent accidents. Additional fall protection and control measures are important.

Harness and Fall Protection

When working on slopes, operators must wear a full-body harness and lanyard connected to an anchor point designated by the manufacturer. This fall restraint system prevents injuries from falls by limiting free fall distance. Operators must also be aware of uneven terrain, drops, or other hazards that could lead to tip-overs if the lift becomes unstable.

Reducing Speed and Load

Speed and load capacity adjustments can further reduce risk. The operator manual specifies reduced speed limits based on slope grade and surface conditions to allow for safer braking and control. Heavier loads may also affect the lift’s center of gravity on inclines.

Distributing weight evenly and reducing load if required helps maintain stability. Cross-referencing the lift’s rated capacity at different angles ensures safe operation.

When To Avoid Operating on Slopes

While most scissor lifts provide versatile access, some sloped surfaces simply pose too great a safety risk. Knowing when to utilize alternate methods is important.

Conditions Exceeding Manufacturer Guidelines

Operators must never use aerial lifts on slopes beyond the equipment’s rated capacity. Ignoring maximum slope, height, or load specifications can lead to loss of control and tip-over accidents. Aerial lift operators must exercise special caution on slick or unstable surfaces that lack proper traction.

Alternative Access Methods

When a slope is too steep, the smart choice is to select safer access. Scaffolding or a telescopic boom lift with a larger working angle may be better options. Mobile elevating work platforms have a four-wheel drive for rough terrain access. For very short-term tasks, ladders can be used with fall protection. Following manufacturer guidelines ensures lifts are deployed responsibly within their operational design range.

Taking time to properly assess site conditions helps determine if a slope poses risks beyond an aerial lift’s capabilities. Not using the equipment in situations it was not intended for helps maintain safety.
