9.4.1 Adjustable type Beam Clamps

An adjustable type beam clamp, as the name implies, is adjustable to fit beams of various size. Some, such as the type illustrated in Figure 9.4.1-1 a are self-adjusting whilst others, such as the type shown in Figure 9.4.1-1 b, require the operative to make the adjustment. In addition, there are some designs which, while not adjustable, will nevertheless accommodate beams of various size and may therefore be conveniently placed in this class, e.g. Figure 9.4.1-1 c.

Depending on the design, adjustable clamps are only capable to adjustment within specific limits and are therefore manufactured in a series of size ranges.
