TBM Backup

TBM BACKUP
The expertise gained from the design and manufacture of machinery and equipment for the transfer of aggregates (sand, gravel, stones) for concrete industries and for quarries and mines, have enabled us to expand our product offering and services to high-tech and specialised equipment and machinery, which are subject to particularly severe operating conditions, such as special machines for underground use (TMB Backup systems).
Our machines are at work around the world on the most important projects for the digging of tunnels.

Belt Conveyor

We produce:

Conveyor belts for spoil mining sized as needed, and primarily consist of:

  • Rubber conveyor belt type FLEXIFER 250 4 + 2
  • Backhoe loader with flat rollers with supports
  • Rubberised control roller with supports
  • Return roller with supports

Motor unit composed of three-phase motor, mechanical or electronic variator, reducers, chain transmission screw conveyor and belt reducer

Segment Handling Hoist

We produce segment handling hoists
These carts carry the precast tunnel lining, in suspension, from their storage area to the segment feeder sled.
Are produced in various types and attachment systems and sized according to the space required on site.
Can be equipped with directional and rotating arm for precise positioning in the release phase and control pad or remote control.

Segment Feeder

We produce systems for any type and size of feeder

Muck Car Pusher

We build muck car pushers designed for pulling wagons along the rail in the tunnel.
The wagons are hitched using a mobile arm and moved along the rail to a distance equal to the length of the wagon, this allows the second arm to fit the next wagon by repeating the action. They are equipped with hydraulic motors and are controlled from the pulpit and/or radio transmitter.

Pea Gravel Box Conveyor

We produce conveyors for the lifting and lateral movement of pea gravel boxes from railcar to backup TBM.
They consist of:
No. 4 hooks for attaching the trailer
No. 4 lifting arms
Transfer trolley
Main trolley (for placement in longitudinal direction)
All movements are controlled by a keypad and/or remote control, and produced using hydraulic
cylinders.

Pea Gravel Trolley

We produce trolleys for the transfer of pea gravel.
Designed according to the needs and size of the tunnels, they primarily consist of:

  • Rubber conveyor belt type FLEXIFER 250 4 + 2
  • Flat rollers with supports
  • Rubberised control roller with supports
  • Return roller with supports
  • Exhaust damper with manual control
  • Customisable geometry and cube hopper
  • Sectioned material support grid
  • Additional side discharge screw conveyor complete with removable terminal extension (if required)

Motor unit composed of three-phase motor, mechanical or electronic variator, reducers, chain transmission screw conveyor and belt reducer

Pea Gravel Buffer Bin

Our conveyors for the transfer of pea gravel are designed and manufactured according to the requirements and the dimensions of the tunnel, and primarily consist of:

  • Rubber conveyor belt type FLEXIFER 250 4 + 2
  • Flat rollers with supports
  • Rubberised control roller with supports
  • Return roller with supports
  • Exhaust damper with manual control
  • Customisable geometry and cube hopper
  • Additional side discharge screw conveyor complete with removable terminal extension (if required)

Motor unit composed of three-phase motor, mechanical or electronic variator, reducers, chain transmission screw conveyor and belt reducer

Pea Gravel Transfer System

We produce complete systems for the transfer of pea gravel intended for injection, from transport wagons to conveyor equipment

The system usually consists of:

  • Fixed container including no. 1 extraction screw feeder with motor
  • Inclined screw conveyor with worm screw motor
  • Mobile container including no. 3 pneumatic cylinders, no. 3 valves and no. 3 control pads

Alternatively, we produce a system composed of:

  • Mobile container complete with rubber conveyor belt with three-phase gearmotor, mechanical or electronic variator, chain transmission screw feeder and belt-reducer
  • Inclined screw conveyor for transfer of pea gravel controlled by geared motor positioned using pneumatic cylinders
  • Mobile container complete with rubber conveyor belt with three-phase gearmotor, mechanical or electronic variator, chain transmission screw feeder and belt-reducer
  • Inclined unloading screw conveyor controlled by geared motor
  • Horizontal unloading screw conveyor with two outlets selectable using manual shutters, and controlled by a geared motor.
  • Concrete transfer containers (Bulk Cement Transfer System)
    We produce complete systems for the transfer of loose cement from storage silos to tunnel excavation face.

The system usually consists of:

  • Fixed container including no. 1 extraction screw feeder with motor
  • Inclined screw conveyor with worm screw motor

Mobile container including no. 3 pneumatic cylinders, no. 3 valves and no. 3 control pads
