Description

ACIMEX, the leader for the industrial handling of heavy loads, is an expert in the manufacture and design of segment erectors. Ask for a quote for a model of erector with high technical added value that will match your expectations. The ACIMEX segment erector operates in tunnels and handles the gripping, positioning and depositing of standard and invert segments. Located behind the TBM drilling head, inside the shield, the erector is connected to the TBM columns by two cylinders to position the segment on X, Y and Z to form a ring. This handling device, which can rotate through 360°, provides optimum safety in extreme environments. Fitted with 2 lateral suction cups fixed under the chassis and a central suction cup with vertical hydraulic movement, the ACIMEX segment erector works by means of a vacuum pump mounted on a pendulum and a rotating union for the arrival of the vacuum. The chassis can be rotated and the trim adjusted up to +/-5°. The erector is also fitted with 3 solenoid vacuum valves and 6 vacuum and pressure sensors (three 4-20 mA vacuum switches and 3 pressure gauges). Finally, it should be noted that the supply voltage for this CE certified handling device is 400V 3-phase and its maximum load capacity is 20 tonnes. ACIMEX segment erectors are used in the largest tunnelling machines in the world In 2013, NFM Technologies called on the technical expertise of ACIMEX by ordering a custom built erector for the construction of the concrete ring on the largest TBM built in France (15.08 m in diameter). As a matter of interest, the largest erector ever built was also manufactured by the company.
