Problems solved by technology

But what stands in the way of electric carts are their two inherent disadvantages
The first downside is the price, as even the smallest electric carts are a lot more expensive than those that are fully manually propelled
The second disadvantage is that the electric cart is relatively large, so it cannot be flexibly maneuvered in a limited space like a manually propelled cart

Embodiment Construction

[0011] The cart shown in the accompanying drawings comprises two fork frames 1 identical to common manual carts, wherein the rear ends of the fork frames are connected to the beams, and the upper ends of the two beams 2 extending obliquely upwards, backwards and inwards pass through A bell 3 is connected to accommodate the piston rod of a lifting cylinder 4 , while the lower end of the lifting cylinder is fixed to a pressure plate 5 connected to a guide wheel 6 . On this pressure plate is fixed the pump cylinder of the hydraulic system which can be pivoted up and down by the rudder stock which is pivotally connected to the lift cylinder by the cart.

[0012] At the front end of the lifting fork, support rollers 7 are arranged on arms 8 which are movable between a lowered load lifting position and a raised load free position. Said movement is achieved by means of rods 20 connected in turn to arms 9 connected to two axes 19 of said frame at the rear end of the cart, one on each ...

Abstract

Tiller truck with manually driven lifting and electric transport driving where two short batteries (11) are placed on each other between the inward inclined side frame beams (2) of the truck and with parts of the transfer mechanic for the lifting movement to the front support wheels (7) arranged between the side frame parts (2) and the batteries (11).

Description

[0001] This divisional application is based on the divisional application of the Chinese patent application with the application number 2003801090611, the application date is December 17, 2003, and the invention name is "electric cart". Background technique [0002] In order to enable the goods on the loading chassis to be moved, it is known to use electric carts instead of manually steered ones. But what hinders electric carts are two inherent disadvantages. The first downside is price, as even the smallest electric strollers are a lot more expensive than those that are fully manually propelled. The second disadvantage is that electric carts are relatively large, so they cannot be maneuvered flexibly in a limited space like manually propelled carts. The gap between manual and electric carts is so great and due to the sometimes enormous need to reorganize or rebuild space, a change to the use of electric carts is required. [0003] From the above it is evident that there is ...
