The portable hoist is divided into five categories: indoor jib, outdoor jib, full-angle, mobile, and straight forward. The overall structure is divided into two parts: the main machine and the bracket.
1. The main engine is composed of a motor, a reducer, a clutch, a brake, a rope drum and a steel wire rope. The motor is a magneto-magnetic single-phase capacitor motor, designed with a mechanism that brakes when the power is turned off; the motor is also equipped with a thermal switch to prevent the motor from overheating and burning; the reducer is a two-stage gear reduction, which is fixed to the motor; clutch, The brake is integrated with the rope drum. When the clutch is in the disengaged state, it can achieve rapid descent, and the brake can be operated to control the descent speed to avoid impact. The round hole on the front of the mainframe can be used to install a blower, and the user can equip it with a blower for forced cooling as needed. Equipped with a strong cooling fan model, the user can start the strong cooling fan at any time as needed.
2.1 The rotating arm indoor bracket is composed of screw, jack nut, pole, post, rod top cap and rotating arm, etc., using the principle of screw and jack nut, the host and bracket can be stably installed in the space with the support top surface , Realize the lifting operation up and down. When the cargo is hoisted to the target height, the rotating arm can move the cargo horizontally.
2.2 The outdoor bracket of the rotating arm is composed of a vertical rod, a rotating arm, a flat rod, a diagonal rod, an upper joint, a lower joint, and a tail joint. The mainframe and the bracket are connected by the joint, and the tail joint can be moved up and down by pressing an appropriate weight at the tail joint. Lifting operations. When the cargo is hoisted to the target height, the rotating arm can move the cargo horizontally.
2.3 The mobile bracket is composed of a base with four wheels (the two wheels are designed to be steerable when the direction is moving), a vertical pole, a telescopic vertical pole, an auxiliary vertical pole, a diagonal pole and an arm. The host is installed at the front of the base, and an appropriate counterweight is pressed on the rear of the base to carry out lifting operations. When the cargo is hoisted to the target height, move the machine and the cargo horizontally back and forth. The user can equip two 40 ×40 or 50×50 angle steels to install under the four wheels of the base according to the specific conditions of the ground to make the horizontal movement more flexible.
2.4 The straight-moving bracket is divided into two parts: a fixed frame and a sliding frame. The fixed frame is composed of three uprights and a beam. The main frame is installed on the movable frame, and it is installed on the beam through four walking wheels. The upright column is composed of a screw rod and an upright rod, and the upright rod and the screw rod are fixed between the ground and the ceiling through a nut. The beam is fixed in the middle of the three columns through beam joints and cross arms. Move the movable rack to an appropriate position during operation. After the goods are hoisted to the target height, push and pull the sliding rack to make the goods move horizontally along the beam.
This product adopts 220V single-phase power supply, and realizes the forward and reverse rotation of the motor by operating the button switch, thereby winding and releasing the steel wire rope. The wire rope is hoisted and lowered by the pulleys of the bracket part to complete the lifting operation.
