A detached pin pulling accessory for removing pins locking a bogie to a trailer chassis. The puller is intended for use with a trailer having pin pulling equipment which is intended to be pulled by hand. The pin pulling equipment has a handle extending toward the side of the trailer, on which a pulling force is exerted by a first person while a second person rocks the trailer by moving the tractor. The inventive accessory clamps to the trailer and engages the pulling handle of the apparatus, and is self-supporting once these connections are made. An integral crank is wound, which places tension on a spring acting on the pulling handle. The spring maintains tension on the pin pulling equipment without requiring the first person to be present. Thus, releasing pins from a trailer is rendered a one-person task by the novel accessory. The novel accessory requires no external power, such as pneumatic or electrical, and is portable from vehicle to vehicle.
