IN view of the large numbers of ex W.D. lorries which are employed in this -country, the Shard tipping gear is of particular interest, as it is designed to convert any such vehicles' into end-tipping wagons.
It is a twin vertical-screw type, hind. operated, and provided with a ratchetcontrolled winding shaft to prevent back running. At each screvebase is fitted a Hoffmann ball thrust washer which, by reducing friction, reduces the tipping effort to a minimum.
. One of the features of the gear is the stout sub-frame. Most heavy lorry bodies will be badly strained if tipped from one end while holding a load of from four to six tons. This is the reason why a subframe is necessary. In the Shard this frame is --constructed tof channel steel of 6-in. by 2-in. section and pivoted to brackets attached to the chassis side members. The utilization of this subframe also ensures; easy fitting of the tipping gear, the body-being removed and then bolted direct to the sob-frame as if this were the chassis.
The Iprice of the sub-frame is £5 5s., B40 whilst the gear for loads of from three to six tons costs £30 complete with all fittings. A smaller gear to carry 30 cwt. is also marketedThis is priced at L25. S.E.
