What is a cable hand puller?
A cable hand puller, also known as a cable puller or a come-along, is a manual tool used for pulling or tensioning heavy objects or materials, typically cables or wires. It is designed to provide mechanical advantage and leverage to the user, allowing them to generate a significant amount of pulling force with minimal effort.
How to use the cable hand puller?
Relasing the cable before pulling
Step 1 – Disengage main ratchet drive
First, locate the drive pawl spring on the lever handle and pull it to the ‘up’ position to disengage the main ratchet drive.
Step 2 – Attach load hook
Attach the load hook to the load you are going to pull. If you have two load hooks they can be connected together to form a loop.
Step 3 – Release cable
To allow the cable to run freely, squeeze up the stop pawl trigger. Walk with the cable puller back to the anchor point.
Step 4 – Release stop pawl trigger
Once you reach the anchor point, release the stop pawl trigger and make sure it is fully engaged back into the ratchet sprocket.
Step 5 – Attach anchor hook
Attach the anchor hook to the anchor point that you will be pulling from.
Pulling the load
Step 1 – Engage drive
To begin pulling the load the drive will have to be engaged. Push the drive pawl spring into the down position which will enable the main ratchet drive pawl to engage with the ratchet drive sprocket.
Step 2 – Crank lever
Start cranking the lever handle backwards and forwards to begin ratcheting. Every time the lever handle is moved towards the anchor point the load is pulled.
Step 3 – Pull load
Keep moving the lever handle back and forth until the load is pulled to the desired position.
Step 4 – Secure load
Make sure you secure the load that has been pulled so it does not move when the tension is released.
Releasing the tension after pulling
Step 1 – Disengage ratchet drive
First push the drive pawl spring into the up position to disengage the main ratchet drive, this will loosen the cable.
Step 2 – Push lever handle
Push the lever handle fully over to the anchor hook side – this will force the spring loaded stop pawl mechanism pin down, then slowly raise the lever handle.
Repeat these actions until the cable tension is released.
Step 3 – Loosen cable
Now the cable tension is eased, squeeze up the stop pawl trigger to release it from the cam and gently pull back on the puller to loosen the cable further.
Step 4 – Push drive pawl spring
Leave the load hook attached to the load you have pulled and push the drive pawl spring into the down position.
Step 5 – Wind cable
Hold the anchor hook in one hand and gently pull against the load while moving the lever handle back and forth to rewind the cable back onto the drum.
