Manual handling of loads (MHL) or manual material handling (MMH) involves the use of the human body to lift, lower, carry or transfer loads. The average person is exposed to manual lifting of loads in the work place, in recreational atmospheres, and even in the home.
Manual material handling tasks may expose workers to physical risk factors. If these tasks are performed repeatedly or over long periods of time, they can lead to fatigue and injury. The main risk factors, or conditions, associated with the development of injuries in manual material handling tasks include: Awkward postures (e.g., bending, twisting)
Better efficiency: Material handling equipment helps streamline the movement of products. Compared to manual handling, materials handling equipment greatly saves time and effort. [21] Improved safety: When manually handling goods, there are a lot of risks of injuries experienced e.g fall from heights. When unit load formation equipment is ...

When the mast is rotated, the connected boom is swung from to the side. The control of the lifting location is done by the manipulation of the top pulley system and the rotation of the mast at the base. The load is lifted by another pulley system connected to the top of the boom. [2] In a medium load lifting, another construction method can be ...
