Kinds of Man Lifts
Designed particularly to vertically hoist employees to higher areas, scissor lifts are common in the construction industry to help transport or raise workers form one place to another. Man lifts are power-driven and offer platforms or steps and special handholds to provide safe transport. The kind of construction work being carried out would decide exactly which kind of man lift would be utilized in a project.
Electrically Insulated Man Lifts
According to Man and Material Lift Engineering, the man lift most preferred for working in close proximity to electrocution hazards are electrically insulated man lifts. The electrically insulated man lifts provide protection to personnel against accidental electrocution. These machines follow the American National Standards Institute A92.2 Category C, 46kV Rated. These electrically insulated man lifts offer fiberglass insulated booms, fiber optic control cables and are operated on nonconductive hydraulic hoses which serve to reduce ground error.
Scissor Lifts
Scissor lifts are a special type of aerial man lift that is meant to transport personnel vertically to difficult-to-reach places. The scissor lift derived its name because of the scissor type of design of the folding supports that could lower and raise the platform. To be able to hoist the lift, each one of the folding supports is opened so as to extend the platform to higher heights.
Scissor lifts can be either manually or hydraulically lifted. Hydraulic systems allow the scissor lifts to descend with just a release of hydraulic pressure, instead of depending on power. Because the potential of mechanical malfunctions preventing the platform from descending to the ground rapidly is eliminated, at the end of the day, hydraulic systems make safer scissor lifts.
Capacity
Man lifts are designed in a huge range of weight capacities. Some man lifts have the capability to only hold numerous people while others have the ability to hold one individual. Scissor lifts and platform lifts are more conducive for transporting numerous people, because boom lifts have less space located in their bucket.
