The articulated mechanical balanced manipulator SHBM-250-M pro is a device designed to mechanize manual lifting and handling of heavy loads. It is equipped with an electromechanical drive and a balanced articulated linkage structure, ensuring precise, smooth, and safe control with minimal physical effort from the operator.
Purpose and Design Features
The SHBM-250-M is designed for safe handling of loads weighing up to 250 kg. Compared with the SHBM-150-M and SHBM-175-M models, this version features a reinforced structure suitable for higher loads. The manipulator consists of a drive head mounted on a rotary support unit with 360° rotation capability. All rotary joints are assembled on rolling bearings, ensuring smooth and stable boom rotation even under load.
The articulated boom, consisting of a main and secondary arm, is balanced by a spring system. This allows the operator to move the load horizontally with virtually no effort — only the inertia of the object needs to be overcome. A gripper head is located at the end of the boom; it rotates around the vertical axis and is equipped with a rigid clamp for interchangeable grippers. The control handle allows precise control of vertical movements.
Standardization and Compatibility with Grippers
The SHBM-250-M can be equipped with any load-handling devices specified in the technical requirements. The standardized design allows the equipment to be easily adapted to various tasks without modifications. The rigid mounting of the load-handling device is especially effective in areas with restricted overhead access, for example when servicing machine tools, furnaces, containers, and other equipment with upper covers or protruding upper elements.
Control System
Vertical load movement is performed manually using a handle that controls the direction and speed of movement. The greater the handle tilt angle, the higher the speed. When released, the handle automatically returns to the neutral position and the load stops. Boom rotation is provided by an electromechanical drive. All control operations can be performed with one hand. Only a few hours are required for the operator to fully master the equipment.
Manipulator Structure
The main structural elements of the SHBM-250-M pro manipulator include:
- Drive head — mounted on the support structure via a rotary support unit, allowing 360° rotation around the vertical axis. The entire rotating part is assembled on rolling bearings, ensuring smooth and stable movement even under full load.
- Articulated boom — consists of a main and secondary arm, is connected to the drive head, and provides radial movement. The boom is balanced by a spring device, enabling almost effortless horizontal movement of the gripper head — the operator only needs to overcome the inertia of the load.
- Gripper head — mounted at the end of the secondary arm and capable of rotating around its vertical axis. It is fitted with a rigid clamp designed for interchangeable load-handling devices. This solution makes it possible to quickly adapt the manipulator to different types of loads without changing the structure.
- Control handle — located on the gripper head and used for manual control of vertical load movement, as well as for force transmission during horizontal movements. When the long end of the handle is tilted upward, the load rises; when it is tilted downward, the load lowers. Movement speed depends on the handle tilt angle. When released, the handle returns to the neutral position, fixing the load at the current height.
- Lifting mechanism — mounted on the drive head and includes a gear motor and rack-and-pinion transmission. This enables precise adjustment of vertical movement and ensures reliable operation.
- Electric drive — built using modern components, including a gear motor with an electromagnetic brake and a frequency converter. This solution provides smooth speed control, increased reliability, and safe operation.
Functional features and additional components:
- Load holding mechanism — allows the load to be stopped and fixed at any height for an unlimited period; when the handle is released, the gripper head is automatically locked.
- No radial or tangential displacement — when at rest, the load remains in position without unintended movement.
- Limit switches — restrict the upper and lower vertical positions, preventing travel beyond the permissible stroke.
- Intuitive control — allows the load to be moved with one hand without requiring special skills.
- Easy operator training — personnel training takes no more than a few hours.
- Synchronized operation — several manipulators can be used together when handling long loads such as pipes, beams, or rails.
- Operation in areas with restricted overhead access — the rigid gripper mounting allows servicing equipment with protruding upper elements where cranes or hoists cannot be used.
- Quick gripper replacement — performed manually, without tools, in just a few minutes.
The safety system includes:
- Emergency stop button — located on the handle and instantly stops lifting when activated;
- Light indication — displays frequency converter modes, overload status, and power connection;
- Protection system — includes overload protection and self-diagnostics of limit switches.
The model is designed for intensive operation and is focused on production tasks that require high precision, convenience, and safety when handling heavy loads.
