The safety hoist is an industrial tool used in roofing and remodeling to lift heavy materials. It works on almost any aluminum ladder and is made of lightweight aluminum, rubber bushings, and steel bearings. Different hoists can lift different weights, and some have add-ons like wider trays and motors.
A safety hoist is an industrial strength tool that has been introduced to the roofing and remodeling industry. Roofers used to carry roofing materials, which are almost always heavy, up ladders with the additional weight carried on their shoulders. Since its invention, the safety hoist has eliminated undue back strain and provided a more efficient way to lift roofing materials.
A safety hoist is a ladder jack application. This means it works on almost any aluminum ladder construction rated for the weight to be lifted. When the safety hoist is applied to the ladder, roofing materials can be loaded thereon and substantially lifted onto each rung of the ladder through the use of a lifting handle. When the operator pushes down on the jack handle, the safety hoist moves up another rung of the ladder until it reaches the desired height.
The materials used to manufacture safety hoists are usually lightweight aluminum, rubber bushings and steel bearings which allow the lifting tool to function smoothly. The plate that acts as a “table” for the materials is made of welded aluminium. It is supported based on the weight it was designed to lift.
There are different safety hoists that can load different weights on them. Choosing the right one for the operator’s intended use must be done with care. Overloading a safety hoist could cause the unit to fail, which can cause the hoist to fail to secure on a ladder rung and fall.
Many of the companies that make safety hoists also offer aftermarket add-ons and upgrades for their systems. Examples of such add-ons include wider tray surfaces that allow for more material to be lifted, and concave trays that can be attached to the original tray for lifting smaller workpieces or tools at once. This is useful for lifting powered nail guns and coils of nails. Some also offer lightly magnetized trays to prevent loose cover materials from sliding off the tray when lowering or lifting, possibly injuring the operator below.
Another feature that some companies have engineered into safety hoists is a motor. The motor performs the act of lifting the tray onto the ladder without having to be raised rung by rung. These units have an arm attached to them, and once engaged, the motor moves into a drive gear and pushes the tray up the ladder until the operator below hits the brake.
