Air scissor lift the pressure relief valve to adjust the maximum rating

Hand pallet trucks fuel tank leak will cause the hydraulic cylinder does not rise up . For the following reasons :
the pressure is low , less than load. Check the pressure relief valve .
tanks into the air , will cause instability in the cylinder , the air should be excluded .cylinder relief valve into the dirt , then place in a normally open state of the valve , automatic oil back into the tank , no oil flowing into the fuel tank .the piston side in electric stacker contact with the cylinder head too tight will cause oil pressure get in, can not produce Air scissor lift  enough thrust to make cylinder operation.hand pallet trucks load is too large , the pressure relief valve to adjust the maximum rating, but not force continuous action of the cylinder .leak causes: hydraulic forklift cylinder and piston wear and the gap is too large, if the electric pallet trucks piston seals installed , it is because of wear or aging lost ring seal . Solution: Replace the Air scissor lift piston or replace seals.
if the electric truck tanks often use only a part of the local wear serious gap increases, the cylinder leakage. The workaround is heavy with the Pistons. The reason for this phenomenon is the rod seal too tight , the rod is longer, in part caused by sliding too much pressure , or sliding parts cylinder contamination .

liftstar Air scissor lift For large area and horizontal transport mainly occasions

for small footprint  or high shelves, with vertical stacker or electric forklift handling mainly the occasion, single-sided and double-sided shelves series tray tray shelves can be selected.

If the load on the shelves of a library or stereo 1T, but no plank shelves, steel shelves with built recommend tray. Steel structure built of steel pallet shelf load effectively solve the greater electric stacker the greater the weight of the product, the old problem of the high cost, the more important is the use of a wall thickness of about 2mm square steel rigidity reaches the upper shelf  are horizontal and vertical deflection ≤ 10mm stringent requirements, while reducing permanent deformation, and reduce costs.

For large area and horizontal Hand fixed lift table transport mainly occasions, if using manual hydraulic pallet trucks carrying the appropriate choice of single tray. For stacking the goods to the goods below at the bottom of the tray coincides with the end of the swastika sided tray or tray-type single well. If using a self-propelled motorized pallet trucks are suitable for handling not connected with the bottom of the foot of the nine-sided tray
