Patent number: 11473965Abstract: A device for moving a load comprises a mobile, in particular rolling chassis (10) from which a lifting device (20) extends with at least one lifting member (30). The lifting device is intended and configured to receive the load (5) thereon. The lifting member comprises a substantially L-shaped base (31) with a lying leg (311) and an upright leg (312) mutually connected by a bend (313). The lifting member further comprises a shoe (33) which extends over the base (31) with interposing of at least one weight sensor (32) of electronic weighing means. The shoe (33) is likewise substantially L-shaped with a lying leg (331) and an upright leg (332), wherein the upright leg (332) of the shoe (33) maintains an intermediate space in relation to the upright leg (312) of the base (31). A base unit (40) of the weighing means is received at least substantially wholly in the intermediate space between the two legs (31,33).Type: GrantFiled: June 7, 2018Date of Patent: October 18, 2022Assignee: RAVAS EUROPE B.V.Inventor: Niels Van Den Berg

Patent number: 10899375Abstract: A pallet truck comprises a rolling frame (10) and at least one force sensor (51, 52) for registering and generating as electronic output signal a loading of a load platform (20). The force sensor is coupled to electronic processing means for receiving and processing the output signal, and display means (65) are provided for generating a visual weight indication. At least a part of the processing means is accommodated together with a first electronic power supply in a first housing (50) forming part of the frame (10). The display means (65) are arranged together with a second electronic power supply in a second housing (60) on or close to a handle (45) of an operating arm. A wired first connection (56) is provided between the force sensor (51, 52) and the processing means. Telecommunication means are provided for establishing and maintaining a wireless second connection (57) between the first housing (50) and the second housing (60).Type: GrantFiled: November 7, 2017Date of Patent: January 26, 2021Assignee: RAVAS EUROPE B.

Patent number: 10745261Abstract: A lifting vehicle comprises a mobile chassis with a tiltable mast (3) and a lifting device (4,5). Alerting means (15,16) are provided for the purpose of monitoring a load on the lifting device as a result of a cargo being carried thereby. The alerting means comprise a first electronic sensor 11), which records a cargo weight, and a second electronic sensor (12) which records a cargo moment. The alerting means (15,16) are provided with automatic calibration means which, when an output signal below a predetermined threshold value is generated by the one sensor (11), sets to zero an output signal differing therefrom from the other sensor (12).Type: GrantFiled: October 31, 2016Date of Patent: August 18, 2020Assignee: RAVAS EUROPE B.V.Inventor: Niels Van Den Berg

Patent number: 9902602Abstract: A device 1 includes a carrying body for carrying a load. The carrying body includes a first wall 3 which receives the load and an opposite second wall 2. Between the first wall and the second wall is a space in which a force sensor is provided. A part of the force sensor 4 is coupled to the second wall 2 and the other part of the force sensor extends beyond an edge of the second wall 2 so that the force sensor has some freedom to bend. An at least partially bendable force transmission body 5 is fixed to the first wall 3 and extends in a cavity 6 in the other part of the force sensor. Owing to the force transmission body 5 the force sensor is loaded only in a direction to which the force sensor is tuned.Type: GrantFiled: July 6, 2012Date of Patent: February 27, 2018Assignee: RAVAS EUROPE B.V.Inventor: Henri Peter Maria Van Seumeren

Patent number: 9845228Abstract: A Lift truck with a lifting device comprises at least one lifting member (1) provided with lifting means for adjusting the lifting member in height direction. The lifting member (1) comprises a shell part (50) lying over a base part (2) and having a surface on which cargo can be received. The shell part supports from a pressure point on the base part (2) via an electronic force sensor (10). The force sensor (10) is able and configured to determine vertical load on the shell part (50) and to generate an electronic signal as measure thereof, and comprises for this purpose pressure and/or strain-sensitive sensor means.Type: GrantFiled: February 6, 2014Date of Patent: December 19, 2017Assignee: RAVAS EUROPE B.V.Inventor: Henri Peter Maria Van Seumeren

Publication number: 20130126806Abstract: A hand lift truck comprises a rolling frame (10 . . . 13) with at least one height-adjustable load platform (11,12) for receiving a cargo thereon. Electronic weighing means (70) are herein provided to determine a mechanical deformation of a part (13) of the frame resulting from a loading of the load platform and to determine therefrom a weight indication of an actual loading of the load platform and to display this to a user on a display panel (85). According to the invention height-indicating means which indicate the reference height are provided in the form of an electronic sensor (88) which determines a height adjustment of the load platform by electronic means and generates an electronic height signal thereof to electronic processing means. The processing means determine therefrom an actual height of the load platform and are coupled to signalling means for the purpose, at least when the reference height is reached, of generating an indication thereof the user.Type: ApplicationFiled: April 13, 2011Publication date: May 23, 2013Applicant: RAVAS EUROPE B.V.Inventor: Henri Peter Maria Van Seumeren

Patent number: 6855894Abstract: A mobile lifting device comprises a mobile frame (1, 12, 13) with a set of lift forks (3) for receiving a pallet thereon. The pallet truck is provided with a weighing device which comprises at least one pressure or strain-sensitive sensor (20) in addition to a display panel (21) for indicating thereon a value measured by the sensor. The sensor is connected firmly to a pan (12) of the frame and able to determine a mechanical deformation in that part of the frame. The weighing device comprises this sensor.Type: GrantFiled: July 12, 2000Date of Patent: February 15, 2005Assignee: Ravas Europe B.V.Inventor: Henri Peter Maria Van Seumeren
