Insert the top hoist mounts into the hoist frame in the same way in which they were shipped. Set the lower arm of the scissor assembly parallel to the truck frame. This can be done using a jack stand
8. Using hard wood boards that are one inch thick and the same width as the frame, cover the bottom of the bed long members where the long members will rest on the truck frame when fully lowered
Drill and bolt the boards in place with carriage bolts that are recessed into the wood. By doing this the weight of the bed and the load is distributed across the length of the truck frame and is not concentrated on a few points. On completed installations there should be a gap between the upper and lower mounts from the use of the wood spacer. This is acceptable, because it distributes the load over the full length of the truck frame, preventing a concentrated load at the mounting point.
9. Lower the truck bed onto the truck frame, positioning it exactly as it will be mounted when lowered. Weld the vertical plate assembly of the tail hinge to the long member of the bed with the pin inserted in the tail hinge assembly . Insure that the vertical plate assemblies are installed correctly as shown. It may be necessary to install some washers as spacers between the pin bushings and the vertical plates to help center the body and keep it from moving from side to side.
10. There are two methods to attach the upper hoist mount to the bed long member. One method is to bolt the upper mount to the long member. The other method is to weld the upper mount to the long member. Both methods require a 1/4 inch diagonal plate installed to the long member, centered on the upper mount location This will prevent the long member from rolling under. This plate is furnished by the installer due to the variety of long member sizes.
A. For bolt-on applications a stringer plate must be welded to the upper mount. This allows the upper mount to be bolted to the long member. Drill and bolt the stringer attachment plate to the long member. It may be necessary to raise the bed to complete bolting the upper mount.
B. For applications in which the upper mount is welded, it can be welded in place as shown in Figure 14.

插入顶面卷扬机登上入卷扬机框架相似在哪些他们运输了。 设置scissor 汇编的更低的胳膊平行与卡车框架。 这可能做使用起重器立场
8. 使用和框架一样是一英寸厚实的和宽度的坚硬木板, 报道长的成员将基于卡车框架床长的成员的底部何时充分地降下
操练和闩上委员会到位以被隐藏入木头的支架螺栓。 被做这床和装载的重量被分布横跨卡车框架的长度和不被集中几点。 在完整设施那里应该是一个空白在上部之间和更低登上从对木间隔号的用途。 这是可接受的, 因为它分布装载在卡车框架的充分的长度, 防止被集中的装载在架置点。
9. 降低卡车床卡车框架, 确切地安置它因为它将登上何时降下。 焊接尾巴铰链的垂直的板材汇编对床的长的成员与别针被插入在尾巴铰链汇编。 保险, 垂直的板材汇编正确地被安装依照被显示。 它也许是必要安装一些洗衣机作为间隔号在别针轴衬和垂直板材之间帮助中心身体和保留它从行动从一边到另一边。
10. 有二个方法附有上部卷扬机登上床长的成员。 一个方法将闩上上部登上对长的成员。 另一方法将焊接上部登上对长的成员。 两个方法要求一块1/4 英寸对角板材被安装对长的成员, 围绕在上部登上地点这将防止长的成员滚动下。 这块板材由安置者装备由于长的成员大小品种。
A 。 为伯勒屯应用纵梁板材必须被焊接对上部登上。 这允许上部登上被闩上对长的成员。 操练和闩上纵梁附件板材对长的成员。 它也许是必要培养床完成闩上上部登上。
B 。 为上部登上被焊接的应用, 它可能被焊接到位依照被显示在上图14
佩服，这也有人问，更有人答！！！
