  • Page 10 WARNING Velocity fuse lock-up requires factory help! Contact your local FREIGHTLIFT representative or call Autoquip Service Department if hydraulic velocity fuses should lock up! WARNING! Do not weld on the guide flanges of the masts! Interfering with the free travel of the wheel guides could cause permanent damage to the lift and prevent safety devices from operating as intended.
  • Page 11 SAFETY PRACTICES WARNING The velocity fuse (VF) must be properly installed! The VF is attached to the elbow fitting in the rod port of the cylinder. If the VF is installed improperly, it will not lock the carriage in place in the event of a catastrophic hydraulic line break! WARNING Do not over travel! Mechanical stops must be in place to prevent the...
  • Page 12 SAFETY PRACTICES CAUTION! The hydraulic cylinder-retaining strap must be in place! A secure strap will prevent the cylinder from falling after the cable is removed! NOTICE Purge air in the system! The presence of air in the system can lead to a lock-up of the velocity fuses.
  • Page 13 SAFETY PRACTICES NOTICE Protect cylinder rods, hydraulic ports and lines at all times! Welding splatter and dust from grinding operations can cause severe damage to this equipment. NOTICE Do not damage the pump or motor! If the motor needs to run during the installation process and the electrical work is not complete, only do so for a second or two after the mechanical stop is pressed.

  • Page 14: Safety Features

    Slack ropes require factory help! Do not attempt to repair slack wire rope conditions alone! Always contact the local representative or call the Autoquip Service Department. ZERO DRIFT FEATURE A zero drift feature has been incorporated into the hydraulic FREIGHTLIFT. The zero drift utilizes a pressure switch in the electrical circuit.
  • Page 15 SAFETY FEATURES HYDRAULIC VELOCITY FUSES Each hydraulic cylinder has a hydraulic velocity fuse (HVF) installed in the cylinder ports. These HVFs are installed in the predetermined hydraulic oil flow velocity as the oil returns to the reservoir. Should a catastrophic rupture or breach occur in the hydraulic system and oil flows through the breach that exceeds the HVF rating, the HVF will trigger and lock up.
  • Page 16 SAFETY FEATURES CONTROL TRANSFORMER SECONDARY FUSE This fuse is attached to the electrical control transformer and protects the 115 volt control circuit from damage should a fault occur which would result in excessive electric current flow. Should the fuse activate (blow), it will prevent the operation in either direction and the interlock circuit will not operate.

  • Page 69: Operating Instructions

    OPERATING INSTRUCTIONS 2. The rotating motor shaft is mechanically coupled to a positive displacement gear pump. The pump will rotate, drawing oil from the reservoir, pressurizing it, causing flow through the check valve, and out to the cylinders through high pressure hoses. The incoming volume of oil flows to the rod side of the cylinder pistons, causing the rods to retract into the cylinders.

Because Autoquip "Super-Torque" motors actually deliver substantially more horsepower than their nameplate rating, they must always be wired for heavier current-draw than standard motors of the same nameplate rating. However, because of the "Super-Torque" motor’s starting efficiency and superior running characteristics, circuit components do not have to be as large as for standard motors of equal delivered horsepower.
