Inquired Product	0.5 Ton to 1 Ton Mini Hydraulic Hand Manual Pallet Operated Stacker

RAMHOIST: would you kindly check the technical details of stacker in our website: http://www.ramhoist.com/lifting-handling-equipments/HandPalletStackers.html

we need to know the capacity and lifting height to move forward, thanks

Customer: Thank you for the information. I have went through your website, as a careful consideration. I would like to know more about the stacker with Fixed Straddle Leg and 1 Tone lifting capacity with at least 1 meter lifting height.

also as I need the details of the adjustable fork section. Because the Ac unit need to be tilted side ways so I have to know the details of fork section to make a suitable decision.

Appreciate that!

RAMHOIST: May i know the pallet size? in other words, we need to know the leg outer width, leg inner width and fork outder width.

besides, we need to know your quantity.

your request is customized product, thanks

Customer: Thanks for the quick response.

The component need to move is an AC unit which for Train-use. the image of the unit looks like this:

As you can see the unit is larger than normal pallet, I think this one with wider leg is perfect:

the point in this one is only about the yellow leg in image above. inner width of Yellow legs need to be larger than 1200mm? or you have the fixed dimension?

the fork width I like to use the fork option A which shown as below:

And option C is also a good idea, need to discuss on this part later. ( keep option C for now)

For quantity, I need one for now to check the function and how well of this solution can be used. because currently, we use forklift to move the AC unit, it is hazard and inconvenient. In the future, we may order more from you If this solution work perfectly, because we have a mounts of AC unit to do maintenance.

At last, Can you send me some dimension range of fork section of option A.

RAMHOIST:

1st is unadjustable fork, 2nd is adjustable fork, which one you need?

if the fork goes in below, then no problem, but if the fork goes into two holes (marked in blue), we need to know the distance of two holes, and the size of this two holes, we need to check whether the fork can goes into the holes.

Customer: Sorry about the late response. still need to discuss this to my supervisor about choice of option A or C.

But the inner distance between two holes are around 700mm, and the size of the hole is 200mm x 60mm.

I need to discuss this with my supervise, once the decision is made. I will give you details of all the request and probably order from you.

At this stage, I need a discussion with supervise because we want to make sure this solution will be performed perfectly and I will contact you ASAP!

RAMHOIST：We already had a suitable solution which would fit for your jobs well. However, we would like to know some further details as below, in order to provide the best option to you.

1.The overall size of the AC unit Length*Width*Height and its gross weight.

2.We want to know the road condition from the train to the maintenance workshop.Because the wheel of electric truck is relatively small, if there re wide or deep gaps or rail or other barriers on the road, it might be a problem for our truck to go through.The forklift you used however don't have this kind of problem, because they have large wheel. Please show us some pictures of the road conditon if possible.

Customer: As our discussion went properly, I have a new problem :Can you guys cut the frame in half of the mast?the figure shows the request:

I want cut the frame where shows in red rectangular.jpg

I want cut the frame where shows in red rectangular, in other word I only want 1 meter high in total height. because the 2080 mm mast will damage the train body and the unit only need to be lifting to 500 mm height above ground. And I want to know the height of the hydraulic cylinder h? the size of the Unit are :

HVAC unit specifications:

Length 2499mm

Width 1850mm

Height 500mm

Weighs 644kg.

Material casing Painted galvanized mild steel.

RAMHOIST

We will do some amendments based on this stacker. 1. Change the mast to 1meter height. 2. Change the fork to 1.85meter length (according to the size of AC unit) and the width between two forks to 0.7m, in order to fit the distance between two holes on the AC unit. The purpose to make the long fork is to leave enough space between the stacker and the train body. To lift the AC unit, you do not need to put the whole fork into the hole, just a part of it. In this way, there will be a safe distance between the stacker and the train body.

The fork will be similar as this.

Electric stacker is ways better than manual stacker, considering the fact of your jobs. You need to move a lot of AC units, not just one or two. Manual stacker need to lift the goods by manpower, which is only suitable for some easy lifting job, not like your regular ones. It’s not possible for you to use a manual stacker to do this kind of job all day long. So the electric stacker will be the better option for you.

