Power Pallet Truck (CANBUS Handle)

By using the most modern hall-sensors, common wearing parts such as potentiometers are replaced by contant less control parts. There is further improvement for the hall sensor technology on the PCB of noblelift handle: The normal constructer is touse a microswitch could have mechanical abrasion that leads to the zero point excursion after long period of time All the signals output from the PCB are digital; Compared with the normal analog signal, the digital signal is much more reliable, and with strong anti-disturbance capability of the PCB also in creases much. CAN-Bus interface significantly decreases the number of the wiring, which leads to reduce the fault rate of the truck; Thus the reliability of the truck increases much. With CAN-Bus framework, it is wasy to check and eliminate the fault by connecting an external equipment, for example, a laptop computer. With CAN-Bus framework, it is convenient to integrate different CAN protocol for different speed controllers in the CPU of the PCB; The handle can match with different speed controllers by some simple settings for the handle. Therefore, when the truck changes to another type of the controller, the PCB is the same version and not necessary to change the handle's PCB. By special sealing process aprotection is guaranteed to IP53. Rain doesn't endanger the working realiability. The handle uses rocker switches for the lift/lower function. Compared with the normal switches, the rocker switch has the following advantages: Constructer is much simple. To realiza the lift/lower function, normally it needs two separate standard switches; While the rocker switch integrates the lift/lower function in only one button. The rocker switch is much more stable, and service is simple. The normal switch consists of 6PCS of parts, then one set of switches consist of 12PCS of parts; However a rocker switch for lift/lower only consists of 4PCS of parts. The rocker switch is not only stable, but also is service convenient. The rocker switch takes the modern hall sensor technology for signal creation. Compared with the normal signal creation method with microswitch, this is an innovative technology progress: No mechanical abrasion, much more reliable. The rocker switch realizes that, the customer can select On-off or proportional output for lift/lower function with no change for the switch and PCB itself. It only needs to change the settings of the software of the PCB. That is, for some high requirement for the truck, for example, proportional lift/lower, there is no cost increase on the handle. The traditional way is, different switches have to be used for the On-off or the proportional output; Moreover, the PCB is the different version. Normally, the handle with proportional lift/lower function is much expensive than it with On-off function, the cost is at least15% higher. Therefore, with the rocker condtructer, the different functions are unified by only one switch. The truck design becomes simple, and the cost advantage is obvious. The tiller handle is based modular and compact design; There consists less individual components; The connection between the parts is simple clipon connection. Then the assembly/disassembly and maintenance becomes very convenient. Snailn function takes light-youch switch design, and there is LED to indicate the speed status. That is, touch the switch once, the speed becomes low, and LED changes to green to indicate the low speed mode; Touch the switch once again, the speed recovers to high, and LED changes to red to indicate the high speed mode. Excellent ergonomic design makes the operator easily to use and not to feel fatigue.
