Material Handling Solutions

Product catalog summary

Introduction
HydraForce is a leading manufacturer of hydraulic cartridge valves, manifold systems, and electronic controls. The document provides technical information on their products and solutions, particularly focusing on material handling solutions.

Early Applications and Challenges
Initial applications of AC pump motors with proportional valves aimed to synchronize pump speed with valve opening. This required significant development time and was inefficient due to valve irregularities, pump efficiencies, and system wear.

Benefits of HydraForce Solutions

Lower system pressure drop and improved load/no-load speeds with software-optimized pressure compensation.
Cost savings by reducing mechanical components and battery power consumption.
Increased mounting flexibility with smaller manifold blocks.
Control algorithms monitor pressure transducer inputs to calculate exact flow supply.
Additional algorithms for pump wear, volumetric efficiency, and viscosity changes.
Options programmable at the dealer or in the field.
High load stability at lowering-start due to removal of spring-loaded mechanical compensators.
Very low leakage due to poppet-style seating in lowering control valves.

Material Handling Solutions
HydraForce's solution involves using a CAN networked ECU to enhance performance and efficiency in material handling machines. This includes electro-proportional valves with sensors and electronics to improve machine performance and safety while reducing system components.

System Concept and Products

Accessory Valve Controller for multi-function vehicles due to limited I/O in AC traction control units.
5-way proportional valves available for various flow capacities.
SP08-58C and SP08-58D valves reduce sensor requirements and eliminate load shuttles.
RVD50-20 valve provides effective pressure limiting with low hysteresis and leakage.
Proportional directional control valves offer excellent linearity and repeatability.
High accuracy pressure sensors replace mechanical compensators.

Global Presence and Compliance
HydraForce has facilities in the USA, UK, China, India, and Korea. Their products meet RoHS environmental requirements and OSHA standards, ensuring limited use of hazardous materials.

Material Handling Solutions Early applications of AC pump motors combined with proportional valves attempted to match the speed of the pump to the opening of the valve. This was done by either creating a lookup table in the memory of the controller or by calibrating the valve i-min and i-max points and generating a linear relationship between valve opening and pump speed. Either option required signicant development time and is still inefcient due to irregularities of valves, pump efciencies, and system wear. By communicating with engines and pumps using a CAN networked ECU it is possible to...

Material Handling Solutions SYSTEM CONCEPT Since most AC traction control units lack sufcient I/O to do all the sensing and drive more than a few valves, an Accessory Valve Controller is used for multi-function vehicles. In order to eliminate the number of wires running through the mast sheaves, a CAN node has been employed to operate the carriage manifold and any sensors, limit switches or position transducers that are mounted on the mast. Operator Inputs Because everything is electronic, limits can be established to provide overrunning load control for both directions of the reach function....
