Multifunctional amphibian pipe carrier
Often pipelaying works are carried out in places with high soil moisture (swamps, tidal zone), which makes it difficult to deliver equipment and materials to the place of work. This reduces the efficiency and safety of pipelaying works. For these adverse work conditions, our company constructed a multifunctional amphibian pipeline carrier. The minimum ground specific pressure, a powerful pulling force and high stability of this pipe carrier help deliver, assemble and weld pipes efficiently and safely.

Main components construction and technical characteristics
Operating system
Traveling device use hydraulic pilot control.
Crane system is controlled by two joysticks located to the right and left of the operator's seat.
Right joystick Forward - lowering the hook Backward - lifting the hook Right - turn the crane to the right Left - turn the crane to the left |
Left joystick Forward – boom extension Backward – boom retracting Right – lifting the boom Left - lowering the boom |
The pipe gripper is controlled from the control panel
The controller is responsible for the appropriate adjustment of the engine speed depending on the load.
Engine VOLVO TAD492VE
Main pump Rexroth (Germany)
Track chassis
Retractable, in working mode chassis is extended, in transport mode chassis is retracted. Minimum ground clearance is 900 mm.
Left and right floating box
Use welding structure to reduce weight under the condition of guaranteeing strength. Each floating box is divided into 5 separate waterproof compartments, which makes machine to be afloat, even if one of the compartments is flooded.
Drive chain
Heavy duty single pitch drive chain (pitch 152,4 mm)
Drive shaft
The drive shaft has three drive sprockets for simultaneous driving of three track chains. The drive sprockets are removable.
Running gear
The front and rear drive sprockets rotate simultaneously. This ensures sufficient driving force and protects the chain from slipping.
Pipegrippers
Pipegrippers open completely. The contact points of the gripper with the pipe are covered with rubber pads, which prevents slipping of the pipes and keeps the corrosion protection of the pipes from damage.
In the fully closed position the grippers are self-locking. The cylinder rod is not subjected to the reverse force of the pressing arm to prevent the pipe from moving and falling due to the walking vibration and other reasons.
Crane unit
Max. lifting torque moment is 600 KNM. The boom has three-section construction with wire rope.
When the crane arm is fully extended and the angle is 34.5 degrees, the crane arm can lift up to 8 tons of weight. Under these conditions, lifting torque moment is 600 KNM (if boom is fully extended (7.5 m) lifting capacity is 8 t).
Auxiliary winch
Single-rope, maximum pulling force is 20 t, maximum length of the cable is 200 m. Main functions: 1) self rescue 2) towing equipment and engineering materials.
Based on the customer requirements the multifunctional amphibious pipeline carrier can be equipped with the following functions:
Standard configuration includes 2 pipe gripper and crane unit.
Auxiliary winch, excavator unit, diesel generator, welding equipment can be set up optionally.
