Model Number: VL411LDC Description: Designed for use with a crane or other hoisting equipment, the VL411LDC lifter employs vacuum to hold a load for lifting in the upright orientation. Power Source: 12 volts DC, 10 amps (with Thomas pump) or 3.5 amps (with Dynaflo pump)
Wood’s Powr- Grip cannot be responsible for the safety of a lifter that has been modified by others. For consultation, contact Wood's Powr-Grip (see LIMITED WARRANTY). Rev 19.3/9-18 VL411LDC: #35162...
OPERATING FEATURES Note: Components featured in the following instructions for assembling, operating or maintaining the vacuum lifter are underlined on their first appearance in each section. Standard VL411LDC shown. 1 LIFT SLING 6 Enclosure with VACUUM PUMP, 11 CONTROL HANDLES...
3) Connect the electrical connectors uniting the battery to the battery charger and the vacuum generating system. The lifter is now operational. 4) Perform Operational and Load Tests for the lifter as directed in MAINTENANCE: T ESTING CHEDULE Rev 19.3/9-18 VL411LDC: #35162...
Lifters that feature concave vacuum pads can also attach to some kinds of curved loads. Since curvature affects the lifting capacity, contact Wood’s Powr-Grip for help in determining the Maximum Load Capacity for a particular curved load. Rev 19.3/9-18 VL411LDC: #35162...
After the vacuum lifter has reached the end of its service life, you must dispose of the lifter in compliance with all local codes and regulatory standards that are relevant for the geographical region. Note: This lifter is equipped with a battery, which may be subject to special disposal regulations. Rev 19.3/9-18 VL411LDC: #35162...
Although initially it may be difficult to apply the pad to a load, this condition should correct itself with continued use. Consult CE Standard EN 457 for alternative ways to determine whether the alarm is clearly audible to operators. Rev 19.3/9-18 VL411LDC: #35162...
Certain load materials are too rough or porous to allow the lifter to form a seal which can be maintained for 5 minutes without power. However, in geographical locations where CE Standards do not apply, it may be possible to use the lifter to lift such loads. Contact Wood’s Powr-Grip for more information. Rev 19.3/9-18 VL411LDC: #35162...
WARNING: Never attempt to lift load while alarm is sounding. Do not attempt to lift the load while the alarm is sounding; such an attempt could result in a load release and possible injury to the operator. Rev 19.3/9-18 VL411LDC: #35162...
Then push the valve handle inward to the “release” ( ) position (power off), as shown. Do not attempt to move the lifter until the vacuum pads TO RELEASE disengage completely from the load. Rev 19.3/9-18 VL411LDC: #35162...
Preferred temperatures for storing the battery are 32° to 70° Fahrenheit [0° to 21° Celsius]. Higher temperatures require the battery to be charged more frequently. Storage at temperatures above 100° Fahrenheit [38° Celsius] should be avoided. Rev 19.3/9-18 VL411LDC: #35162...
CAUTION: Be sure to use appropriate cleaning methods for each type of electrical component, as specified by codes and standards. Improper cleaning can damage components. Rev 19.3/9-18 VL411LDC: #35162...
V discussion for inspection, testing and adjustment ACUUM WITCH DJUSTMENT procedures. ASME Standard B30.20 requires the lifter to be tested to 125% of its Load Capacity. Flat Lifters are exempt from this requirement. Rev 19.3/9-18 VL411LDC: #35162...
The battery charger must be disconnected from its AC power source in order to test the battery energy; otherwise, the energy reading on the battery gauge would not be accurate. Rev 19.3/9-18 VL411LDC: #35162...
The charger is designed to automatically sense the energy level of the battery and reduce the charging rate when the battery is fully charged. Accordingly, the charger does not need to be unplugged until the lifter is going to be used again. Rev 19.3/9-18 VL411LDC: #35162...
If the lifter is equipped with VPFS10T or VPFS625 pads, the sealing edge is the replaceable sealing ring. When it is damaged, install a new sealing ring insert. In such cases, see T to follow. EPLACE EALING NSERT IN ACUUM Rev 19.3/9-18 VL411LDC: #35162...
If these cleaning methods are not successful, contact Wood’s Powr-Grip or an authorized dealer for assistance. Any test material used must be fully and independently supported, and capable of bearing the lifter’s weight. Do not use the lifter to lift the test material during the vacuum test. Rev 19.3/9-18 VL411LDC: #35162...
The filter element kit may contain two sizes of bowl seals (O-ring type gaskets). If so, use the smaller bowl seal; or if in doubt, compare the old bowl seal to determine the appropriate size. Rev 19.3/9-18 VL411LDC: #35162...
Depending on the product, the head assembly (3) may be rotated to an orientation different from the one shown. When removing the head assembly, always take note of its orientation and install it the same way during reassembly. Make sure that the intake and exhaust ports remain in their original positions. Rev 19.3/9-18 VL411LDC: #35162...
When removing the valve plate, always take note of its orientation in the pump head (2), and install the valve plate the same way during reassembly. In all cases, the valve plate must be oriented so that its intake hole is matched with the head port that connects to the check valve. Rev 19.3/9-18 VL411LDC: #35162...
In order to observe lifter functions while vacuum is decreasing, it may be necessary to create a controlled leak in the vacuum system (eg, by breaking the seal between one or more vacuum pads and the test surface). Rev 19.3/9-18 VL411LDC: #35162...
When the vacuum switch is adjusted correctly, the vacuum pump turns off only vacuum increases to a level higher than the minimum lifting level; and the pump turns on again before vacuum decreases to a level lower than the minimum lifting level. Rev 19.3/9-18 VL411LDC: #35162...
