How to use ton hydraulic pull back ram?

A hydraulic pull-back ram is a specialised instrument used to bend car frames back into form physically. It is highly hazardous equipment if used wrong. Thus it is critical to follow the manufacturer’s recommendations about weight restrictions and use. Never operate a pull-back ram without first covering the chains with blankets, and always wear protective eyewear. Keep in mind that a pull-back ram is not the same as a push-type or push-out ram, which pushes out rather than pulls in. Also, you must always use the hydraulic pump that comes with your ram to power it, as alternative pumps may not match the valve on your ram correctly.

What do you need to keep in mind when using a hydraulic pull back ram?

Purchase a set of metal pull chains that are rated for the weight capability of your hydraulic ram. You may potentially use any chain as long as it is rated for the same weight capacity as your ram and fits on the hooks of your ram. When you utilise the ram, your chains will snap if they are weaker than the ram. This is a potentially hazardous error.

The pull-back ram comprises two cylinders that slot into one another, with the narrower cylinder always facing your car. Connect a pull chain to the hook on the ram’s narrower end. The shorter the chain that connects the ram to the vehicle, the better. If any of the S hooks come loose while you’re putting it together, reconnect them.

How can you use the hydraulic pull back ram?

Hydraulic rams are almost always utilised for exterior frames. Wrap the hook of the draw chain around the section of the frame that needs to be adjusted. You can use the ram as long as the hook fits neatly around the metal and does not move about.

Connect a pull chain to the hook on the ram’s thicker end. Next, connect the S hook at the end of your second pull chain to the hook on the other end of the hydraulic pull back ram. Slip the two hooks together to hold them together.

Wrap the pull chain over a solid vertical surface, such as a thick tree. If you don’t have any building tools, you’ll have to make do with an I-beam or a tree. A pull-back ram nearly always has its hook or tool. The bucket can also be used on an excavator, backhoe, or bulldozer.

Remove the chain links from the hydraulic ram’s thinner side. Next, remove your S hook and raise it to a link closer to your ram until your tight chain. The fewer the links on the vehicle side, the less likely the chain will snap. If you have a lot of extra chains, you can “double loop” it.

Make the chains taut by adjusting the chain connection on the opposite end. Make any necessary modifications to either end of the chain to keep the ram in a straight line with both chains. To tighten the ram, adjust your hooks to transfer them to various areas of the chains or modify the angle of the anchor.

Remove the cover from the hydraulic ram’s side. A tiny cap covers a valve on the thicker section of the pull-back ram. Take off this hat. This varies by the ram, but you generally remove the cap by twisting it counterclockwise or gently pushing it out of the valve.

The pump that came with your pull-back ram must be used. You cannot use another hydraulic pump since the valve and hose may not be precisely matched.

Connect the hydraulic pump hose to the valve on the ram’s side. It’s crucial to note that custom-made hydraulic hoses can significantly improve the fit and performance for specific applications. They are tailored to particular needs and can ensure optimal pressure handling and longevity. Moreover, they reduce the risk of mismatch or leak issues, which can jeopardize the operation. Take the hydraulic pump line with your ram and screw it into the ram’s valve, or push it in and spin the handle to tighten it. Before proceeding, double-check the connection to ensure it is as tight as possible. You will only receive enough pressure if your pump is correctly linked to the ram.

Insert the pump handle into the aperture on the pump unit’s top. Pull the hydraulic pump on the other end of the line as far away from the chain arrangement as you can without stretching the hose. Place it flat on the floor and insert the pump handle into the aperture on the pump’s top. Check the instruction manual for your ram to determine if you need to lock the handle in place before using it.

Put on eye protection to keep your eyes safe. If a chain snaps, there’s no telling where it’ll end up. Wear safety glasses to prevent loose chain fragments from shooting out and injuring you in the eye.

To remove the frame, carefully pump the handle. Next, lift and shut the handle of your hydraulic pull-back ram to compress it. Do this carefully so you can keep an eye on the form of the frame as you take it out. The pressure in the pull-back ram will apply pressure to the hook on your car and draw the metal out as you continue to move the handle up and down. The pressure may build up too quickly if you pump too quickly, causing the hook to rip through the metal frame.

Once the frame is in place, apply pressure to the handle to keep it in place until you achieve the desired position. When you’re finished, the chain and ram should return to their original positions. Consult your owner’s handbook to find out how to alleviate the pressure; generally, you turn a knob or flip a latch to allow air out and relieve the pressure.
