If your Stellar Labs Construction Equipment crane isn't operating, first ensure the parking brake is engaged. Also, verify that the radio receiver is receiving electrical power. If there's no power, trace back to the source, checking for blown fuses or loose ground connections. Finally, confirm the transmitter batteries are fully charged.
What to do if Stellar Labs Construction Equipment crane operates manually but not by radio remote?
If your Stellar Labs Construction Equipment crane operates manually but not via radio remote, start by checking for electrical power to the radio receiver. If there's no power, trace back to the source, looking for blown fuses or loose ground connections. Next, ensure the parking brake is engaged and that the parking brake switch functions correctly. You can test the switch with a continuity test; replace it if defective.
Why does stellar labs EC Construction Equipment crane operate slowly?
If your Stellar Labs Construction Equipment crane operates slowly, check the hydraulic fluid level in the reservoir and add fluid if needed. Also, check the hydraulic fluid temperature.
How to fix Stellar Labs Construction Equipment crane functions not operating via radio remote?
If not all functions of your Stellar Labs Construction Equipment crane operate via the radio remote, or if the crane operates intermittently, ensure the toggle switch on the transmitter is working correctly; replace it if defective. Also, check for power going to the valve bank coil solenoid of the non-operating function. If there's no power, inspect wiring connections on the wire harness plug connector for broken wires, loose connections, or poor crimps. If power is present, the solenoid valve may be blocked. Remove the stem valve, thoroughly clean, lubricate, and reinstall it, being careful not to overtighten. Replace the valve if it won't close.
What causes cylinder drift in Stellar Labs Construction Equipment?
If the cylinder in your Stellar Labs Construction Equipment drifts outward or downward, first check for air in the hydraulic system by operating all cylinders. Start with the extension cylinder, then the main boom, winch, rotation, and hydraulic stabilizers (if installed). Extend each cylinder halfway, retract fully, and then extend to the end of its stroke, repeating 2-3 times slowly. Also, ensure the holding valves are operating correctly by removing, cleaning, and inspecting them after relieving hydraulic pressure. Check the cylinder rod for scratches, and replace the rod or cylinder if scratches are found. Finally, inspect the piston seals for damage and install a new cylinder seal kit if needed.
Why are two functions operating at the same time on stellar labs EC Construction Equipment?
If two functions of your Stellar Labs Construction Equipment operate simultaneously when only one is toggled, first ensure all solenoid valves are latched in the center position. Then, identify the function operating on its own and check for power going to its solenoid valve when it shouldn't be operating. If voltage is present, the toggle switch has likely failed and is stuck 'on'. If no voltage is present, the solenoid valve may be partially open. Remove the stem valve, thoroughly clean, lubricate, and reinstall it, being careful not to overtighten. Replace the valve if it doesn't close.
What to do if Winch 'Up', Main Cylinder 'Down', and Extension Cylinder 'Out' don't operate on stellar labs EC?
If the Winch 'Up', Main Cylinder 'Down', and Extension Cylinder 'Out' are the only functions not operating on your Stellar Labs Construction Equipment, first ensure the anti-two block limit switch on the boom end is properly adjusted. Next, test the limit switch by disconnecting and tying together the two wires connected to it; replace the switch if all functions then operate. Finally, inspect the cord for the cord reel for damage and check its continuity. Disconnect the cord reel from the crane harness and bypass the harness connection; replace the cord reel if the crane then operates properly.
How to troubleshoot a Stellar Labs Construction Equipment winch that will not lift load?
If the winch on your Stellar Labs Construction Equipment won't lift a load, ensure the object's weight doesn't exceed the winch's rated capacity. If the object is within capacity, try repositioning the truck and lifting without using the crane boom extensions.

This document is the owner's manual for the Stellar EC Series Crane, providing comprehensive information on its operation, maintenance, and troubleshooting. The Stellar EC Series Cranes are designed for safe and dependable service across various operations, emphasizing the importance of proper use and maintenance for peak performance and longevity.
The Stellar EC Series Crane is a telescopic crane designed for lifting and positioning loads. It is operated via a radio remote control, allowing for precise and simultaneous control of multiple functions. The crane is intended for use in various job site applications, requiring the operator to have a firm understanding of safety practices and the equipment's capabilities. Key operational steps include disengaging the drive axle, setting the parking brake, turning on crane power, positioning stabilizers, operating the crane (including unstowing, lifting, moving, and stowing), and finally, stowing the stabilizers and releasing the parking brake.
The manual covers models EC2000, EC3200, EC4000, EC5000, and EC6000. While specific load capacities are not detailed in the provided pages, the manual repeatedly stresses the importance of adhering to manufacturer's load charts and ratings, which are based on the machine's hydraulic, mechanical, and structural design, as well as stability. The crane utilizes a hydraulic system, and specific hydraulic oil recommendations are provided based on ambient temperature: High VI, low pour, ISO 22, AW hydraulic oil for below -5°F; High VI, low pour, ISO 32, AW hydraulic oil for -5°F to 90°F; and ISO 46, AW hydraulic oil for above 90°F. The rotation gear bearing tilt test specifies a maximum dial indicator change of 0.060” (1.524 mm) for Stellar Models EC3200-EC6000. Backlash specifications for the worm gear are 0.005” (0.127 mm) total indicator movement, with a recheck range of 0.005" to 0.012” (0.127 to 0.3048 mm). Torque data for various bolt sizes (5/16-18 to 1 1/2-6) and grades (Grade 5, 8, and 9) are provided in foot-pounds for both plain and plated bolts.
The crane features a radio remote control with an emergency stop button for immediate cessation of crane functionality. The remote control enters sleep mode after 15 seconds of inactivity and can be re-linked by activating a toggle switch. Battery replacement for the handheld transmitter uses AA Alkaline batteries. A backup cord is provided for manual operation if the radio function is unusable, connecting the transmitter handle to the control receiver on the crane mast. The remote control functions include Boom Up/Down, Extension In/Out, Winch Up/Down, and Rotate Clockwise/Counterclockwise. The manual emphasizes maintaining safe clearance from high voltage power lines, using wheel chocks on slopes, and ensuring stabilizers are positioned on stable, flat ground. It also warns against lifting personnel, exceeding load charts, and leaving loads suspended or unattended.
The manual outlines a basic crane maintenance schedule, including daily checks for hydraulic reservoir oil level, weekly greasing of rotation gear inner race bearings, monthly greasing of rotation gear worm drive bearings, quarterly greasing of open gear teeth, cylinder pivot points, and lubricating extension booms.
