Pallet Truck Lift Cylinder
Ultra-Compact \u00b7 Bore \u03a640\u201345mm \u00b7 Stroke 120\u2013155mm<\/span><\/h2>\n

The smallest, lightest hydraulic cylinder in the forklift family \u2014 yet it moves every pallet in the warehouse. The pallet truck lift cylinder raises the forks just 120\u2013155 mm: enough to clear the floor, lift the pallet, and transport it. Millions of these cylinders operate worldwide in electric walkie pallet trucks, rider pallet trucks, and manual pallet jacks.<\/p>\n

How the Pallet Truck Lift Cylinder Works<\/h2>\n
<\/div>\n

\"Electric<\/p>\n

The pallet truck lift cylinder sits vertically inside the truck’s main body, hidden behind the battery compartment or pump housing. When the operator presses the lift button (electric) or pumps the handle (manual), hydraulic pressure extends the cylinder rod upward. A linkage mechanism connects the rod to the fork arms, converting the short vertical cylinder stroke into fork elevation.<\/p>\n

The stroke is deliberately short \u2014 120 to 155 mm \u2014 because the forks only need to rise enough to clear the floor surface and lift the pallet clear of the ground. A typical pallet truck raises the load 85\u2013200 mm, depending on the linkage ratio. More stroke than this is unnecessary and would increase the truck’s overall height and weight.<\/p>\n

Lowering is controlled by a release valve. The operator opens the valve, and the weight of the load pushes the cylinder rod back down \u2014 gravity does the work. There is no hydraulic power required for lowering, which is why these cylinders are single-acting (pressure on one side only).

\n

Why the Extreme Rod-to-Bore Ratio (87\u201389%)?<\/h2>\n
<\/div>\n

At 87.5\u201388.9%, the pallet truck lift cylinder has the highest rod ratio of any forklift hydraulic cylinder. The \u03a635 rod inside a \u03a640 bore leaves only 2.5 mm of wall thickness on each side. This extreme ratio serves a specific purpose:<\/p>\n

\n
\n Minimum Envelope<\/strong><\/p>\n

The cylinder must fit inside the narrow body cavity of a pallet truck \u2014 often less than 60 mm wide. Every millimetre of bore diameter adds to the overall truck width. The compact bore keeps the truck profile slim enough to enter standard pallet openings (typically 90\u2013100 mm between stringer boards).<\/p>\n<\/p><\/div>\n

\n Load-Bearing Rod<\/strong><\/p>\n

The thick rod carries the full pallet weight (up to 2,000\u20132,500 kg on standard pallet trucks) through a short linkage. The rod functions more as a structural column than a hydraulic piston \u2014 the hydraulic system only needs to push the column upward, while the column itself supports the static load at height.<\/p>\n<\/p><\/div>\n

\n Low Oil Volume<\/strong><\/p>\n

The small annular area between bore and rod means very little oil is needed to extend the cylinder. This reduces the pump size, battery consumption (on electric trucks), and the operator effort needed per pump stroke (on manual jacks). A smaller hydraulic reservoir keeps the truck lighter.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/section>\n
