Blocking and Bracing of IPE

TM 38-260

convert the type 3 load into either a type I or a type 2 load. Blocking and bracing is sometimes used in connection with

type 2 loads. In the case of type 3 loads, it is almost an unavoidable operation due to the irregular shape, fragility,

heaviness, or high density of accessories or tooling which make up such loads. Cushioning is applied to the three types

of loads. In the case of type 1, it is used primarily to prevent surface abrasion. In the case of type 2, to prevent surface

abrasion and to absorb part of the impact shock. In the case of type 3 loads, it is used to prevent contact of the items

with each other and/or with the faces of the container, and to absorb shocks, jolts, and vibrations.

(7) Lack of/or availability of mounting provisions. It is often possible to secure an accessory or tooling, to the

basic item, to a skid platform, or within a container using integral mounting devices. Many items of IPE, accessories, or

tooling may not have adequate mounting devices. Appropriate alternate methods, such as tie-rods, yoke assemblies, and

J-bolts, which will protect the equipment must be selected.

8-5. Blocking and Bracing of IPE

a. General. Internal blocking and bracing are used to rigidly secure and support movable and over hanging

components to substantial elements of the equipment by means of wood blocks and other mechanical devices.

(1) The purpose of internal blocking and bracing is to prevent distortion or breakage of components while in

transit. Internal blocking and bracing must make contact only with solid or substantial parts of the equipment. Do not

block or brace a machine component to the skid platform.

(2) Skidding, including the attachment of the machine to the skid, and external blocking and bracing, or the

attachment of the skidded machine to the transporting vehicle are covered in paragraphs 8-8 through 8-12.

(3) Failure to block and brace movable parts and fixed components with fragile mountings results in greater

damage to shipments of IPE than any other factor.

(4) Many metalworking machines and grinders, may have tables, grinding heads, and/or other heavy components

that are supported or moved on ball or roller type bearings.

(a) Special attention should be paid in these cases to preparation for shipment.

(b) Blocking to prevent movement shall be properly designed and installed.

generate flat spots on the bearings or dents in the load bearing member. Damage of this nature is costly and time

consuming to repair.
