Installation & Commissioning
3.2.2 Lift Cylinder Hydraulic Connection
Inspect the hydraulic hose before connection, ensuring the line is free of ruptures, cracks, cuts, or other damage.
Inspect the female quick-connect fitting to ensure it is free from damage. Connect the female quick-connect on
the lift cylinder hydraulic hose to the male quick-connect fitting attached to the needle valve on the tong valve
bank. Once the fitting has snapped into place give the hydraulic line a light tug upwards to ensure the fitting is
securely seated.
If not already done, connect the main hydraulic supply to the power tong (see sub-section 3.3.2 for proper
hydraulic connection procedure). Energize the hydraulic supply to the power tong.
Lift the power tong approximately three inches off the work surface, and suspend the tong for approximately thirty
seconds. Following the suspension alternately lift and lower the tong slightly to confirm that lift and lower functions
each operate correctly.
3.2.3 Lift Cylinder Safety
!
WARNING
A CLEARLY IDENTIFIED REMOTE POWER PACK EMERGENCY STOP MUST BE INSTALLED IN THE
IMMEDIATE VICINITY OF THE TONG OPERATOR.
McCoy Global recommends following an industry-accepted standard such as OSHA, ASME B30.9-2006, or
manufacturer’s guidelines when performing any rigging and overhead lifting. Use by untrained persons is
hazardous. Improper use may result in serious injury or death. Do not exceed rated capacity.
Working Load Limit (WLL) is the maximum allowable load in pounds or kilograms which may be applied to the
load-bearing device, when the device is new or in “as new” condition, and when the load is uniformly and directly
applied. The WLL must never be exceeded.
The Working Load Limit or Design factor may be affected by wear, misuse, overloading, corrosion, deformation,
intentional alterations, sharp corner cutting action and other use conditions.
See OSHA Regulation for Slings 1910.184, ANSI/ASME B30.9-”SLINGS”, ANSI/ASME B30.10-”HOOKS” and
ANSI/AMSE B30.26 “RIGGING HARDWARE” for additional information.
The flexible line providing hydraulic power to the lift cylinder has been equipped with abrasion-resistant, high
visibility protective wrap. The high visibility wrap allows operators to easily see monitor the position of the hydraulic
line at all times, and can easily see if the line appears to become entangled or snagged.
