SPECIFICATIONS 

 

Description: 

Designed for use with a crane or other hoisting equipment, P1-04DC lifters employ vacuum to 
hold a load for lifting, and they provide manual 180° rotation and manual 90° tilt movements 
for load manipulation.

Manual, 90°, with automatic locking in vertical position 

Vacuum Pump:

 

Diaphragm type, 1 SCFM [28 liters/minute] nominal airflow 

Vacuum Reserve Tank:

 

Vacuum reservoir helps prevent immediate vacuum loss in case of power failure and extends 
battery life by reducing pump cycles required to maintain vacuum. 

Vacuum Gauge:

 

Dial gauge indicates current vacuum level in positive inches of Hg and negative kPa. 

Low Vacuum Warning 

Light:

 

Red light is energized until vacuum level is sufficient to lift maximum load weight (higher than 
16" Hg [-54 kPa]) and whenever vacuum loss causes pump to re-engage. 

Low Vacuum Warning 

Buzzer (if applicable): 

Maximum Alarm Volume = 103 dBA at 2 ft [60 cm].  While lifter is powered up, audible alarm 
warns the operator whenever vacuum is not sufficient for lifting the maximum load weight. 

Options:

 

See separate instructions about optional features. 

Operating Elevation:

 

Maximum = 6000 feet [1828 meters] 

Operating Temperatures:

  32° to 104° F [0° to 40° C] 

Service Life: 

This lifter is designed to have a service life of at least 20,000 lifting cycles, when used and 
maintained as intended.  Vacuum pads, filter elements and other wear-out items are 

excluded; see MAINTENANCE and REPLACEMENT PARTS LIST for more information.  For the
