CDm and MDm electric hoists are used in CD₁、 MD₁The steel wire rope electric hoist, based on the modified design of the type electric hoist, has two lifting capacities of 5t and 10t, which are modified from CD, MD 3t, and 5t hoists respectively. The lifting height is available in four specifications: 6m, 9m, 12m, and 15m.
With CD₁、 MD₁Compared to traditional electric hoists, CDm and MDm electric hoists have the following characteristics:
1. The lifting speeds are 4m/min (single speed) and 4/0.4m/min (dual speed), suitable for use in situations where slower lifting speeds are required;
2. The power of the lifting motor is higher than that of a CD with the same lifting capacity₁、 MD₁Gourds should be much smaller to save energy;
3. The gourd has a small clearance height, making it suitable for use in low clearance situations;
4. Adopting a new octagonal double pulley system hook design to shorten the length and size of the hoist;
5. Improved the winding method of the steel wire rope, avoiding the cross phenomenon of the steel wire rope during the lifting process of the hoist.
