The invention discloses a good-stability electric hoist portal crane which comprises a base, a fixed block is fixedly connected to the top of the base, a through hole is formed in the fixed block, a sliding beam is movably connected to the interior of the through hole, a large pulley is slidably connected to the inner wall of the sliding beam, and a sliding arm is hinged to the middle of the large pulley. The bottom of the sliding arm is fixedly connected with a lifting arm, and the end, away from the sliding arm, of the lifting arm is fixedly connected with a lifting hook. The cargo boom is started, the cargo boom drives the lifting hook to move, the lifting hook drives an object needing to be lifted to conduct lifting movement, when the object runs on the lifting hook, the lifting object continuously swings left and right, a certain influence can be generated on the cargo boom, and damage to the cargo boom can be accelerated due to long-time swinging; and a series of springs are used for damping, so that the lifting object and the crane body can be protected and stabilized.

    本发明公开了一种稳定性好的电动葫芦门式起重机,包括基座,所述基座的顶部固定连接有固定块,所述固定块的内部设有通孔,所述通孔的内部活动连接有滑动梁,所述滑动梁的内壁滑动连接有大滑轮,所述大滑轮的中间铰接有滑动臂,所述滑动臂的底部固定连接有起重臂,所述起重臂远离滑动臂的一端固定连接有起重钩。本发明通过启动起重臂,起重臂带动起重钩运动,起重钩带动所需要起重的物品进行起重移动,当物品在起重钩上进行运转时,起重物不断的左右摇摆会对起重臂产生一定的影响,长时间的摇摆会加速起重臂的损坏,通过一系列的弹簧进行减震对起重物与起重机本体都能达到保护稳定的作用。
