Product catalog summary

Introduction
The SARLIFT 2500 is a heavy lifting system developed by Sarens Special Project Department. It is designed for handling heavy loads in confined spaces where cranes are inaccessible. The system has been tested and successfully operated in various configurations, including SARLIFT 750 and SARLIFT 1000.

General Information
The SARLIFT system is a multi-functional gantry lifting system comprising several key components:

Four columns with cylinders and locking mechanisms, constructed from reinforced profiles.
Two longitudinal cross beams connecting the towers, with variable lengths and sizes.
Longitudinal bracings connecting the towers, designed modularly with standard elements.
Transversal top connection beams linking the towers, available in various lengths and sizes.
Transversal lifting beams equipped with lifting lugs for load handling.

Additional configurations include stay arrangements and skidding systems for enhanced flexibility.

Working Principle
The lifting process involves a four-step cycle:

Release/close top and bottom anchor clamps, retract cylinder, load supported by top clamps.
Release/close bottom clamps, extend cylinder to transfer load to bottom clamps, free top clamps.
Release/close top clamps, retract cylinder to transfer load back to top clamps, free bottom clamps.
Release/close bottom clamps, cylinder climbs one stage higher, lifting the load.

Characteristics
The SARLIFT 2500 system is designed according to:

DNV rules for marine operations.
EUROCODE 3 for steel structures.
NS3472 for steel structures.

Each setup is recalculated and verified per local regulations. Key specifications include:

Lifting capacity per column: 250 tons.
Column footprint: 1,000 mm x 1,000 mm.
Standard column height: 2,500 mm.
Column element weight: 2,000 kg.
Minimum height: 2,000 mm.
Stroke: 500 mm.
Maximum pressure: 275 bar.
Hydraulic power: Electric (380 V – 63 A).

SARLIFT 2500 250TON Working principle Funktionsgrundregel Werkmethode Principe de fonctionnement • Step 1: Both top and bottom anchor clamps are released/closed (=blocking), the cylinder completely retracted. The load is supported by the top anchor clamps; • Step 2: The bottom anchor clamps are released/closed (= blocking), the cylinder is extended – transferring the load from the top anchor clamps to the bottom anchor clamps – until the top anchor clamps are set free and the top anchor clamps are actuated/opened (= unblocking). The cylinder is extended up to the maximum stroke; • Step 3: The...
