Set of 4 synchronized winches for maintenance work on a bridge

treuil synchronise 1

Presentation

This set of 2 double-stacked double drum winches was designed to be used during maintenance work on a suspension ridge in Istanbul (Turkey).

Two winches are connected to the samed load and are synchronized to ensure the horizontality of the platorm throughout its travel. Security is ensured by doubling the carrier wire rope.

A specific function or temporary desynchronization of the winches allows the adjustment of the balance of the platform if necessary.

Technical characteristics

Capacity: 2 x 3 t, power: 400 V, speed: 13 m/min, max. drum capacity: 2 x 600 m, rope diameter: 14 mm, synchronization of the drum by absolute encoders.

Winch for captive balloon

machines speciales 3

Presentation

A solution based on an electric haulage winch with the patented Dynamic Power Optimization (DPO) system allows a variator to adapt the speed of the winch to the required effort at all times, a rotary collector for the power supply to the balloon and the optical fibre, a manual emergency control for handling the balloon even without electricity.

Technical characteristics

Maximum brake retaining force : 1,800 daN (on the first layer). Fitted with 180 m of textile rope, upper and lower limit safety switch, an electrical unit including "Voltage present” and “Emergency stop” light on the box, variable speed drive using variable frequency, braking resistance... 

Specific solution for rapidly covering and uncovering the SNCF waggons used for the transport of merchandise

industrie 1

Presentation

A system on arms, installed on the platforms between two loading tracks. Each winch is positioned between two waggons, with four cable outlets (upline or downline on each of the tracks) allowing for the opening or closing of the covers of the SNCF waggons.
The manipulators are controlled by one single radio control, for both the winding and the unwinding of the cable. Before each movement, the operator temporarily selects the manipulator selected for the manoeuvre.

Technical characteristics

Effort: 150 daN, speed: 25 m/min (45 m/min rapid and empty), a 28m Ø5 mm textile cable with a protective handle, shackle and hook. These winches are also equipped with a deflector and cable maintaining pressure rolls.

Autonomous trolley for opening and closing waggons

machines speciales 4

Presentation

Motorized trolley powered by a battery designed to assist the users on the opening and closing operations of the metal or tarpaulin wagon doors. Once the trolley is installed along the wagon, the user hooks the wire rope of the trolley to the door and can start to pull. This system provides a greater comfort of use to the workers, preventing the musculoskeletal disorders at the same time.

Technical characteristics

The system is equipped with a load cell enabling to stop the pulling action once the maximal effort is reached. There is also a high speed (5 km/h) to move around the warehouse. This one is then reduced to 2 km/h during the pulling operations.

Footbridge winch

machines speciales 1

Presentation

Working in pairs, these winches are used to lift a footbridge.

For safety reasons they are equipped with a manual control.

Aeronautical winch

application specifique 1

Presentation

In march 2010, a well known european plan manufacturer trust HUCHEZ Engineering to develop a pulling electric winch allowing measuring the static atmospheric pressure in flight.

Used during the test fligths and installed in the rear of the plane, the winch measures the pressure of reference (measurment of "0") outside the aircraft via a pipe that is dragging between 60 and 120 meters behind its tail. This pipe allows bringing back the outside pressure to a pressure sensor (located on the winch) via a pneumatic slip ring.

Technical characteristics

Aluminium structure, pulling capacity of 150 kg, speed of 30 m/min, power 115 V (300 Hz to 800 Hz), wire rope capacity: 140 m in diameter 9.5 mm, precision of the pressure measure: 1 Pa. Winch equipped of the following functions: speed inverter wire rope guiding system, pneumatic slip ring, load measure, positioning measures (quantity of wire rope out), automatic positioning (length to reach)...

Cable manipulators

machines speciales 2

Presentation

Used in hostile zone, the cable manipulators are used to handle (branch maintenance) of THP plugs. The system is made of two independent motors and brakes.

Technical characteristics

SWL 600 kg on 4 wire ropes, speed of 1m/min.
