Hamersham

Hamersham has significant experience in the Materials Handling sector. Working in the materials handling environment brings on the challenge of making a machine highly productive, efficient, capable, stable, reliable and cost effective to purchase. We have function development experience encompassing:

Diesel Engine Control

Control of larger diesel engines via CAN J1939. Understanding torque curves and implementing stable antistall measures. High and low idle manipulation for transmission integration and static cooling. Pedal response tuning.

Stability/Overturning Moment Control

Implementation of complex weigh and limitation alogorithms to protect both machine stability and mechanical lift capacity. Fast weight calibration routines. Smooth function slow down and limitation that will ensure the machine is easy and reassuring to operate.

Cooling Control

Control of hydraulic proportional fan drive valves. Implementation of the most efficient cooling curves.

Hydrostatic Drive Control

Hamersham has experience in delivering stable hydrostatic control that gives the right "feel" for the driver in terms of braking and acceleration but takes care of power limitation, safety functions, temperature protection, engine overspeed and auxilliary hydraulic load.

Envelope Control

Using sensor feedback and high resolution hydraulic valve control, Hamersham has implemented envelope and position control functions in materials handling applications: Vertical lift, level extend, "go to" positions, height limitation....

Safety Critical Functions

Any function that is considered safety critical can now be implemented, architecture permitting, to EN13489-1 performance level "d" using the new IQAN MC3 controller.
