  • Patent number: 4093091
    Abstract: An improved load moment sensing system for a lift truck having tilt and lift cylinders for tilting a mast and lifting a carriage on the mast, respectively. A sensor is provided for sensing the load moment placed on the frame and a sensor is provided for determining when the carriage is elevated on the mast. A logic system is responsive to the sensors for preventing actuation of the tilt and lift cylinders simultaneously when an overload is sensed while allowing rearward tilting only when an overload has been sensed and when the carriage is elevated. The system also prevents tilting forwardly when an overload has been sensed and when the carriage is elevated. The system also allows tilting forwardly when an overload has been sensed and the carriage is not elevated.

  • Patent number: 4091741
    Abstract: A security device adapted to be applied to retain in closed relation container doors for lading against access into the container. The security device has a shelf portion with an upright arm secured thereto and adapted to be disposed in the path of opening movement of one or both of the container doors to prevent opening movement of the doors sufficiently to gain access to the lading in the container. The arm may be a part of an upright angle bar which forms a support for one end portion of the shelf portion while the opposite end of the shelf portion is supported by a rear upright member. The shelf portion is preferably yieldable to accommodate containers supported in different positions with respect to the surface of the transport vehicle. The upright arm may have a laterally extending arm connected therewith whereby the security device will have a retaining device in the path of both doors. Provision is made for discouraging cutting of the upright arm so as to remove it from the path of the door.

  • Patent number: 4090616
    Abstract: A hay handling device is mounted in a vehicle bed to load, carry, and unload large hay bales. A rugged frame of the device is securely held in the vehicle bed by brackets which release the frame in selective fashion to permit its removal. A horizontal support member which is pivoted to the frame carries a central spear which is adapted to penetrate a bale resting on the ground. The spear is secured to a small sleeve which is slidably mounted on an upright post so that the elevation of the spear can be adjusted in order to accommodate bales of various sizes and vehicle beds of different heights. Shorter spears are located on opposite sides of the central spear to cooperate in handling the hay bale. A power winch operates on the upright post to pivot the support member in a manner to raise a bale which the spears have penetrated.

  • Patent number: 4090628
    Abstract: A forklift clamp having first and second arms extending horizontally outwardly and having generally flat outsides and insides and a thin cross section whereby the arms may readily move into and out of small spaces. At least one of the arms is movable toward the other arm for supporting a load therebetween. At least one of the arms is pivotally connected at its inner end to a vertical frame and hydraulic power means rotates the pivoting arm about the pivot inwardly for moving the outer ends of the arms toward each other for uniformly distributing the gripping pressure of the flat insides of the arm on a load, and rotate the arm outwardly for providing an operating clearance between the outer ends of the arms and the load. Preferably, the arms are decreasingly tapering in thickness from the inner ends towards the outer ends for decreasing the operating clearance required. Preferably, the arms are supported in horizontal tracks which are rotated for rotating the arms.

  • Patent number: 4090453
    Abstract: Apparatus for rerailing derailed wheels of a railway vehicle includes a bridge which is positioned beneath a derailed vehicle end. After the vehicle is leveled, a lifting jack disposed on a carriage mounted on the bridge supportingly elevates the derailed vehicle end and moves the supported derailed end over the rails, the bridge being positioned to return the derailed vehicles to a position over the rails. Since the wheels of the opposed vehicle end are stationary, the derailed vehicle end is moved along an arcuate path. A motive means such as a jack moves the carriage along the bridge axis, and supporting roller means on the carriage enable the lifting jack engaging the vehicle to move transversely to the bridge axis thereby allowing the jack and supported vehicle end to traverse an arcuate path while fully supported.
