If the pile hammer is to be stored or out of service for an extended period of time, certain precautions should be taken to prevent damage to the hammer and risk to personnel.
A storage or resting place should be selected which will adequately support the weight of the hammer. The site should be level, firm, and a protected area. Keep the hammer off the ground. This can be done by using the original shipping skid or resting the hammer on two 8″ x 8″ wood beams. In addition, because of the hammer’s great weight it should be secured to preclude damage from unexpected movement. The ram should be properly blocked in the down position. This is accomplished by using a 4″ x 4″ timber wedged between the cylinder and the ram and securing the timber to a column with banding iron. The 4″ x 4″‘s should be used on diagonally opposite columns.
After its use, a thorough inspection should be performed. If any defects are found, they can be repaired during the storage period,thus preventing malfunction, danger or on the job downtime.
Before storage, a complete lubrication and rust proofing should be done in order to protect the hammer from the elements and subsfequent corrosion. For further protection, a cover of canvas or plastic can be used to provide shelter, and thus reduce the effects of exposure to the environment.
When the storage period has ended and it is time to put the machine back into service, another thorough inspection, cleaning and lubrication will assure that the hammer is ready for service.
By taking these few precautions, the life of the hammer can be extended, its efficiency can be maintained, and its safety greatly enhanced. Detailed instructions on preparation for storage including inspection procedures and lubrication requirements are given in the Field Service Manual, supplied with each hammer by Vulcan.
