A jack hoist is a hand-operated mechanical hoist that can move heavy objects without external power. It has three transmission selections: in, out, and free. It is used by firefighters and emergency response teams and is also useful for moving heavy objects on farms or in garages.
A jack hoist is a hand-operated mechanical hoist capable of moving very heavy objects that require no external power source other than the strength of the operator’s arm. Unlike a winch, the hoist does not store cable on a reel. The cord is simply passed through the machine with the hook end facing the object being moved, while the excess is held in a spool behind the tool. The grab hoist must be securely anchored to a solid or heavy object to provide the strength needed to move the lifted object towards the machine.
The jack hoist offers three transmission selections: in, out and free. The “in” position allows the gripper to retract the cable or lift the object towards the machine. The “out” position allows the operator to feed the cable away from the machine. This feature is often used when you need to hang up on the object that requires winching.
The “free” position allows the cable to slide freely from the hoist. The free position is fine for the initial setup of the machine, however, if the free spool position was selected while there was a load on the machine, the cable would simply move through the catch hoist too fast to stop again . This is the reason for the out function which allows only a small amount of wire to be released at a time towards the object.
The hoist’s ability to move very heavy objects without the aid of electricity, gasoline or other fuels makes it a common rescue tool for firefighters and emergency response teams around the world. It can be used to move a wrecked vehicle, a vehicle that is blocking access to a response scene, or pieces of a damaged building. The tackle is considered a very capable tool which, in the right hands, often makes all the difference in being able to reach a victim or save a life.
Not just a lifesaving tool, the small portable winch comes in handy on the farm, garage or shop for moving heavy items too large to move by hand alone. While not intended for vertical lifting, the grapple lifter is very capable of feeding objects horizontally across a floor, road or driveway. Requiring only a small length of chain to secure the hoist to a solid anchor point, the tool is sold complete and ready to use by many tool, rescue and machinery dealers worldwide.
