The hydraulic cylinders inside forklift attachments that eliminate manual fork adjustment. Fork positioner cylinders set the fork spacing hydraulically \u2014 from the operator’s seat \u2014 matching any pallet width in seconds. Side shift cylinders move the entire fork carriage left or right for precise load placement without repositioning the forklift.<\/p>\n

Fork Positioner vs Side Shift \u2014 Two Different Functions<\/h2>\n
<\/div>\n

\"Forklift<\/p>\n

A fork positioner adjusts the distance between the two forks. Without a positioner, the operator must dismount, pull the locking pin on each fork, manually slide the forks to the new spacing, and re-lock the pins \u2014 a process that takes 3\u20135 minutes per adjustment. A hydraulic fork positioner does this in seconds, from the operator’s seat, controlled by a valve lever or joystick. The fork spacing cylinder sits inside the attachment frame, connected to each fork arm by a linkage mechanism.<\/p>\n

A side shift moves the entire fork assembly \u2014 both forks together \u2014 left or right by 100\u2013150 mm from the mast centreline. This allows the operator to fine-tune the load position without repositioning the forklift itself. The side shift cylinder is mounted horizontally across the carriage and pushes the fork carrier along a rail. It eliminates the need for precise forklift positioning on every pick and place cycle \u2014 saving time and reducing tyre wear from constant steering corrections.<\/p>\n

Both attachment types are available as integrated units (positioner + side shift combined) or as standalone attachments. Korea Ever-Power supplies the hydraulic cylinders for all configurations. Browse the complete forklift hydraulic cylinder<\/a> range.<\/p>\n<\/section>\n

Why Do Attachment Cylinders Operate at Higher Pressure?<\/h2>\n
<\/div>\n

The fork positioner and side shift cylinders operate at 18\u201325 MPa \u2014 higher than the standard forklift tilt cylinder (18.1 MPa) and steering cylinder (16 MPa). The reason is space constraint:<\/p>\n

\n
\n Compact Bore, High Pressure<\/strong><\/p>\n

The cylinder must fit inside the attachment housing \u2014 there is limited space between the fork arms and the carriage frame. A smaller bore at higher pressure produces the same force as a larger bore at lower pressure, while occupying less space.<\/p>\n<\/p><\/div>\n

\n 35 MPa Burst Rating<\/strong><\/p>\n

The 1.4\u00d7 safety factor (25 MPa working \u2192 35 MPa max) accounts for shock loads when the forks contact pallets, racking, or the ground during positioning. The attachment cylinder experiences more impact loading than a mast cylinder.<\/p>\n<\/p><\/div>\n

\n \u03a6125 Heavy-Duty Option<\/strong><\/p>\n

The EP-HCYY11112030 at \u03a6125 bore and 25 MPa is designed for heavy-duty clamp or rotator attachments \u2014 where the cylinder must grip, compress, or rotate loads up to several tonnes. At 38 kg, this is the heaviest cylinder in the forklift attachment range.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/section>\n
