Low-chassis electric trolley

Abstract

A low-chassis electric trolley includes a platform with a ramp pivotally mounted on its rear, right, or left side. A stop is provided on the side of the platform without the ramp. The platform height is lower than the highest point of the steerable motor drive wheel. An electrical control box is located on the front side of the platform, with a footboard in front of the control box. An operating handle is located above the control box, and a speed control device on the handle electrically connects to the electrical control system and motor within the control box. The operating handle drives the steerable motor drive wheel. The control box is positioned at the front end of the operator's standing side, allowing the weight of the operator and the control box to press against the steerable motor drive wheel, increasing friction and effectively preventing slippage. This allows the trolley to be pushed in from three sides. The operator can stand or sit on the footboard or seat in front of the control box. Guardrails are provided around the platform to prevent falls and ensure operational safety.

Claims

1. A low-chassis electric trolley, comprising: A platform, with a ramp pivotally mounted on its rear, right, or left side, and a stop on the side of the platform not equipped with the ramp; the ramp is lowered to allow a cargo trolley to be selectively pushed onto the platform from the rear, right, or left side, and then the ramp is closed; several wheels are mounted on the rear bottom surface of the platform; an electrical control box, fixed to a front side of the platform, with an electrical control system and several batteries assembled inside or outside the control box; a steerable motor drive wheel at the bottom of the control box; the electrical control system electrically connecting the batteries to the steerable motor drive wheel; and an operating handle, located above the control box, which drives the steerable motor drive wheel to perform straight-line or steer movements; a speed control device on the operating handle electrically connected to the electrical control system.

2. The low-chassis electric trolley as described in claim 1 further includes a footboard, which is fixed to the side of the control box for the operator to stand on.

3. The low-chassis electric trolley as described in claim 2, wherein the pedal may be a fixed pedal, a telescopic pedal, or a folding pedal.

4. The low-chassis electric trolley as described in claim 2, wherein a guardrail is provided around the footboard to prevent accidents to personnel during transport.

5. The low-chassis electric trolley as described in claim 2, wherein a folding seat is provided above the footboard, the folding seat being fixed to one side of the control box by welding, screwing or riveting, for the operator to sit and rest during operation, and folded up when not in use.

6. The low-chassis electric trolley as described in claim 2, wherein a fixed seat is provided above the footboard for the operator to sit and rest during operation and to be folded up when not in use.

7. The low-chassis electric trolley as claimed in claim 1, wherein the ramp is retracted upwards against one side of the stop and is secured by at least one set of fasteners, fasteners or a bolt.

8. The low-chassis electric trolley as described in claim 1, wherein the steerable motor drive wheel on the bottom surface of the control box may be a single wheel or a double wheel, and an auxiliary wheel may be provided on each side of the steerable motor drive wheel.

9. The low-chassis electric trolley as described in claim 1, wherein a number of batteries are assembled inside or outside the control box, the batteries being fastened in a quick-change or fixed manner, and the batteries being either lithium batteries or lead-acid batteries.
