Ready-mixed concrete lorry drum - has coaxial internal tube with spiral of opposite pitch to mixing spiral

The drum is for a ready-mixed concrete transporting lorry, having a double-start mixing spiral on the inside. It has a length of tube (3) with a spiral (5) of opposite pitch to that of the drum (1) mounted inside the latter and coaxial to it. The tube can be mounted in the base of the drum outlet, a flap can be provided to shut off the latter when the funnel is in position for filling, mixing or transport.

Salvage device for overturned travelling concrete mixer - is ring attached to end of drum for cable to discharge contents

The concrete mixing and transporting drum mounted on a lorry includes a system of quickly emptying the drum in case of an accident on the road, since the concrete hardens quickly, and if not removed, renders the drum useless. A ring (15) is mounted on the end face (10) of the drum, around the bearing plate (11) so that a cable (14) can be passed around it, to tilt the drum. The ring can be made of steel angle with one face (15) attached to a strengthening plate (13) around the end flange (8) on the drive shaft (7), near the middle of the flange. Alternatively, the strengthening plate rests on the periphery of this flange. In another design, the cable support can be an extension of the flange itself. In a further design, the support can consist of a ring shaped plate bolted onto the flange, projecting from it.

CASTERED LOAD-TRANSFER AXLE STABILIZER

TITLE OF THE INVENTION: Castered Load-Transfer Axle Stabilizer INVENTORS: William J. Mohrbacker \A Earl C. Thayer ASSIGNEE: REXNORD INC., a Wisconsin corporation The load supported and transferred by the rear auxiliary axle of a truck is commonly determined by the fluid pressure supportively disposed between the auxiliary axle and the rear end of the truck frame. Where the auxiliary axle is some distance to the rear of the truck for that purpose, the wheels are castered to avoid scuffing. The castering, however, must generally be damped to avoid fluttering of the wheels and shimmying of the axle. Frictional damping means which is here disclosed is both adjustable and varied automatically with the amount of such pressure and the amount of load transformed. In particular the stability of the vehicle is greatly improved.

The direction switching valve 20 has a function of adjusting the flow cross sectional area of the pressurized hydraulic oil supplied from the variable displacement hydraulic pump 10 to the hydraulic motor 81. The variable displacement hydraulic pump 10 is driven by the internal combustion engine 60 together with the charge pump 11. When the discharge pressure of the charge pump 11 is low, the direction switching valve 20 maintains a small flow cross-sectional area, thereby rotating the mixer drum 1 at low speed to suppress fuel consumption of the internal combustion engine 60. When the discharge pressure of the charge pump 11 increases, the direction switching valve 20 enlarges the cross sectional area, thereby realizing the rated rotation of the mixer drum 1.
