The Raymond straddle is achieved by the leg spacing as described above. It was a fairly common option. I had AC trucks with that configuration. You need a Raymond sales rep.... Their web site has pretty pictures....
That said, the pentagraph was always in the way...
I did the same and the only thing Raymond offers is walk behind straddle stacker. That seems a bit strange as Raymond first entry into the narrow aisle products was a stand-up rider straddle unit. I know the market is very small (less than 100 units sold in a year) for these type units so they probably stopped offering it or only offer it as a "special" non price book version.
But this might help Clark still offers a stand-up straddle unit Clark model NSR 22 & 25 (4500 & 5000 lb lift capacity).
I went on Raymond web site and could not find a straddle truck. What is the model #?
The reason that the customer can't use a reach truck is because of the visibility through the pantograph at low levels and the height of the pantograph when it is collapsed does not allow him to access his top beam without hitting the ceiling.
Rather than go thru all that work & expense of getting a carriage, buy a standard reach truck with the out riggers spaced wide enough to fit the users pallet - rule of thumb is the ID should be a 4" wider (some people might say you need only 2") than the pallet width being used (in straddle truck operations all the pallets must be the same width. Also, make certain the unit is fitted with load wheel protectors on the leading edge of teh straddle arms (saves a lot of load wheel damage/repairs & down time. Most pantagraphs have the carriage supports & rollers built integrally - you woudl be taling about buying a straddle truck carriage to fit the machine - that would be more rare than find a straddle truck)
Forkingabout is correct Raymond offers their stand up reach truck as a straddle.
Any of the Raymond reach truck's any good to you?
Toyota / BT are all part of the same family as Raymond.
