In a lifting drive mechanism, first and second masts extend in the vertical direction. A lift platform is configured to be lifted or lowered along the first and second masts. A hanging belt includes a first end fixed to an upper portion of the lift platform and a second end fixed to the lower portion of the lift platform. An upper pulley supports the hanging belt. A driving pulley moves the hanging belt in a positive direction and a negative direction. An idler pulley is arranged in front of, in back of, or on both side of the drive pulley. A lower pulley is lower than the upper pulley and supports the hanging belt. A supporting member is pivotable around a fulcrum spaced away from a rotation center of the lower pulley in the horizontal direction, and is fixed. The supporting member includes a first end extending from the fulcrum in the horizontal direction and supporting the lower pulley such that the lower pulley is pivotable.

A plurality of control elements extend from the base portion of a control module in a materials handling vehicle. The control elements are located adjacent to one another, wherein at least one of the control elements includes mounting structure that permits the control element to be selectively mounted to the base portion in at least first and second positions. The first position defines a first distance between the control element and an immediately adjacent control element and the second position defines a second distance between the control element and the immediately adjacent control element, the second distance being greater than the first.

A mounting bar assembly mounted to a materials handling vehicle includes a mounting bar extending from a body portion of the materials handling vehicle, a housing mounted to the mounting bar and supporting at least one electronic device, and cabling that extends to the housing through a hollow interior portion defined within the mounting bar. The mounting bar assembly further includes cabling for providing communication between the at least one electronic device and control structure of the vehicle. The housing is mounted to the mounting bar such that the housing can be situated in a plurality of positions along at least a portion of the length of the mounting bar while the cabling is maintained within the hollow interior portion.

A tiller head for a pedestrian and rider forklift includes an upper cover and operating elements, which are connected to a control device to execute a desired operation command execution. The control device is a functionally ready prepared unit for all functions of the respectively desired operation command execution. The control device is arranged at a central point in the tiller head and is constructed such that the operating elements directly engage elements in the control device in a form-fitting manner during installation.

An automatic guided vehicle comprising a fork carriage with a fork, a propulsion drive system, a sensor to acquire position data of objects located in a detection field and a computer. The vehicle comprises a reference member located in the detection field of the sensor rigidly secured to a common rigid frame with the sensor. The sensor periodically acquires control position data indicative of a position of the reference member. The computer periodically compares the control position data with a reference value stored in a memory.

A hose header for a lift truck mast is constructed to inhibit wear of hydraulic hoses.

The invention relates to a machine (1) for handling loads (24), comprising: —a frame (2) equipped with a driving station (15), —a load handling system (4) carried by the frame, a device (6) for controlling the load handling system (4), wherein this control device (6) that can be manually actuated by an operator comprises a manual part (61) configured to be manually grasped, —a control unit (5), the control unit (5) being configured to receive control signals from said control device (6), —a member (7) for activating the manually actuatable control device (6), wherein the control unit (5), in the actuated state of the activating member (7), is configured to authorize the control of the handling system (4) as a function of at least the control signals received from the control device (6), characterized in that the driving station (15) is equipped with a detection system (16) for detecting a presence or absence of the operator at said station (15), this detection system (16) comprising at least one presence sensor (17) distinct from the control device (6), and characterized in that the control unit (5), in the non-actuated state of the activating member (7) and after passing from the actuated state to the non-actuated state of the activating member (7), is configured to prevent or authorize the control at least of the handling system (4) with the control device (6) at least as a function of the absence or presence status of the operator detected by the system (16) for detecting a presence of the operator at said station (15).

A control system includes: a sway detection unit configured to detect a reference swaying amount that is a swaying amount of a mast at a detection height, which is set to be greater than or equal to a height of a lowermost part of a transfer apparatus when a lift is located at an upper limit of a lifting range; a lifting height acquiring unit configured to acquire lifting height information that indicates a lifting height, which is a height of the lift, at a plurality of points in time; and a transfer control unit configured to control the transfer apparatus. The transfer control unit converts the reference swaying amount detected by the sway detection unit into a lifting height swaying amount that is a swaying amount of the mast at the lifting height indicated by the lifting height information.
