of Undue Lifting Stresses triE accompanying illustration shows 1 a new model of the Milshaw tipping gear, produced by the Milshsw Tipping Gear Co., Ltd., Birch Lane
Works, Rooley Lane, Bradford. It possesses several outstanding features, amongst whic'h are the unit construction of the ran] body and static oil tank, the vertical disposition of the gear behind the cab, and the fact that the load is slung from the end of the 'third-stage ramrod The assembly consists ot triple telescopic rams giving a three-stage lift, with the cylinder of the master ram built integral with the static oil tank. The latter is trunnion-mounted across the chassis just behind the cab, the process of installing being thus reduced to the simplest possible form.
It will be appreciated that the lift comes at the most advantageous point —where the maximum leverage over the body and its load is obtained. This, of course, applies to all types of tipping gear arranged at the forward end, as in this case. There is much less stress on the gear, body and chassis.
A point of some interest is that the lift is taken directly on the body bearers via two pivoted arms which are taken up to a fixed head on the small ramrod. Such a form of construction should relieve the body of much stress, whilst, at the same time, the lifting gear is in the most advantageous position to exert the maximum lift with a minimum of effort, In all cases, irrespective of the type of gear fitted, the rams, when at rest, come well below the height of the cab, and when in action do not come above the front boards of the body. This latter feature is of some importance, because there can be no possibility of the ram gear being caught up in overhead obstruction, should it be necessary, as it often is, to move the vehicle when in the tipped position. The special form of construction adopted in the case of the oil tank and ram body, whereby the latter is taken through the tank, imparts stability to the rams. Incidentally, the tank body is made of material of stout section, as through it is taken the full thrust of the load.
Very little space is required for installation, as may be gathered from the example illustrated, in which the distance between the back of the cab and front board of the body is only 54 ins.
