INTRODUCTION Autoquip Corporation has manufactured the FREIGHTLITE. It has been designed to move lightweight materials between multiple floors or levels safely and efficiently. It has been built to provide many years of dependable service. Proper installation of this equipment is vital to both the efficiency of the unit and the ultimate satisfaction of the end user.
INSPECTION & IDENTIFICATION The following items are typically shipped loose within each FREIGHTLITE order: A. B. C. D. E. F. G. H. I.
RESPONSIBILTY OF OWNERS/USERS CODE COMPLIANCE Ultimate responsibility for gaining state and local code approval is the responsibility of the buyer of the VRC. Please acquaint yourself with the permitting and/or licensing expenses and requirements of the local regulatory agencies in the installation area. .
SAFETY SIGNAL WORDS SAFETY ALERTS (Required Reading!) The following SAFETY ALERTS are intended to create awareness of owners, operators, and maintenance personnel of the potential safety hazards and the steps that must be taken to avoid accidents. These same alerts are inserted throughout this manual to identify specific hazards that may endanger uninformed personnel. Identification of every conceivable hazardous situation is impossible.
SAFETY PRACTICES DANGER! High voltage! May cause personal injury or death. Repairs should only be performed by a qualified service/control technician!! DANGER! Never go under a platform! To avoid personal injury or death, always be sure the load has been removed from the platform and that it has been blocked from underneath! See “Blocking Instructions” section.
SAFETY PRACTICES DANGER! Practice field safety procedures! To avoid personal injury or death, utilize all applicable precautions for steel erection and equipment assembly in addition to OSHA regulations for lock-out, tag-out, etc.! DANGER! Secure platform and cylinders! Do not remove or disconnect the power unit unless the platform and cylinders have been secured. See “Blocking Instructions” section.
SAFETY PRACTICES WARNING! Secure unit before making static inspections! Make sure the platform is fully lowered and the power is turned off (disconnected at the safety disconnect switch) before performing static inspections. Place signs at all gates, doors, controls, etc. indicating the system is temporarily out of service for routine maintenance per OSHA requirements for Lock-Out, TagOut.
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.
SAFETY PRACTICES CAUTION! Do not operate motor at relief pressure! The motor should not be operated for more than a few seconds when the unit is operating at relief pressure. Longer running times could result in damage to the pump. CAUTION! Automatic cylinder retraction possible! Be aware that the cylinder rod may retract into the cylinder body automatically when the hydraulic hose is disconnected.
SAFETY FEATURES There are several active safety features and devices to help protect personnel, property, and the equipment. ZERO DRIFT FEATURE A zero drift feature has been incorporated into the FREIGHTLITE lift. The zero drift uses a limit switch mounted at the upper level and the pressure switch circuit. The limit switch is tripped closed when the carriage is at the upper level. The electrical circuit is transferred to the pressure switch, if the pressure switch closes due to a pressure drop or leak.
SAFETY FEATURES SAFETY RELEASE BYPASS VALVE (SRBV) The SRBV is a part of the hydraulic system. Should the system pressure exceed the predetermined pressure setting, the SRBV will bypass the pump output back to the oil reservoir. The SRBV is factory set to the proper pressure, which will prevent damage to the mechanical, hydraulic, and electrical systems due to overloading, obstruction, or other circumstances. This setting should be tested once installation is complete (see Installation section).
SAFETY FEATURES SAFETY INTERLOCKS/LATCHES-GATES OR DOORS (where applicable) These are electro/mechanical devices that prevent operation of the FREIGHTLITE when the gates or doors are left open on any level. They also prevent the gates or doors from being opened at any level unless the platform carriage is in place at that floor level.
SAFETY FEATURES PERSONNEL GUARDS Depending on the application, one or more of the following personnel protection features is included in the design of this equipment (different states may vary on the exact design and orientation of these features – IT IS IMPORTANT TO BECOME FAMILIAR WHICH THE SPECIFIC CODE REQUIREMENTS OF YOUR STATE): - - GATES & ENCLOSURES: Required per ASME B20.1 to protect personnel from inadvertent physical contact with a moving lift & moving load at all lift landings.

Do not make modifications to the lift without authorization from the manufacturer! Unauthorized and unforeseen carriage, lift structure, drive base or support bracing attachments added in the field could create an unsafe operating condition which could result in severe personal injury or death.
BLOCKING INSTRUCTIONS WARNING ! Only authorized personnel should perform inspection or maintenance and service procedures. Unauthorized personnel attempting these procedures do so at the risk of personal injury or death. DANGER ! Failure to properly adhere to lift blocking procedures is to risk the sudden and uncontrolled descent of the lift during maintenance or inspection. A falling lift can cause severe injury or death. This procedure describes the only factory-approved method of working under a lift.
BLOCKING INSTRUCTIONS When the Lift Carriage Must be Raised 1. All loads must be removed from the lift platform prior to engaging the maintenance devices. These devices are designed to support an unloaded lift only. Failure to remove the load from the platform prior to blocking could cause the failure of the maintenance devices and allow the lift to fall unexpectedly. 2. Raise the carriage to the desired elevation.

TROUBLESHOOTING ANALYSIS DANGER! To avoid personal injury, NEVER go under the lift platform until it is securely blocked (See "Blocking Instructions" section) and the load is removed. Troubleshooting and maintenance on the lift should only be performed by qualified service technicians!! PROBLEM Unit will not raise (motor not running or “humming”). POSSIBLE CAUSE AND SOLUTION • The emergency stop button may be depressed or jammed. Check all push-button stations. Repair as necessary.
TROUBLESHOOTING ANALYSIS PROBLEM Unit does not raise (motor is running or humming) POSSIBLE CAUSE AND SOLUTION • The load may exceed the rating. Remove the excess load. • Check for hydraulic oil leak. Correct if needed. • Check for oil shortage in the reservoir and add oil, if necessary. • Rotation on the 3-hase motor may be reversed. Reverse any two motor electrical leads. • 3-Phase motor may be single-phasing (humming). Check wiring, fuses, etc. • Breather cap on the reservoir may be clogged.
TROUBLESHOOTING ANALYSIS PROBLEM Motor labors or heats excessively. Unit operates in a “spongy” or jerky fashion. Motor will not turn off when lift reaches fully raised position POSSIBLE CAUSE AND SOLUTION • The voltage may be low. Check at the motor terminals while the pump is running under load. Do not check at the line source or while the pump is idling. Inadequate wiring can starve the motor even when the source voltage is ample. • The wiring may be incorrect.
TROUBLESHOOTING ANALYSIS Unit won’t lower • The emergency stop button may be pressed or jammed Check and repair. • The gates or doors may be open. Close and try again. • Control transformer fuse may be blown. Check and replace. • Manually bleed off the hydraulic pressure with the lower valve. If the lift lowers, check the electrical circuit and the down solenoid. If the lift does not lower, see next section below.
TROUBLESHOOTING ANALYSIS Unit lowers too slowly with a load. Unit raises, then lowers back slowly. • Check for a pinched hose or tubing. • The down valve may be malfunctioning. Check and replace control valve. • The down valve solenoid mounting is loose preventing the valve from opening completely. Check and repair. • Oil is extremely heavy for the application or low temperature is causing a thickening of the oil (see Oil Recommendations in the General Maintenance section).