Customer: Thanks for the information which you providing. As our discussion, we decide to keep the Manual hand jack stacker as the first priority. And we will have a further discussion about your ideas.

Also, I will send you some drawings in details about the actual dimensions in next two weeks. We can have a further discussion based on that. Because even after the stacker is arrived in the future, our team still need to do some more modifications on this stacker.

I will send you by email about the drawings in next two weeks.

Customer: Sorry for the late response, I just finished my vacation and will talk to the manager tomorrow. But we had discussed this before. I want to konw what is the longest length of forks you can provide and the length of the legs( Are the both legs are the same length as forks?) Also can you fabricate the mast of the stacker to 1 meter? and I want to know the total overall price and the period of shipment to New Zealand?

RAMHOIST: What is the longest length of forks you can provide and the length of the legs ( Are the both legs are the same length as forks?)

According to the size of the AC unit (2499*1850*500mm) and specifications of the stacker itself, we suggest the suitable fork length should be 1850mm. Legs and forks will be similar as below picture.

Also can you fabricate the mast of the stacker to 1 meter? and I want to know the total overall price and the period of shipment to New Zealand?

The mast can be 1 meter.

Goods will arrive NZ around 60-70days after the placing of order.

Why choose Electrical Stacker not manual one?

1. The size of AC unit is too large for manual stacker. If we add the fork length of a manual stacker to 1850mm, it will be unstable and will fall down if loaded. Because the weight of stacker itself is too small and can’t keep the balance when loading. The legs won’t help in this case. Think about the diesel forklift you used, if its weight is to be half or one-third of current figure, it can’t keep balance at all.

2. Manual stacker need to lift the goods by manpower, which is only suitable for some easy lifting job. We know how much power it takes to lift cargo up, it’s not possible for you to use a manual stacker to do this kind of job all day long.

Customer: Thanks for the information been provided, My car been theft last week I tried to send you the drawing and ideas but all the work are stolen with my laptop. but I still have hand drawing of the stacker.

which the fork have to tilted side ways and have capable tips in front also the whole panel need to be shift side way to fit the ac unit in the channel under the train. So I still need to add more components on it by our fabrication team.

By the usage of this stacker, we won't do this job all day long, may be once a day. And for unbalance issue, once two legs on stacker over the center of the mass of the Ac unit, it will not fall down ( legs must over 1.2 meter long)

Because I need figure out the modification to fulfill all the requirements I need to know the height of the fork panel?

If everything works out properly, we may start ordering in this month. So I need these dimensions.

RAMHOIST: According to your requests and working condition, if you want to take manual stacker, it means to develop a brand new model, not just some modifications. Because the AC unit you're going to handle is not suitable for manual stacker at the beginning. If you insist on taking manual stacker,we would need a MOQ of 50pcs, considering the low value of manual stacker, and great time and effort that should be spent in this job.If you okay with electric stacker,it will be no problem for you take 1pcs sample.

Customer: Sorry about the confusion. May be I didn't explain to you properly.

By modifications, I didn't meant to ask you do them all. what I need are the longer length of fork with long and wide legs. And the request of mast is around 1 meter high. These three points are all I need and keep all other designs same as original. About the drawing I sent to you is not what I request you to fabricate.

RAMHOIST: Already checked with our engineers about the fork and legs and all of them think those modifications are not workable. The weight of manual stacker is around 200-300kg, even less than the AC unit itself. If we add a long fork to the manual stacker for example 1.85m, the centre of gravity will move forward and the stacker will fall when loading. Even the long balance legs won't help in this case. Normal fork length for a manual stacker is only 1m, in order to keep it stable. Please think about the diesel forklift you used, they are equipped with counterbalance device to keep stable. But stacker don't have this device, so the weight of itself is the only thing that she can rely on to keep stable. That's why an electric can be modified, but a manual stacker can't, because the former one is more heavier.
