Crack sealing machines are specially used for sealing the cracks on asphalt pavement of the expressways, highways, city road, airports,etc after roads' opening and maintenance. Sealing by the seal glue to ensure the whole usability and prolong the service work time of highway.
 
2. Parameter:
1) Net Weight: 2200kg
2) Material Melting Speed: About 40 mins
3) Hot melt kettle volume: 350L
4) Heat transfer oil / conduction oil: 120L
5) Engine: Imported Honda GX690 gasoline engine
6) Engine Power: 25hp
7) Fuel Tank: 50L
8)Hydraulic fuel tank capacity: 50L
9) Burner: Imported Italian Riello Diesel Burner
10)Burning Power: 100000 kcal
11) Heating Method: heat transfer oil indirect heating, to ensure that material will not be carbonized
12) Two stage melting: under the working status, we could use the cycling heating system to fill the material from upper material box and therefore form a cycle, heating sealant thoroughly; at the same time, it's equipped with vertical mixer, hydraulic driving and reversing, to ensure the material temperature balance in the hot melt kettle
13) Temperature control: monitoring the temperature of thermal oil filling, sealing materials and electric heating tube, the computer automatic control (when reaching the construction temperature, it would automatically conduct heat preservation procedure)
14) Temperature control scope: 0~299ºC
15) Feeding mechanism: the integration of discharging control switch; Infinite speed control; Equipped with a leak-proof switch
16) Feeding hose: The electric heating tube is 6M in length, can rotate 360°, with technology in spout incubator, avoid blocking pipe problem caused by low temperature
17) Discharging control: the infinite speed regulation control
18) Plate and lifting device: grooving machine, dryer equipment can be integrated in the back of sealing machine (optional), not hanging, equipped with plate and electric hoist to assist lifting up and down
19) Moving Method: Dual-purpose: hand-push type or traction type as you like
20) Vehicle suspension: leverage spring compression type of shock absorber
21) Self-propelling Speed: 10km/h

3.FEATURES:
1) The imported Honda GX690 gasoline generators: provide sufficient power system to the equipment 3)Hot melt pot adopts the design of inter-layered heat conduction oil. It can use special-purposed heating sealing glue, it can also use modified asphalt after heating.
4) The discharge hose adopts electric heating during the whole heating process, in addition to the automatic discharging switch, it's specially equipped with a drip-proof valve, thus completely eradicating waste and pollution of road surface material caused by material drip

5) The bracket of spear parts of Crack sealing gun adopt design of heat insulation box, which are interlinked with hot melt kettle. Even when stopping work, you also need not worry that spear sealant would cause coagulation block. The crack sealing gun uses Teflon technology in the heating pipe, guaranteeing no bond in the barrel after use, therefore, there is no additional cleaning procedures of the pipeline

6) Digital display: Through microcomputer control, you can respectively control the temperature of hot melt kettle, conductive thermal oil and crack sealing gun, thus achieving accurate control of heating temperature for different seal material7) The whole machine adopts fully enclosed design, not only having beautiful shape, but also can better protect the engine and other key components
