Top-Contact Hydraulic Lifting
The illustrated SGJY has a top saddle, hand-pump connection, and release valve on the bottle body. Its literature permits upright use. Provide the load contact and base arrangement with the required installed height.
SGJY hydraulic bottle jacks provide top-contact lifting through a manually pumped ram. The catalog includes several height and weight configurations, including separately marked screw variants.

The table lists three 50t entries: 255/465 mm, 255/405 mm with a screw designation, and 300/480 mm minimum/maximum height figures. Specify the complete entry, rather than the capacity designation alone.

The ≤ signs retain the source table’s height qualifiers. Designations retain the catalog’s t label. Height differences are not presented as a separate hydraulic stroke specification.
For an upright lifting proposal, check the available height under the load against the chosen entry. Provide the required final height and the contact surface. The base must also fit the available support area.
Send the catalog designation, required minimum and maximum height, screw variant if applicable, load drawing, and quantity. For repeated 50t entries, include both height figures or net weight to identify the configuration.
For a product quote, include the load and unit, lift height, quantity, and electrical supply where relevant. For distribution or integration, describe the product range and market you work with. For product information or support, identify the model and describe your question.
