MHT2 Series Toggle Joint Heavy-Duty Self-Locking Pneumatic Gripper

Brand: SOLH by Richge Technology

Product Overview

     SOLH MHT2 series is toggle-joint driven 2-jaw pivot angular gripper. Outstanding features include toggle self-locking mechanism, power-off holding capability, ultra-high clamping torque and four-sided sensor installation slots with high structural rigidity.

     Optimized for heavy workpiece clamping, transportation and positioning with strict anti-drop safety requirements; the preferred heavy-load gripper for high-risk automated stations.

Core Structure & Design Features

     -- Working Principle: Cylinder push-pull combined with toggle link force-amplifying mechanism. When jaws close, the toggle reaches dead-point locking position. Clamping force is amplified 3~5 times, and ≥80% clamping force can be maintained continuously upon air pressure loss / air cut-off for reliable safety self-locking.

     -- Body Construction: Square hard anodized aluminum housing with built-in magnetic ring. Four mounting grooves (top/bottom/left/right) allow direct assembly of M9B / A93 series magnetic switches without dead angles for sensor layout.

     -- Operation Type: Double acting (D standard version / DZ updated lightweight version). Jaws lock at closed position; cylinder thrust resets jaws for opening action.

     -- Material Specification: Hard oxidation aluminum cylinder, high-strength alloy steel jaws, wear-resistant linkage assembly. High rigidity, long service life and maintenance-free oil-free operation.

     -- Flexible Mounting: Multiple tapped mounting holes support axial, longitudinal and horizontal installation, suitable for compact confined equipment layout.

Universal Core Technical Specifications (0.5MPa Supply Pressure)

Core Competitive Advantages

  1. Powerful self-locking anti-drop performance

     -- Toggle dead-point locking design retains ≥80% clamping force after air supply cut-off or pressure loss. Effectively eliminate workpiece falling risk for high-safety automated production lines.

  2. Ultra-high clamping torque for heavy-duty tasks

     -- Max torque reaches 106N·m for φ63 model, capable of gripping 5~50kg heavy workpieces, far exceeding parallel grippers with equivalent bore size.

  3. 360° flexible sensor layout

     -- No integrated guide rail on main body; magnetic switches can be mounted on four surfaces to realize all-direction position detection, perfect for narrow installation cavities.

  4. High rigidity & extended service life

     -- Alloy steel jaws and wear-resistant linkages support over 5 million stable cycles, adapted to high-frequency heavy-load continuous operation.

Mounting Options & Typical Application Scenarios

  1. Mounting Forms

     -- Axial mounting: Horizontal push & pull for assembly line material transfer

     -- Longitudinal vertical mounting: Up & down loading/unloading stations

     -- Lateral side mounting: Side clamping for limited-space stations

  2. Typical Industrial Applications

     -- Automotive components: Gripping engine housings, gearbox covers, wheel hubs

     -- Machine tool automation: Heavy casting, forged parts and mold handling

     -- Logistics conveying: Metal pallets, boxes and barrel material transportation

     -- Safety positioning stations: Overhead anti-drop stations, safety clamping fixtures for pressing equipment

Selection Comparison: MHT2 Toggle Gripper VS MHZL2 VS MHL2

3-Step Fast Selection Guide

  1. Bore selection based on workpiece mass

     -- 32 ≤ 5kg；40 = 5~15kg；50 = 15~30kg；63 = 30~50kg. Reserve minimum 30% load safety margin.

  2. Swing angle verification

     -- Max opening angle: MHT2-32 up to 28°, MHT2-63 limited to 23°. Confirm sufficient clearance for target workpiece dimension.

  3. Configuration matching

     -- Position feedback requirement: Choose DZ lightweight version + M9B magnetic switch for four-side sensor mounting

     -- High safety overhead handling: Prioritize MHT2 for its unique power-off self-locking feature

One Sentence Summary

     SOLH MHT2 toggle joint self-locking pneumatic gripper adopts dead-point linkage force amplification structure with power-off anti-drop clamping capability, four-side magnetic switch mounting and high alloy rigidity, available in D / DZ variants, ideal heavy-duty safety gripper for automotive parts, casting and overhead heavy workpiece machine tool loading/unloading automation.
