摘要:
An adjustable backrest assembly for a materials handling vehicle. The backrest assembly includes an adjustable backrest structure and mounting structure for mounting the adjustable backrest structure on the materials handling vehicle so that the adjustable backrest structure extends generally vertically over load handling apparatus of the materials handling vehicle. The mounting structure enables pivoting movement of the adjustable backrest structure from a first position generally adjacent a power unit of the materials handling vehicle wherein pallets of a first size are accommodated to at least a second position spaced along the load handling apparatus from the power unit wherein pallets of a second size are accommodated.

A fork lift truck is provided comprising: a power unit including an operator's compartment and at least one equipment compartment; a pair of forks; a fork carriage assembly coupled to the forks; and a mast assembly. The mast assembly is coupled to the fork carriage assembly and the power unit for vertically moving the fork carriage assembly including the forks relative to the power unit. A hydraulic pump system is also provided. It has at least one hydraulic motor/pump assembly mounted in the at least one equipment compartment and at least one fluid reservoir located laterally of the mast assembly.

A fork lift truck includes a body, a drive mechanism supported on the body for effecting movement of the body, and a fork carrying assembly carrying forks which can be moved in height between a lowered position and desired raised positions. A tilt cylinder is provided for tilting the forks through a fork tilt range. The truck further includes a pressure sensor capable of generating signals indicative of the weight of a load on the forks, a fork tilt position sensor capable of being activated when the forks are tilted to extremes of the fork tilt range, and a controller. The controller is coupled to the drive mechanism, the pressure sensor and the fork tilt position sensor. It causes the drive mechanism to effect movement of the body up to a first maximum speed when at least one of the pressure sensor generates a signal indicative of a load on the forks having a weight above a predetermined value and the tilt position sensor is activated, and causes the drive mechanism to effect movement of the body up to a second maximum speed which is greater than the first maximum speed when the pressure sensor generates a signal indicative of no load or a load on the forks having a weight below the predetermined value and the tilt position sensor is inactivated. The lowering speed of the forks can also or alternatively be increased under the same operating conditions.

A fork lift truck capacity monitor or alerting device informs operators of the weight on the forks and fork height and alerts operators whenever truck speed is above creep with the forks raised above a collapsed height or whenever the forks are raised above a recommended height for a given load. The alerting device includes a control circuit that receives inputs from a speed sensor, a fork height sensor and a weight sensor and reads a memory storing data correlating load weights with maximum recommended fork heights. A truck icon is displayed on a display panel. A plurality of height zone lamps representing the weight of the load on the forks are arranged in a vertical column over the truck icon and selectively illuminated according to the load on the forks. A plurality of lamps represent the height of the forks with the fork height lamps, which include one lamp positioned to represent a lowered position of the forks and a plurality of lamps equal in number to the height zone lamps and placed horizontally opposite therefrom, being selectively illuminated according to the height of the forks. An alarm signal alerts operators whenever the forks are raised above the recommended height for a given load weight, or whenever truck speed exceeds a predetermined maximum speed and the forks are above the collapsed height. The alarm signal may include a combination of an audible signal, a text message, and a flashing lamp.
摘要:
An improved pallet truck, having an extended length pair of forks capable of supporting multiple, side-by-side, pallets which may be raised well above the floor to assist an operator in an order selection operation, includes a first fork lifting mechanism connected to one end of a pair of primary forks. A pair of load wheels are mounted on levers at a other end of the forks and are mechanically connected to the first fork lifting mechanism which causes the other end of the primary forks to be raised from a lower level to an upper level simultaneously with the raising of the first end thereby to maintain the primary forks level while lifting the maximum capacity of the truck. A pair of secondary forks are mounted above the primary forks and are movable from a nested position with respect to the first forks to a raised position by a second fork lifting mechanism carried by the primary forks. The ends of the secondary forks are supported by a pair of hydraulic cylinders attached between the secondary forks and the primary forks, thus providing support and rigidity to the secondary forks while they are in a raised position.
