The present invention relates to an industrial hydraulic actuator safety device for maintenance of an industrial hydraulic actuator. The device includes one or more supports including composite material, and retainers for retaining the supports at either end. Advantageously, the supports may be lightweight enabling the safety device to be conveniently moved and installed by a single person without exposing the person to significant risk of injury. The supports may be durable, resisting any actuator forces, and the safety device may be installed more safely and/or quicker than alternative steel safety devices.
B23P 19/04 - Machines for simply fitting together or separating metal parts or objects, or metal and non-metal parts, whether or not involving some deformationTools or devices therefor so far as not provided for in other classes for assembling or disassembling parts
B25B 27/00 - Hand tools or bench devices, specially adapted for fitting together or separating parts or objects whether or not involving some deformation, not otherwise provided for
B29C 70/52 - Pultrusion, i.e. forming and compressing by continuously pulling through a die
B29K 83/00 - Use of polymers having silicon, with or without sulfur, nitrogen, oxygen or carbon only, in the main chain, as moulding material
B29K 103/00 - Use of resin-bonded materials as moulding material
B29K 277/00 - Use of polyamides, e.g. polyesteramides, as reinforcement
F15B 15/16 - Fluid-actuated devices for displacing a member from one position to anotherGearing associated therewith characterised by the construction of the motor unit of the straight-cylinder type of the telescopic type
Provided is a jack stand that includes a base and a post for extending from the base. A top is provided for topping the post and engaging with a load. The top includes a load spreader for spreading the weight of the load to the post. Advantageously, the spreader spreads the weight of the load to the post thereby resulting in a more heavy duty jack-stand, rated for significantly higher loads, than prior jack stands which instead can fracture under heavy unbalanced loads locally travelling along one side when the loading is not evenly spread.
B25H 1/00 - Work benchesPortable stands or supports for positioning portable tools or work to be operated on thereby
F16M 11/22 - Undercarriages with or without wheels with approximately constant height, e.g. with constant length of column or of legs
G01G 19/02 - Weighing apparatus or methods adapted for special purposes not provided for in groups for weighing wheeled or rolling bodies, e.g. vehicles

The present invention relates to a jack stand. The jack stand includes a base. A post, including composite material, extends from the base. The jack stand also includes a top for topping the post and for engaging with a load. Advantageously, the post may be lightweight (typically less than 12kg) enabling the jack stand to be conveniently moved by a single person without exposing the person to significant risk of injury. The jack stand may be moved as a whole, or in parts.
