Specifications of LLRD-G120 crack sealing machine

LLRD-G120 Hand push or Traction type dual-purposed road crack sealing machine is a kind of small maintenance equipment used for repairing irregular cracks of asphalt pavement and road cement. It is simple and convenient in operation, and having convenient movement.



Domestic branded generator or other generator as customers’ needs.

Rated Power: 2.0 kw 

Voltage: 220 v


Hot melt kettle uses thermal oil heating which has uniform heating and sealant is not easy to carbide in the kettle.


Temperature monitoring system, LED digital display temperature control system, can monitor and adjust the temperature of the heat conduction oil and the temperature of the electric heating tube. 


The heating system of Italian imported Riello diesel burner can not only provide the ideal heating effect, it’s also stable and sustainable. through the use of advanced microcomputer control technology, the switch on and switch off function of the burner can be achieved automatically through setting heating temperature on the control panel. Through this, you could not only save energy consumption, but could also realize the real intelligence operations.

External type material pump: greatly simplifies the equipment maintenance procedures and improves the service life of the machine.


Electric heating tube: 4 m in length, can rotate 360 degrees. Applying the electric heating tube could smooth the process of glue pushing. The electric heating tube uses plastic Teflon as inner core, the outside of inner core is winded by heating wire, to ensure the maximum stretch and the highest heat transfer. It has multi-layer insulation; Outer is asbestos and heat pipe is yellow.


Humanized sealing spout scraper, is more efficient in operation, reduce the labor intensity of workers, and is equipped with a drip discharge valve, completely eradicate the road pollution.

Advantages and Features:




Imported diesel burner


Convenient in movement: Hand push or Traction type dual-purposed


Electric heating tube is 4 m in length, can rotate 360 degrees.


You could choose hand push or self-propelling during construction process as need. It could save labor cost and reduce using cost as well


Heat conduction oil indirectly heats the joint sealant, material pulling is controlled through infinitely adjustable-speed motor


Could seal various kinds of road cracks (asphalt road, cement road, etc.)


Could customize heat melting kettle


You could choose to equip the sealing gun with night-working lights.


1.Small volume and light weight makes it move easily. You could choose hand push or self-propelling during construction process as need, which brings great benefit to efficient construction. Irrigation of sealant is evenly and efficient.

2. Heat conduction oil indirectly heats the joint sealant, effectively prevent high temperature carbonization of the crack seal material 

3. Equipped with imported Italy Riello diesel burner; heating is more efficient.

4. The use of advanced control instrument, can clearly display and adjust the temperature of electric heating tube and heat conduction oil. The operator is clear about the operation of the machine at a glance.

5. The electric heating hose can rotate 360 degrees, and in use process need no clean-up.

6. Discharge pump is controlled through infinitely adjustable-speed motor, can regulate the flow of sealant according to need.
