Abstract: A mobile lift device having a load moving device capable of engaging a load is provided. The mobile lift device includes one or more systems for stabilizing the mobile lift device during operation of the load moving device. According to one exemplary embodiment, the mobile lift device is a heavy duty wrecker having a rotatable boom assembly. The heavy duty wrecker comprises a monitoring system for stabilizing the wrecker during operation of the boom assembly. The monitoring system comprises a plurality of sensors and a monitoring circuit coupled to the sensors to generate a force signal representative of at least one force being applied to the wrecker based upon the transmitted signals.

Abstract: An improved wheel-lift assembly is provided for towing vehicles on a wrecker. The wheel-lift assembly is adapted to be mounted on the rear deck of the wrecker. The wheel-lift tow assembly includes a relatively thin crossbar assembly, a pair of pivotal lifting arms, and multiple hydraulic cylinders. Two of the hydraulic cylinders are connected to support arms, and thereby control the position of the lifting arms. The hydraulic cylinders are positioned on an outboud portion of the wheel-lift assembly. The wheel-lift assembly includes over-center locking devices for securely locking the lifting arms in place during towing. The wheel-lift assembly may also include reinforcements on the lift arms to create a wear zone for identifying usual wear due to improper usage.

Abstract: A method is described for making concrete mixture by blending new batch cement with recycled concrete material (curb & gutter, sidewalk, brick, block, asphalt & various other concrete items). This new process will enable discarded concrete materials to be reused as a valuable product.

Abstract: A safety chain storage pocket for use with a tow truck comprises a user access surface with a gull wing opening defining a chain access opening providing safety chain exit and storage from and to the pocket. A pair of slotted wings extend from the opening to provide a pair of chain locking positions. The opening has a lower surface providing free movement of the safety chain out of the pocket by allowing the weight of the chain to assist the user to pull the chain out of the pocket, and the chain access opening allows the user vertical access into the pocket to use the weight of the chain to store the chain in the pocket. The slotted wings extend proximate to the chain access opening to provide a locking position for said safety chain.
