A boom apparatus is provided for a fork truck having an elevator frame, a carriage movable via the elevator frame, and fork-supporting transverse members on the carriage. The apparatus includes a boom mount mechanically attached to the transverse members, and a boom mechanically attached to the boom mount. The boom mount includes a vertical plate, and top and bottom braces forming opposing hooks for engaging the transverse members. The top brace also includes a narrow section with horizontal hole that aligns with holes in brackets on the boom. A lock pin extends through the aligned holes to lock the boom to the mount. The mount includes a bottom T pin that fits into a slot at the boom's bottom to secure the boom in a vertical orientation on the mount. By this arrangement, the boom and boom mount can be securely and easily attached to a fork truck without welding.
