What is a Scissor Lift?
Scissor lifts are a type of manlift that is commonly used in construction and facility maintenance to raise employees and their tools to working heights.
The scissor lift integrates a power system and a control system, working in tandem to achieve efficient elevation. This symbiotic relationship involves the control system, powered by electricity, diesel, or compressed air, operating on the same principle. The process entails driving the pressure pump to increase hydraulic pressure in the cylinder, pumping hydraulic oil into the sleeve cylinder, and supporting the lift arms to achieve elevation using 220V or 380V phase change electricity.
Functioning as a mechanical apparatus, the scissor lift utilizes electric energy to facilitate the lifting or lowering of objects. Primarily deployed in high-altitude tasks across various industries such as enterprises, chemical, municipal administration, electric power, and transportation, it serves as a crucial tool in enhancing productivity and safety in elevated work environments.
Types of Scissor Lifts
Scissor lifts exhibit structural diversity, categorized into four main types: scissor cylinder type, aluminum alloy (column) type, crank type, and chain type. Each variant is designed for specific applications, offering distinct advantages in terms of maneuverability, ease of use, and lifting capabilities. These versatile lifts are well-suited for a broad spectrum of home-related tasks, providing reliable functionality and robust balance across various work scenarios.
The different types of scissor lifts include:
Electric Scissor Lift
“Electric scissor lifts stand out as eco-friendly alternatives, powered by batteries rather than combustion engines. Their operation produces no exhaust emissions or loud noises, making them ideal for interior use. Compared to diesel scissor lifts, electric counterparts are often more compact, with narrower platforms, making them well-suited for indoor applications. To safeguard floors during operations, non-marking tires are commonly employed. While electric scissor lifts may have smaller platforms and lower load-bearing capacities than their fossil fuel-powered counterparts (diesel, gas, or propane), their portability is a key advantage. These smaller lifts can be easily transported between job locations, either towed or mounted on various vehicles such as automated guided vehicles (AGVs), flatbeds, or railcars for specialized applications. The all-steel construction and twin shear scissor stack ensure rigidity and durability, contributing to a long operating life. With high-quality components, electric scissor lifts operate reliably and consistently, and their deep cycle batteries provide longevity throughout extended job durations.”
Hydraulic Scissor Lifts
Hydraulic scissor lifts offer versatile applications both indoors and outdoors, powered by either an electric motor or compressed air. The hydraulic system facilitates the lifting and lowering of the scissor lift by pushing or draining hydraulic fluid between cylinders. This mechanism allows hydraulic scissor lifts to find utility in diverse settings such as warehouses, construction sites, and infrastructure projects.
To operate a hydraulic scissor lift, the operator initiates the power supply, and a valve controls the flow of hydraulic fluid or compressed air. The fluid is then transferred from the reservoir to the operating cylinders through the scissor lift control system. For upward movement, the hydraulic cylinder extends, causing the scissor legs to spread apart and elevate the platform. To lower the scissor lift, the operator releases hydraulic fluid or decreases pneumatic pressure, allowing the scissor legs to retract.
The term “scissor” originates from the cross-braced mechanism resembling the arms of a pair of scissors between the base and the higher platform. Fixed installation lifts are commonly employed to transport goods from vehicles to a building’s goods receiving rooms across different floor levels. Additionally, mobile hydraulic scissor lifts, characterized by their compact and lightweight design, serve the purpose of moving cargo or large objects within a factory or workshop.
Diesel Powered Scissor Lift
Diesel scissor lifts are conventionally powered by traditional diesel engines. Unlike their electric counterparts, these lifts are less environmentally friendly, emitting noise and polluting exhaust fumes during operation. With larger platforms, diesel scissor lifts excel in outdoor construction projects and well-ventilated indoor spaces where engine noise won’t disrupt crucial communication among workers. Despite being less eco-friendly, diesel proves to be a cost-effective fuel option, delivering substantial torque at low RPM levels.
Heavy-duty variants of scissor lifts are prevalent, featuring larger platforms and enhanced load capacities. Certain models incorporate a hybrid powertrain, catering to the needs of closed job sites. Diesel scissor lifts stand out as some of the most powerful options, well-suited for demanding tasks. Particularly favored for outdoor assignments, robust versions, including those designed for tough terrain, excel on uneven ground. With expansive deck surfaces and high platform capacities, these diesel scissor lifts empower operators to efficiently manage bulky and heavy equipment.
Rough Terrain Scissor Lift
Rough terrain scissor lifts, classified as Elevated Work Platforms (EWPs), are specifically designed for robust outdoor applications, providing enhanced power to navigate challenging conditions. Fueled by combustion engines such as diesel, petrol, or LPG, they deliver the necessary strength to operate in harsh environments and lift substantial loads. These lifts boast increased traction and travel speed, facilitating safe maneuverability across expansive construction sites. Primarily tasked with elevating individuals and objects from uneven ground, they excel in challenging environments, enhancing productivity through positive traction, gradeability, and speed.
Rough terrain scissor lifts are equipped with gradeability as a crucial metric. Distinct from the operating angle, which represents the steepest gradient a machine can function on, gradeability specifically denotes the steepest slope a machine can ascend. In the accessibility industry, gradeability characterizes the incline a machine can successfully climb up or descend. These rough terrain lifts feature high-performance tires and 4WD capabilities, ensuring they have the necessary power to navigate steeper slopes effectively.
