Contractors must consider factors such as allowable driving stresses, desired penetration rates and other data as defined by project specifications. For other sites, several types of hammers may be suitable. On some construction sites, only one type of hammer may be viable for the specific pile-soil combination. Selecting a hammer may be the most crucial aspect of pile installation. Each component of the drive system can impact both the performance of the hammer as well as how it transfers its energy to a pile. The driving systems used to raise and lower hammers consist of four components: the lead, the hammer cushion, the helmet, and the pile cushion. Field inspections can be performed to make sure that the hammer conforms to minimal standards, and record observations on the hammer and driving system performance. The way that the hammer interacts with the pile-soil system can be modeled before driving and then monitored during installation to both control driving stresses and estimate load capacity. Not only do they advance the pile into the ground, but they serve as testing equipment in measuring the pile’s bearing capacity. Hammers play a crucial role in pile installation. From rams that were raised by humans or horses to steam, air, and hydraulic hammers to double acting hammers, this equipment is an essential part of any construction project where piles are necessary. Over time, the technology for pile installation has led to the development of hammers that are both larger and faster. ![]()
