A wheel chock has a body with a shell and filled core construction capable of supporting high chocking loads while being relatively lightweight and portable. The chock includes walls sized and shaped to support large-diameter wheels such as wheels of large haul vehicles and mining trucks. The chock can be sized proportional to the radius of the wheel to be retained or based on the radius of curvature of a wall configured to primarily support the outer surface of the wheel. The chock can have a cut off or flattened toe or front surface that reduces weight and helps to ensure that the entire chock is load-bearing when in a chocking position. The chock can also have a flattened top surface to support the outer surface of a tire that deforms around the chock while it is being retained by the chock.

A wheel chock system comprising at least one wheel chock for supporting a vehicle, detecting a load imparted by the vehicle, and displaying information indicative of the load imparted by the vehicle is described herein. In some embodiments, the wheel chock detects a load imparted by a vehicle with a load sensor and displays the load. The wheel chock may be in communication with other wheel chocks supporting the vehicle. The wheel chocks may display the loads detected by all wheel chocks and may determine and display a load distribution across all wheel chocks.

A tie-down for attachment to an aft tail section of an aircraft for inhibiting damage to the aircraft when the aircraft is on the ground is disclosed. The tie-down has a mount member configured to attach to the aft tail section and a projection member supported by the mount member. The projection member extends in a generally downward direction from the mount member so as to provide a contact surface with the ground that is lower than the aft tail section.

A flying machine storage container is provided that comprises multiple charging stations and a clamping mechanism. The clamping mechanism is configured to secure flying machines in the charging stations and securely close charging circuits between the storage container and the flying machines. A system for launching flying machines is also provided. The system comprises two regions and a transition region between the two regions. The two regions each constrain the positioning of a flying machine and the transition region enables a flying machine to move from the first region to the second region to reach an exit. A flying machine having sufficient performance capabilities will be able to successfully launch. Centralized and decentralized communication architectures are also provided for communicating data between a central control system, multiple storage containers, and multiple stored flying machines stored at each of the storage containers.

The wheel chock is part of a wheel chock restraint system that also includes a base plate to prevent a parked vehicle from moving away in an unauthorized or accidental manner in a departure direction. The wheel chock includes a main body having a bottom base portion and a tire-engaging bulge. It also includes a tire deformation cavity, made within the main body on the tire-facing side. Teeth are provided underneath the bottom base portion of the wheel chock to engage at least one among corresponding teeth provided on the base plate in a latched engagement. The wheel chock has an improved resistance to rollover and tipping when the wheel is pressed forcefully against the wheel chock.

An improved wheel chock for use with wheeled vehicles, such as aircraft, that is both adjustable in size and that is configured for relatively easy transport, deployment and maneuverability by a single user is disclosed. The wheel chock preferably comprises a lifting end, a rolling end, at least one segment positioned between the lifting end and the rolling end, and a unique and adjustable wheel assembly. The adjustable wheel assembly may be at least partially housed in a pocket formed in the rolling end of the improved wheel chock. The wheel chock may further comprise a tether and an opening for removably attaching said wheel chock to a second wheel chock to prevent unwanted movement of a vehicle wheel in both forward and reverse directions.

A deployable chock for a trailer includes a chock hingedly secured to an underside portion of a trailer. The chock is capable of deployment to abut a front or a rear of a wheel of the trailer to prevent a tractor trailer from moving and capable of stowing out of the way when not in use.

Wheel chock apparatus including a plurality of wedge members configured to be positioned adjacent to a wheel. Each wedge member comprises a first end and a second opposite end, where a first flexible member is configured to attach to the first ends of each of the plurality of wedge members and a second flexible member is configured to attached to the second opposite ends of each of the plurality of wedge members. The first and second flexible members are configured to adjust a relative distance between the plurality of wedge members. In some examples, the wheel chock apparatus includes a chain and a tightening strap for adjusting the relative distance. In some further examples, the wheel chock apparatus includes locking mechanisms to prevent theft of the machine attached to the wheel and the wheel chock apparatus itself.
