Materials handling vehicle and goods storage and retrieval system comprising mobile storage carts, transporters, and materials handling vehicles
Goods storage and retrieval systems and materials handling vehicles are provided. The goods storage and retrieval system includes a multilevel warehouse racking system; a materials handling vehicle comprising a mast assembly, a picking attachment, and vehicle-based cart engagement hardware; a mobile storage cart; and a transporter comprising transporter-based engagement hardware. The transporter-based engagement hardware enables the transporter to engage, transport, and disengage the mobile storage cart. The vehicle-based cart engagement hardware is coupled to the mast assembly to (i) engage and disengage the mobile storage cart and (ii) transport the mobile storage cart to multiple levels of the multilevel warehouse racking system. The mast assembly and the picking attachment are configured to access multiple levels of the multilevel warehouse racking system. The picking attachment is configured to transfer totes between the multilevel warehouse racking system and the mobile storage cart.
1. A materials handling vehicle comprising:
a vehicle body;
a plurality of wheels supporting the vehicle body and defining a direction of travel for the vehicle body;
a braking system, a traction control unit, and a steering assembly, each operatively coupled to one or more of the plurality of wheels;
a mast assembly;
a monofork carriage assembly coupled to the mast assembly for movement along a lifting dimension of the mast assembly, the monofork carriage assembly defining an operator compartment width oriented across the direction of travel of the vehicle body, the operator compartment width being between about 100 cm and about 125 cm, the monofork carriage assembly comprising a unitary materials handling platform oriented across the direction of travel of the vehicle body and defining a platform width parallel to the operator compartment width, the platform width being at least about 75 cm and being less than the operator compartment width; and
a transport, engagement, or disengagement accessory configured to facilitate transport, engagement, or disengagement of materials by the materials handling vehicle, wherein the monofork carriage assembly comprises a hollow body portion accommodating at least a portion of the transport, engagement, or disengagement accessory therein.
2. The materials handling vehicle of claim 1 , wherein:
the unitary materials handling platform comprises a leading face that is oriented across the direction of travel of the vehicle body; and
the leading face of the platform forms a protruding arc that extends across the platform width and protrudes along the direction of travel of the vehicle body.
3. The materials handling vehicle of claim 1 , wherein:
the unitary materials handling platform comprises at least two opposing pairs of vertically oriented cart stabilizers;
the two opposing pairs of cart stabilizers are located on opposite sides of the unitary materials handling platform along the direction of travel of the vehicle body; and
each cart stabilizer comprises an inclined contact edge facing an opposing inclined contact edge of a cart stabilizer on an opposite side of the unitary materials handling platform.
