FND-TSG500
1. 500L large melting tank: less refilling downtime & higher jobsite efficiency Compared with mainstream 200-350L small-tank models, it greatly cuts frequent material-refilling stops. Continuous non-stop sealing is available for long highway sections. Less start-stop waiting extends effective daily working distance and lowers machine shift cost.
2. Dual digital multi-zone temperature control + sealant recirculation heating: cut material waste & save sealant cost Real-time independent monitoring for thermal-oil, sealant and hose temperature prevents sealant carbonization from overheating. Recirculation heating speeds-up melting progress. Avoid wasted sealant caused by mis-controlled temperature and reduce consumable procurement expense.
3. External discharge pump: lower maintenance cost & minimize work-zone downtime loss Different from submerged pump solutions, on-site repair or replacement can be done without draining hot sealant inside tank. It shortens breakdown downtime and reduces project delay risk.
4. 6-meter long anti-kink electric heating hose: bigger working radius & save labor cost 78% larger effective working range than standard 4.5-meter hoses. Operators do not need to reposition the main unit frequently. Single operator can cover more work area, reduce labor intensity and cut on-site manpower input.
5. Low-height filling port: safer & faster feeding for higher site productivity Low-position feeding opening eliminates high-altitude feeding. Reduce safety risks and speed-up material loading, shortening construction cycle for each crack section.
1. All-in-one routing & sealing unit: save extra equipment investment cost The crack router is mounted on machine chassis and can be quickly lifted / detached by winch. No separate standalone router purchase required. All working procedures can be finished with one trailer haul, cutting project capital expenditure.
2. Adjustable routing width: one machine handles both municipal fine cracks & highway structural cracks Flexible routing width setting adapts to hairline cracks in city roads as well as deep wide structural cracks on expressways. One unit fits multiple project scenarios and improves equipment reuse rate.
3. Standardized crack pre-treatment: better finished quality & reduce re-work cost Router removes loose asphalt and debris inside cracks to ensure strong bonding between hot sealant and pavement. Greatly lower re-opening risk of repaired cracks, cutting re-pair expense within project warranty period.
1. Compatible with Crash-Truck crash attenuator complying with European-American safety standards. It absorbs impact energy during live-lane highway maintenance to protect operators and machine. Mitigate accident risk, prevent project shutdown or compensation losses, and meet safety access requirements for overseas highway projects.

Pre-operation InspectionCheck the equipment appearance, fuel level, heat conduction oil volume, hose integrity, electrical circuit and generator status to ensure all parts work normally.
Pavement Crack TreatmentUse a routing cutter to groove the pavement cracks, remove loose concrete and impurities on both sides of cracks to form regular grooves for sealing.
Crack Cleaning & DryingBlow out dust, debris and moisture inside the grooves with an air blower. The crack surface must be dry and clean before filling.
Preheat the Machine & Melt SealantTurn on the burner and automatic constant temperature control system. Put hot-pour crack sealant into the material tank, heat and melt the sealant for about 45 minutes until it reaches the working temperature.
Start Material Feeding & Crack SealingSwitch on the material pump. Guide the electric heating hose nozzle into the crack groove, continuously inject molten sealant into the groove evenly. Keep the sealant filling full and flat.
On-site Cooling & CuringAfter filling one section, let the sealant cool and solidify naturally. Do not allow vehicles or pedestrians pass before full curing.
Post-operation Cleaning & ShutdownStop feeding material, keep heating the hose for a short while to drain residual sealant. Shut down the burner and generator, clean the whole machine and store it properly.
