Skidsteer: EZ Patcher

Specifications for EZ Patcher Mastic Skid Steer Attachment General A. This machine shall be the manufacturer's current production model manufactured in the United States of America. B. The machine will be capable of being filled with hot material from a Patcher II or Patcher 4 machine after preheating, which shall take less than 30 minutes. The machine shall also be capable of melting material blocks directly for small jobs; however, the heating/melting time may exceed 2 hours depending on number of blocks to be melted. C. A comprehensive safety manual and an operational/maintenance manual shall be supplied with each unit. D. Thermostatic control for the tank surface and material shall be provided and shall have sufficient sensitivity to maintain product temperature within the manufacturer’s specified application temperature range. E. Temperature indicating devices shall have intervals no greater than 5°F (2.8°C) and shall be calibrated as required to assure accuracy. F. The mixer shall have a continuous material mixing system to provide uniform viscosity and temperature of the material being applied. G. Power supply shall be provided by the Skid Steers 12Vdc power system. Required Safety Features A. The unit shall have a safety shut-off on the lid that automatically stops the agitator when the lid is opened. B. This unit shall have a safety release in place for the hydraulicly actuated gate to allow emergency manual closure of material gate in the event of hydraulic control failure. FRAME A. This machine shall be a skid steer attachment that can be attached from either side and provides fork truck tubes for transport purposes when not connected to a skid steer loader. -- 1 of 6 -- The frame shall include the features required to mate to the boom of typical skid steer loaders with the industry standard attachment system. B. This machine shall provide walkable lids and top with diamond treadplate. There shall be 2 lids to provide loading of material from either side of the machine. The lids shall include self-latching locks that cannot be removed and can be operated from either side of the machine. C. The primary structure of the machine shall be 2”x2” thick wall square tubing and steel sheet metal ranging from 10-gauge to 3/8” thick plate, all welded together. D. Shall be compatible with Skid Steers with a minimum Rated Operating Capacity of 2,550 lbs. (1,156.6 Kg) HEATING TANK A. The material heating tank shall be a V- shaped vessel with 7.5 inch (19 cm) radius at the bottom, 36 inch (91 cm) wide at the top, 13.5 inch (34 cm) deep, by 56.25 inches (143 cm) long having a capacity of 65 gallons (246 L) at ambient temperature. B. The tank will have a side discharge chute with a hydraulically actuated material gate that drops material into a floating material drag box assembly. C. The maximum filling height shall be 18 inches to allow the machine to be filled directly from a Patcher II or Patcher 4 machine. D. A tubular propane burner shall heat an air jacket under the material tank. A flame spreader shall be situated between the flame and the material tank to minimize direct flame contact to tank. E. Air baffles shall be provided to create the air jacket within which the burner operates and shall also provide protection against wind blowing out the flame. F. A bottom burner cover shall be provided to prevent ignition of flammable materials under the machine (such as grass) while also providing paths for combustion air as well as water drainage while not in use. -- 2 of 6 -- HYDRAULIC SYSTEM A. The hydraulic system shall be powered by the auxiliary hydraulic system of the skid steer loader through industry standard quick connect hydraulic fittings on the boom. B. Input flow shall be a minimum of 9 GPM and a maximum of 25 GPM. C. Mixer valve shall be solenoid operated by toggle switch located in switch pod of the in- cab control system. D. The control will allow for bi-directional operation of the mixer. A mix-melt mode that reverses automatically once a minute and a dispense mode that moves material towards the discharge gate shall be provided. The switch shall have a center “OFF” position for the mixer. E. The material gate shall be operated by a solenoid valve controlling a hydraulic cylinder to open/close the gate. The solenoid valve shall be operated by a by directional momentary toggle switch located in the switch pod of the in-cab control system. The toggle switch shall include a center stop position. A flow control valve will be mounted below the cab system storage case to adjust the speed of material gate opening and closing. F. The material gate shall include a manual release that allows the gate to be closed by hand in the event of a hydraulic control failure. HEATING SYSTEM A. The material tank is heated by a 76,000 BTU/hr propane burner at the bottom of the material tank. Burner shall run a minimum of 8.4 hours on a full 30gal tank of propane (worst case scenario continuous burn) B. The burner shall be a stainless-steel pipe configuration with flame holes down the length of both sides of the burner as well as flame holes at the end of the pipe cap to heat the material discharge chute area. C. The burner flame shall contact the stainless-steel flame spreader instead of the material tank directly. D. The burner exhaust gas shall be vented through the side air baffles and end caps through openings along the top edges of these panels -- 3 of 6 -- IGNITION OF BURNER A. The burner shall be lit by a constant duty high voltage transformer powering an electric spark igniter. B. This igniter shall work with a sensor that detects a lack of burn or ignition and shuts down the fuel supply. C. The thermostat control is located in the control box. TEMPERATURE CONTROL A. The mixer shall have a thermostatic control device that will automatically regulate tank and material temperature. B. The control shall have a digital readout for temperatures of tank and material. C. The thermostat shall…
