Probst TSZ-UNI-800 and TSZ-MAXI-800 Concrete Step Lifters
The Probst TSZ Concrete Step Lifter range is designed for safe, efficient handling of concrete elements such as kerb stones, Kassel kerbs, Trief kerbs, L-shaped blocks, and unusual or conical-shaped steps. Suitable for use with a lifting device or crane hook, both the TSZ-UNI-800 and TSZ-MAXI-800 models deliver dependable grip, control, and versatility for professional landscaping, construction, and hardscaping tasks.
These German-engineered units are fitted with automatic release functionality, enabling a fully automatic switch-over from “full” to “empty” once the product is laid in position. This makes the Probst TSZ range an ideal solution for handling heavy or awkward concrete elements without manual intervention.

FAQs – Probst TSZ-UNI-800 and TSZ-MAXI-800 Concrete Lifters
What’s the difference between the TSZ-UNI and TSZ-MAXI models?
The TSZ-UNI-800 handles kerbs and blocks from 50–600mm wide, while the TSZ-MAXI-800 is designed for much larger blocks and stones from 850–1100mm wide.
How does the automatic release mechanism work on the Probst TSZ?
Once the load is placed and weight is off the jaws, the lifter automatically resets to the open position, eliminating manual unclamping.
Can Probst TSZ models be used with a crane or chain hoist?
Yes. Both TSZ models include a lifting eye compatible with crane hooks, slings, or hoists.
Are spare Probst rubber pads available?
Yes, replaceable rubber grippers and steel fingers are available as optional accessories depending on your application.
Can I grip conical kerbs securely with the Probst TSZ-UNI?
Yes. The 185mm internal height ensures the lifter can grip beneath the taper of conical kerbstones for a secure hold.
