To provide a six-wheeled transport carriage having an intermediate wheel in which brake force can be applied to the intermediate wheel irrespective of a direction (turn angle) of the intermediate wheel.SOLUTION: A transport carriage comprising: an intermediate wheel turn control mechanism which has four free wheels 2 provided on each corner part of a deck part 1 and a pair of intermediate wheels 3 provided at a longitudinal intermediate position of the deck part 1, and switches the intermediate wheels 3 between a free wheel state and a stationery wheel state; and an intermediate wheel brake mechanism which brakes the intermediate wheels 3. In the transport carriage, the intermediate wheel brake mechanism has a brake control part 4 which applies a brake force to the intermediate wheels 3. This brake control part 4 is provided on a turn central part of an intermediate wheel fitting part 5 which is so provided on the deck part 1 as to be capable of freely turning and on which the intermediate wheels 3 are provided, and is operated irrespective of a turn angle of the intermediate wheels 3 and can apply brake force to the intermediate wheels 3.SELECTED DRAWING: Figure 1
【課題】中間輪を有する六輪タイプの運搬台車において、中間輪の向き(旋回角度)に関わらず中間輪に制動力を付与することができる運搬台車を提供することを目的とする。【解決手段】荷台部1の各隅部に設けられる四つの自在輪2と、荷台部1の長手方向中間位置に設けられる一対の中間輪3とを有し、中間輪3を自在輪状態と固定輪状態に切り替える中間輪旋回制御機構と、中間輪3を制動する中間輪制動機構を備える運搬台車において、中間輪制動機構は、中間輪3に制動力を付与する制動制御部4を有し、この制動制御部4は、荷台部1に旋回自在に設けられ中間輪3が設けられる中間輪取付部5の旋回中心部に設けられていて、中間輪3の旋回角度に関わらず作動して該中間輪3に制動力を付与することができるように構成されている。【選択図】図1
